Hi Everyone,
      Our seminar speaker on Wednesday is Dr. Amy Bonsor from IOA, Cambridge.  She'll be arriving on campus around 12:00.  We'll plan to go to lunch at Lakeside Arts around 1pm.  If anyone would like to join for lunch, please let me know by tomorrow evening (as usual, we can subsidize a few post-graduate students).

Amy's talk is titled: Rocky planets and the potential for life beyond the Solar System

The abstract is provided below.

On Wednesday, the timings of the events are:

Arrival ~ 12:00pm
Lunch ~ 1:00pm
meet the speaker for postgrads at 15:00, finishing at 15:30
seminar at 15:45 in C5 (new room)
post-seminar WINE AND CHEESE

Amy will have a bit of free time during the day, so if anyone would like to meet with her, please let me know.  As of now, the plan is for her to sit in my office A108.


Cheers,
Jesse and Luke

Abstract:
We live in an epoch of exoplanet discovery. Within the next decade the discovery of rocky planets orbiting other stars will be commonplace. However, in order to fully understand these exoplanetary systems and their potential to host life, we have to consider the planetary system as a whole. Information from host-star compositions, system architectures and white dwarfs that have accreted planetary material add to our intuition. I will discuss how we can start to think about whether exoplanetary systems have the right material available and the right physical conditions for the origin of life. Our exploration of planetary systems beyond the Solar System goes hand in hand with the journey of discovery of how life on Earth came to be.

The Formation and Evolution Massive Galaxies in the Cosmos and their Circumgalactic Environment

Contrary to many stereotypes about massive galaxies, the observed systems are  diverse in their star formation rates, kinematic properties, and morphologies.  Studying how they evolve into and express such diverse characteristics is an important piece of the galaxy formation puzzle.     Here, we focus on a subset of massive galaxies, the brightest group galaxies (BGGs).  We use a high-resolution cosmological suite of simulations based on the Romulus galaxy formation model, and compare simulated central galaxies in group-scale halos at ? = 0 to their observed counterparts.  Since most galaxy formation models are calibrated using measures that are strongly influenced by the properties and evolution of ?normal?  Milky-Way like galaxies, this exercise is also an opportunity to test the limits of these models. The comparison encompasses the stellar mass-halo mass relation, various kinematic properties and scaling relations, morphologies, and the star formation rates. We find Romulus BGGs that are early-type S0 and elliptical galaxies as well as late-type disk galaxies; we find BGGs that are fast-rotators as well as slow-rotators; and we observe BGGs transforming from late-type to early-type following strong dynamical interactions with satellites.  In short, we find that Romulus reproduces the full spectrum of diversity in the properties of the BGGs very well.  Additionally, due to its superb  mass and spatial resolution, Romulus also offers a unique window onto the joint evolution of the BGGs and the surrounding intragroup medium. With respect to the latter, we are able to observe the emergence of multiphase structure - in the form of cold clouds - in the intragroup medium.  Groups also experience  repeated AGN feedback episodes that drive  large-scale collimated outflows into the IGrM.  While the present resolution does not allow direct exploration of the coupling between the clouds and the AGN jets, we argue that the clouds will cause the SMBHs (and hence, the jets) to change direction every so often.  Returning back to the BGGs, we find that early type galaxies can rejuvenate by growing disks, in agreement with recent observations.  However, we also note a tendency towards lower than the observed fraction of quenched BGGs, with increasing halo mass.  The problem appears to be due to decreasing effectiveness of AGN feedback with increasing halo mass.  Examining some of the other galaxy formation models, we find that they too run into trouble on the same scale ? but in an opposite sense. I will conclude by discussing what we are to make of this and what the path forward looks like.

            Seminar date: 1st  October, Tuesday 1 pm

           Venue: Seminar Room A 113

            Title: Inflationary Models in String Theory

Abstract: In this talk, I will discuss a phenomenon called cosmic inflation in which the Universe went through accelerated expansion to solve the horizon problem of Cosmological Microwave Background within a billionth of a trillionth of a trillionth of a second, in the very early Universe. This accelerated expansion, in its minimal form, is driven by a scalar field (inflaton) and it takes place when this scalar field slowly rolls down a potential well. However, the origin of this scalar field and the correct form of the scalar potential remains an open question in cosmology. I will present a string theory motivated model where the inflaton is connected to the geometry of the internal space -- the overall volume of it drives the inflation. In particular, I will present a construction where the overall volume modulus (scalar field) is dynamically stabilized to an exponentially large value only via perturbative corrections, also known as perturbative large volume scenario (LVS). In this framework, the robustness of the single-field inflationary model is checked against possible sub-leading corrections. In the later part of my talk, I will focus on the global embedding of the fibre inflation in perturbative LVS and show how our constructions pose less challenge in realizing a successful period of inflation.

Dear all.

As I'm sure you have all noticed, the heating was turned on in CAPT today. That is good news and it means the boiler works and the heating system is operational.

Unfortunately, that is where the good news ends. A leak has been identified which means the system has had to be shut down. They are working on fixing the leak as soon as possible.

At least the building is now nice and warm...

I will keep you posted.

Best wishes,

Dear all (students, postdocs, and staff).

Please read and keep this message for info.

Most you know that the University is moving to a new finance and admin system called UniCore. During the changeover period from the current one to the new one there will be unavoidable disruption. In particular there will be cutover period when a number of things will not be available.

The attached file details some of the key deadlines and how they will impact us over cutover. We have pulled out the main areas, but please also refer to the Unicore cutover page<https://uniofnottm.sharepoint.com/sites/DigitalCoreProject/SitePages/Preparing-for-the-rollout-of-UniCore.aspx> for additional information if required. I would like to highlight two areas that have been of the most concern. Information is in the pack, but can I draw your attention to the following:

Purchasing:

Orders on Agresso must be placed by the end of Sunday 20th October. We will not be able to order from that point so please consider and plan for anything you might need in that period.
There will be an emergency purchase process by exception only. This will be authorised by the faculty, and must be for emergencies (eg, essential research equipment that has broken), and not an item we have failed to order in time.

Travel:

Personal expenses while travelling can continue to be accrued, then claimed on the new system when live. Air plus cards will still work for payments of expenses while travelling, but you will not be able to use them to book any travel.

Expenses to visitors will not be processed until the system is up and running. Please let any visitors (e.g., speakers) know and apologies.

Please refer to the web page linked above for further information. Any further concerns / queries can be raised with @Rebecca Craig (staff)<mailto:brzrlw1 at exmail.nottingham.ac.uk> (our school Unicore lead) or Martyn Fisher.

Best wishes,

Alfonso

Dear All,
                    We have two seminars this week, as given below.

  1.
Speaker: Theo Anton  (QMUL)

            Seminar date: 8 October, Tuesday 1 pm

           Venue: Seminar Room A 113

            Title: Generalised tests of gravity in cosmology

Abstract: A plethora of modified theories of gravity have been proposed over the last several decades. Testing them all observationally is a considerable challenge, so it is advantageous to develop theory-independent approaches that constrain deviations from General Relativity in a systematic way. Many of the most precise such constraints to date are obtained from astrophysical measurements, for which deviations from GR are described by the parameterised post-Newtonian (PPN) parameters. Some attempts have been made to perform similarly general tests on cosmological scales, but it is not clear that they refer to the same couplings as the PPN formalism does, and so interpreting results from these disparate regimes physically is difficult and potentially misleading. With that problem in mind, I will introduce a framework, called parameterised post-Newtonian cosmology, that allows information from cosmological and astrophysical regimes to be combined consistently. I will present novel constraints on the evolution of the PPN parameters over cosmic history, using data from CMB anisotropies and Solar System experiments concurrently, and I will explain how these ideas can be further applied to test cosmological gravity to high precision.

            Seminar date: 10 October, Thursday 3 pm (Journal Club time)

           Venue: Seminar Room A 113

            Title: Multi-metric black holes and the Gregory-Laflamme instability

Abstract: Multi-metric gravity is the umbrella term for a class of modified gravitational theories, motivated by a number of problems at the interface between gravity and particle physics, that extend general relativity (GR) via the inclusion of additional interacting massive spin-2 fields beyond the single massless graviton of GR. Nonlinearly, the extra interactions manifest as a framework where multiple metric tensors interact with one another on the same spacetime manifold (hence the name). To date, black hole solutions of these multi-metric theories are only understood for the simplest case of bigravity (N=2 metrics) in 4 dimensions. It is, for example, known that one class of bigravity black holes is unstable for certain values of the graviton mass, with the instability taking the same form as the notorious Gregory-Laflamme (GL) instability plaguing higher dimensional black strings, although this feature has previously been viewed as little more than a peculiarity. In this talk, I will show how to generalise the 4d bigravity results to the full multi-metric theory in arbitrary dimension, constructing a wide class of black hole solutions of the general theory, and determine their linear stability. I will also elucidate the link between the instabilities of these multi-metric black holes and those of higher dimensional black strings. The result seems to suggest that the GL instability may be more fundamentally linked to the nature of massive spin-2 interactions.

Investigating AGN activity in recently quenched galaxies at cosmic noon


We still do not understand the processes responsible for quenching star formation in massive galaxies, particularly in the distant Universe. AGN feedback is favoured by theoretical models, but so far direct observational evidence is limited. To tackle this problem, I will present a new Chandra X-ray analysis of AGN activity in a large sample of over 500 recently quenched galaxies at cosmic noon (1<z<3). Preliminary results reveal strong links between black hole activity and star formation, but the role of AGN in directly quenching star formation appears to be more subtle than current models predict.

Message-ID: <3D231E7D-C190-4BBA-932D-CBD5456E90E6@nottingham.ac.uk>

Hi all,

this week's astronomy seminar will be given by Elke Roediger, talking about interpreting cluster merger observations. Elke will be here all day on Wed.

Post-seminar refreshments will be wine and cheese.

Timings are as usual:

- lunch at Lakeside, leaving CAPT ~13:00 (subsidised for a limited number of students - let me know before the end of the day tomorrow)
- meet the speaker for postgrads at 15:00, finishing at 15:30
- seminar at 15:45 in C5
- post-seminar wine and cheese at 16:45

This seminar will be conducted in person only.

Best,
Jesse and Luke

Interpreting cluster merger observations: catching some devils in the details

In minor galaxy cluster mergers, several interesting gas dynamics phenomena take place. These include the formation of a bow shock by the supersonically infalling smaller merger partner, an enhanced stagnation point pressure just upstream of the infalling subcluster, gas stripping of the smaller partner, and gas sloshing of the larger host cluster. Theoretical and numerical work has advanced our understanding of these processes and their associated observable signatures. These effects, or similar ones, are also known in Earth-bound gas flows, and simple analytical estimates have been used to derive properties such as merger ages and infall speeds from observations. However, the applied methods often rely on at least quasi-steady gas flow conditions, which can?t be assumed in cluster mergers due to density gradients in the ICM and non-constant merger velocities. 
I report on two lines of our research: We investigate to what extent the non-steady state nature of gas flows in mergers biases measurements of merger velocities, and we present an analytical toy model for cluster sloshing.

Hi all,

Tomorrow (08/10) will be the announcement of the Nobel Prize in Physics 2024. It starts at 10:45 am, and we booked Physics B17 to watch the announcement together.

Last year we watched it in A113, but this year A113 has been booked by the astro people for their journal club, so we have to move over to the main building.

See you tomorrow!

Trevor

Hello all,
You are warmly invited to the first session of the CAPT Coding Club (CCC), this Friday at 2 PM in A113.
The aim of these sessions is to create an informal, open-forum environment where we can bring coding problems we're stuck on, share useful tips and tricks, and ultimately work toward becoming more efficient programmers.
For the first meeting, we?ll have an introduction session to discuss the topics and directions we want to explore between now and the new year. Each meeting will also function as an open problem-solving session, so feel free to bring along any coding issues or bugs you're currently facing.
I already have some suggestions for future sessions that I?d be happy to lead, such as general coding practices, using GitHub, setting up VSCode, optimising NumPy performance, and making Matplotlib plots more visually appealing.
We have some extremely talented programmers with diverse skill sets in the department, so I encourage everyone to attend and help fill in any gaps in our collective knowledge. I'm happy to handle the organisation and lead discussions, but it would be great to have others lead sessions on topics such as using Linux, setting up captain/HPC, using AstroPy, working with languages beyond Python, and much more!
I hope to see you all there on Friday!
Happy coding,
Bradley

With that problem in mind, I will introduce a framework, called parameterised post-Newtonian cosmology, that allows information from cosmological and astrophysical regimes to be combined consistently. I will present novel constraints on the evolution of the PPN parameters over cosmic history, using data from CMB anisotropies and Solar System experiments concurrently, and I will explain how these ideas can be further applied to test cosmological gravity to high precision.

            Title: Multi-metric black holes and the Gregory-Laflamme instability

Abstract: Multi-metric gravity is the umbrella term for a class of modified gravitational theories, motivated by a number of problems at the interface between gravity and particle physics, that extend general relativity (GR) via the inclusion of additional interacting massive spin-2 fields beyond the single massless graviton of GR. Nonlinearly, the extra interactions manifest as a framework where multiple metric tensors interact with one another on the same spacetime manifold (hence the name). To date, black hole solutions of these multi-metric theories are only understood for the simplest case of bigravity (N=2 metrics) in 4 dimensions. It is, for example, known that one class of bigravity black holes is unstable for certain values of the graviton mass, with the instability taking the same form as the notorious Gregory-Laflamme (GL) instability plaguing higher dimensional black strings, although this feature has previously been viewed as little more than a peculiarity. In this talk, I will show how to generalise the 4d bigravity results to the full multi-metric theory in arbitrary dimension, constructing a wide class of black hole solutions of the general theory, and determine their linear stability. I will also elucidate the link between the instabilities of these multi-metric black holes and those of higher dimensional black strings. The result seems to suggest that the GL instability may be more fundamentally linked to the nature of massive spin-2 interactions.

Hi Everyone,
       Our Annual Astronomy Jamboree is next Wednesday at 15:45 (the usual seminar slot). As we've again added a number of new faces, this is a great way to get to know more about everyone and do to the current size of the Astronomy group will only be fore members of the Astronomy group.

In keeping with tradition, the idea is to let people know a bit about you and your research, so please send me two slides (in one single file, saved as <firstname>_ <lastname>.pdf) with:

 - slide 1: pictures that tell us something about you, not your work (don?t put your name on it) ? Also don't include photos of yourself ? but do make it fun!
 - slide 2: a brief research summary (put your name on it)

Please send me the photos by Tuesday morning.  Everyone will have ~1 minute to present.  Looking forward to having all of you participate (also if you are unable to attend, please still send slides, just let me know that you can't attend in the e-mail).

In peace,
Jesse

Dear all,

Apologies once again for the lack of updates on the CAPT roof situation - as many may be aware, there has been a complete information drought from Estates on this for the vast proportion of the year.

The roof has now been re-covered with a 20 year warranty system and scaffolding is being altered today to allow re-sealing works to the pyramid skylight roof tomorrow (weather dependent); once this has been completed, the scaffolding will be removed.

Fingers crossed this final work package goes smoothly, and we can look forward to CAPT looking a bit more "normal" in the very near future.

Kind regards,

Nick

Hi Everyone,

This week's lunch talk will be given by Omar on Thursday at 1pm in A113. Title and abstract are below.

Investigating AGN activity in recently quenched galaxies at cosmic noon

We still do not understand the processes responsible for quenching star formation in massive galaxies, particularly in the distant Universe. AGN feedback is favoured by theoretical models, but so far direct observational evidence is limited. To tackle this problem, I will present a new Chandra X-ray analysis of AGN activity in a large sample of over 500 recently quenched galaxies at cosmic noon (1<z<3). Preliminary results reveal strong links between black hole activity and star formation, but the role of AGN in directly quenching star formation appears to be more subtle than current models predict.

Dear all,
As there are a few new faces in the building, I?d like to remind people about fire safety and what to do when the fire alarm sounds continuously.

The recent fire drill went well, with the fire officer happy at how well the building was evacuated. I have been asked to remind people not to wedge fire doors open ? which includes the kitchen door.

In this building we operate a fire-tag system, and the attached document says a few words about this. Basically, if the tag is there when the fire alarm is sounding, please pick it up and clear the floor that it corresponds to. Then leave. That way, when both tags are collected, we know that the building is empty. If you have any questions, please come and have a chat with me.

Best wishes,
Paul.

Subject: [Maths-quantum-gravity-group] Particle Cosmology and Gravity Seminars this week

Dear All,
                    We have two seminars this week, as given below.

  1.
Speaker: Theo Anton  (QMUL)

            Seminar date: 8 October, Tuesday 1 pm

           Venue: Seminar Room A 113

            Title: Generalised tests of gravity in cosmology

Abstract: A plethora of modified theories of gravity have been proposed over the last several decades. Testing them all observationally is a considerable challenge, so it is advantageous to develop theory-independent approaches that constrain deviations from General Relativity in a systematic way. Many of the most precise such constraints to date are obtained from astrophysical measurements, for which deviations from GR are described by the parameterised post-Newtonian (PPN) parameters. Some attempts have been made to perform similarly general tests on cosmological scales, but it is not clear that they refer to the same couplings as the PPN formalism does, and so interpreting results from these disparate regimes physically is difficult and potentially misleading. With that problem in mind, I will introduce a framework, called parameterised post-Newtonian cosmology, that allows information from cosmological and astrophysical regimes to be combined consistently. I will present novel constraints on the evolution of the PPN parameters over cosmic history, using data from CMB anisotropies and Solar System experiments concurrently, and I will explain how these ideas can be further applied to test cosmological gravity to high precision.

           Venue: Seminar Room A 113

            Title: Multi-metric black holes and the Gregory-Laflamme instability

Abstract: Multi-metric gravity is the umbrella term for a class of modified gravitational theories, motivated by a number of problems at the interface between gravity and particle physics, that extend general relativity (GR) via the inclusion of additional interacting massive spin-2 fields beyond the single massless graviton of GR. Nonlinearly, the extra interactions manifest as a framework where multiple metric tensors interact with one another on the same spacetime manifold (hence the name). To date, black hole solutions of these multi-metric theories are only understood for the simplest case of bigravity (N=2 metrics) in 4 dimensions. It is, for example, known that one class of bigravity black holes is unstable for certain values of the graviton mass, with the instability taking the same form as the notorious Gregory-Laflamme (GL) instability plaguing higher dimensional black strings, although this feature has previously been viewed as little more than a peculiarity. In this talk, I will show how to generalise the 4d bigravity results to the full multi-metric theory in arbitrary dimension, constructing a wide class of black hole solutions of the general theory, and determine their linear stability. I will also elucidate the link between the instabilities of these multi-metric black holes and those of higher dimensional black strings. The result seems to suggest that the GL instability may be more fundamentally linked to the nature of massive spin-2 interactions.

Subject: Inaugural CAPT Coding Club - Friday 2pm A113

Hello all,
You are warmly invited to the first session of the CAPT Coding Club (CCC), this Friday at 2 PM in A113.
The aim of these sessions is to create an informal, open-forum environment where we can bring coding problems we're stuck on, share useful tips and tricks, and ultimately work toward becoming more efficient programmers.
For the first meeting, we?ll have an introduction session to discuss the topics and directions we want to explore between now and the new year. Each meeting will also function as an open problem-solving session, so feel free to bring along any coding issues or bugs you're currently facing.
I already have some suggestions for future sessions that I?d be happy to lead, such as general coding practices, using GitHub, setting up VSCode, optimising NumPy performance, and making Matplotlib plots more visually appealing.
We have some extremely talented programmers with diverse skill sets in the department, so I encourage everyone to attend and help fill in any gaps in our collective knowledge. I'm happy to handle the organisation and lead discussions, but it would be great to have others lead sessions on topics such as using Linux, setting up captain/HPC, using AstroPy, working with languages beyond Python, and much more!
I hope to see you all there on Friday!
Happy coding,
Bradley

Dear All,
             We have Eemeli Tomberg visiting from Lancaster this week (on Tuesday and Wednesday) to deliver the Particle Cosmology and Gravity seminar. He will be based in office B112. The details are as follows -

  1.
Speaker: Eemeli Tomberg (Lancaster University)

            Seminar date: 15 October, Tuesday 1 pm

           Venue: Seminar Room A 113  (Cripps North Building)

            Title: Primordial black holes and stochastic inflation

Abstract:  Quantum fluctuations from cosmic inflation give rise to the macroscopic
structures of the universe. The strongest fluctuations collapse into
primordial black holes, a dark matter candidate and a possible source of
gravitational waves. Stochastic inflation is a tool to compute the
fluctuation statistics non-perturbatively, needed for accurate black
hole predictions. I discuss recent progress in these computations, their
numerical implementation and analytical approximations, and the
implications for black hole abundance in inflationary models.

Hi Everyone,

This week's lunch talk will be given by Helen on Thursday at 1pm in A113. Title and abstract are below.

Quasars cooling cluster atmospheres

The impact of quasar feedback on galaxy and cluster hot atmospheres is still largely unknown.  This is principally due to a lack of low-redshift analogues for which we can spatially resolve the quasar's immediate environment.  I will present results from a new large Chandra program on H1821+643, which is the nearest quasar hosted by a galaxy cluster.  Using detailed simulations to subtract the quasar light, I will show that, at the cluster centre, the gas temperature drops precipitously to <0.4keV and the density increases by over an order of magnitude.  Looking to the future, I will also discuss the future of high spatial resolution X-ray observations with AXIS.

Hi Everyone,
      I hope that all of you are doing well.  I wanted to remind you that our annual Astronomy Jamboree is Wednesday at 15:45 in A113!  For those unfamiliar, this is a fun way to introduce yourself (your Astronomy and non-Astronomy interests) to the department!  So far, I've only received a few slides, so do so please send me two slides (in one single file, saved as <firstname>_ <lastname>.pdf) with:


- slide 1: pictures that tell us something about you, not your work (don?t put your name on it) ? Also don't include photos of yourself ? but do make it fun!
 - slide 2: a brief research summary (put your name on it)

Send me your slides by Tuesday morning.

Looking forward to receiving your slides!

In peace,
Jesse

Hi Everyone,
       Our Annual Astronomy Jamboree is next Wednesday at 15:45 (the usual seminar slot). As we've again added a number of new faces, this is a great way to get to know more about everyone and do to the current size of the Astronomy group will only be fore members of the Astronomy group.

In keeping with tradition, the idea is to let people know a bit about you and your research, so please send me two slides (in one single file, saved as <firstname>_ <lastname>.pdf) with:

 - slide 1: pictures that tell us something about you, not your work (don?t put your name on it) ? Also don't include photos of yourself ? but do make it fun!
 - slide 2: a brief research summary (put your name on it)

Please send me the photos by Tuesday morning.  Everyone will have ~1 minute to present.  Looking forward to having all of you participate (also if you are unable to attend, please still send slides, just let me know that you can't attend in the e-mail).

In peace,

Dear all - please could you kindly circulate this announcement for NAM at Durham around your institutes? This first call is for session proposals to be held at NAM. Thank you in advance! Kind regards, Dave


The Royal Astronomical Society is pleased to announce that the 2025 National Astronomy Meeting (NAM2025) will be held at Durham University from Monday 7th July to Friday 11th July. In addition to the UK's broad astronomy community, including the astro-particle and instrumentation communities, the meeting is also focused on the UK Solar Physics (UKSP) community with participation from both the Magnetosphere Ionosphere and Solar-Terrestrial (MIST) and planetary geophysics communities.

NAM2025 is organised in conjunction with Durham University's Centre for Extragalactic Astronomy<https://astro.dur.ac.uk/CEA/>, the Centre for Advanced Instrumentation<https://www.dur.ac.uk/research/institutes-and-centres/advanced-instrumentation/>, the Institute for Computational Cosmology<https://icc.dur.ac.uk/>, the Institute for Particle Physics Phenomenology<https://www.ippp.dur.ac.uk/>, and the Department of Mathematical Sciences<https://www.durham.ac.uk/departments/academic/mathematical-sciences/>.

The call for session-proposal submissions is now open. We encourage members of all communities across all levels of seniority to apply for specialist and cross-disciplinary scientific presentation and discussion sessions. As well as hosting parallel sessions of varying duration, the conference may host collaborative meetings, workshops and lunch sessions. The applicants of any successful proposals will be expected to take on the role of scientific organisers of the session. We also encourage proposals for dedicated sessions on topics relevant to the UK astronomical community, such as professional practice, sustainability, engagement, diversity and inclusion. We note that abstracts will be assessed anonymously and request that applicants take this into account when writing their session-proposal plans.

We are planning a hybrid meeting, in which the majority of participants attend in person, but with the opportunity for remote participation for additional delegates. Session proposers should consider any implications for their proposals. Participant accessibility is a key consideration for NAM2025.

Proposals should be submitted on-line at https://nam2025.astro.durham.ac.uk/abstracts/. Note we are using Indico for NAM2025 and so you will need an account to submit a proposal but, don't worry, an Indico account is quick and easy to create. The deadline for submitting session proposals is Friday 6th Dec 2024 at 17:00 UTC.

For other information about NAM2025, including key deadlines, please see our web page: https://nam2025.astro.durham.ac.uk. For information or queries about NAM2025 please contact the organisers on nam2025 at durham.ac.uk.

Hello Coders,
Thank you to everyone who attended the first CAPT Coding Club (CCC) session!
For those who couldn?t make it, we discussed how we?d like future sessions to run and compiled a list of topics to cover. I?ve also set up a GitHub repository to store resources as we go: github.com/Bradley-March/capt-coding-club<https://github.com/Bradley-March/capt-coding-club>. The list of suggested topics is already available there.
It was agreed that future sessions should be split into two halves:

  *   The first half will focus on a specific topic
  *   The second half will serve as an open forum for anyone to bring in coding issues, bugs, or problems they?re stuck on

For our next session, we?ll spend the full hour on an introduction to CAPT. This will cover the basics of Linux, GitHub, VSCode, SSH, and using captain, giving everyone the tools to build upon in future sessions. Think of it as a setup session to ensure we all have the necessary framework in place.
We also discussed whether Friday is the best day for everyone. After checking room availability, the other possible times for A113 are 11 AM or 1:30 PM on Wednesday. To find the most convenient time for everyone, please take a moment to fill out this form<https://docs.google.com/forms/d/e/1FAIpQLSckl6u6A-izT6x9pdXTWHRXNli8nOuyo8pNDAl-5mkDDb6wlg/viewform?usp=sf_link> to help us decide.

Hi all,

Matt's viva is on Thursday the 7th of November!

The meal will be at Slice 'n' Brew at 6:30 pm. Since it is quite a small venue, we need to book in advance!

TLDR: If you are coming please send me ?10 (?20 if you have a +1 before Thursday October 31st).

If you would like to come, please fill in this Google form by Thursday October 31st with any dietary requirements and confirm if you require a +1:
https://forms.gle/DJBF67v3mjByjzrCA

If you are coming to Matt's viva meal, the restaurant has asked for a deposit of ?10 per person, which will be taken off the group booking of ?22.50 per person that night.

Please could you send me the ?10 deposit to the following details by Thursday October 31st, at which point I will pay the restaurant. If you have requested a +1, please send me ?20.

Please send the deposit with your full name as a reference:

LAUREN CAITLIN HOWE GAUGHAN (If this is too many characters please enter: MISS L C H GAUGHAN)
40-04-00
11787403

Please be aware that after Thursday October 31st, if you can no longer come to the meal, I will not be able to give your deposit back.

We will be given a party sharing menu where we will be given a selection of pizzas, sides, snacks and dips designed to be shared. This menu is here<https://drive.google.com/file/d/1B1GqXEwXI_rjJs-c8wSTI6T-U4pu2smS/view?usp=drive_link>.

Dear all,

Since we have many new arrivals (welcome!), it is probably useful to remind all of you that the School of Physics and Astronomy normal working hours are Monday to Friday between 8:00 and 19:00.  If you need to work outside these hours  you need to:


1)     Discuss it with your supervisor (students) / line manager (postdocs) and get permission from them.

2)     Get an alarm code (your supervisor/line manager should know it; if not please ask me) and make sure you know how to set/unset the alarm.

3)     Make sure you sign in and out in the book at the entrance.

Moreover, if you need to work in the building


a)      Earlier than 6:00 or later than 19:00 Monday to Friday

or

b)     Weekends at any time

you need to contact  Nick Botterill and Peter Milligan and ask for advice/permission.

Please note that these rules are for your own safety.

If in doubt, please come and talk to me.

Best wishes,

Alfonso

Hi Everyone,

This week's lunch talk will be given by Helen on Thursday at 1pm in A113. Title and abstract are below.

Quasars cooling cluster atmospheres

The impact of quasar feedback on galaxy and cluster hot atmospheres is still largely unknown.  This is principally due to a lack of low-redshift analogues for which we can spatially resolve the quasar's immediate environment.  I will present results from a new large Chandra program on H1821+643, which is the nearest quasar hosted by a galaxy cluster.  Using detailed simulations to subtract the quasar light, I will show that, at the cluster centre, the gas temperature drops precipitously to <0.4keV and the density increases by over an order of magnitude.  Looking to the future, I will also discuss the future of high spatial resolution X-ray observations with AXIS.

Dear All,
             We have Ayngaran Thavanesan visiting from Cambridge University this week (from Monday to Thursday) to deliver the seminar and to interact with David Stefanyszyn. He will be based in office B112. The details are as follows (Note that it is an extended seminar 1+1 hour long) -

  1.
Speaker: Ayngaran Thavanesan (DAMTP, Cambridge University)

            Seminar date: 22 October, Tuesday 1 pm

        Regular seminar talk: 1pm - 2pm,
      Extended talk: 2pm - 3 pm (For people who are free, and are interested in hearing the extended part)

           Venue: Seminar Room A 113  (Cripps North Building)

            Title: To dS/CFT and Back Through Cauchy Slice Holography

Abstract:  In this talk, I will first introduce Cauchy Slice Holography (CSH), which uses the TTbar deformation to connect CFT states in a holographic theory to bulk Wheeler-DeWitt states, providing us with a bulk holographic dictionary. Unlike AdS/CFT, de Sitter (dS) space lacks a fully established holographic dictionary, but boundary observables remain constrained by conformal invariance. Using the CSH dictionary, I will show how to flow 2-point correlators from the boundary to a finite-time Poincar? slice of dS, enabling the computation of finite-time cosmological correlators. I?ll highlight key differences from the AdS case.

In the second part, I will explore the TTbar+?d deformation to obtain a CFT dual of global dS by continuing this deformation of a Euclidean CFT with a sparse spectrum to Cauchy slices. Extending the flow past the static patch horizon leads to an imaginary spectrum, allowing an interpretation of the Gibbons-Hawking entropy microstates as living on Euclidean Cauchy slices. The CFT limit is restored as the deformation parameter approaches zero.

Time permitting I will discuss recent explorations for UV-completions of CSH which will thus define non-perturbative bulk quantum gravity.

Ayngaran Thavanesan (DAMTP, Cambridge University)
To dS/CFT and Back Through Cauchy Slice Holography

In this talk, I will first introduce Cauchy Slice Holography (CSH), which uses the TTbar deformation to connect CFT states in a holographic theory to bulk Wheeler-DeWitt states, providing us with a bulk holographic dictionary. Unlike AdS/CFT, de Sitter (dS) space lacks a fully established holographic dictionary, but boundary observables remain constrained by conformal invariance. Using the CSH dictionary, I will show how to flow 2-point correlators from the boundary to a finite-time Poincar? slice of dS, enabling the computation of finite-time cosmological correlators. I?ll highlight key differences from the AdS case.

In the second part, I will explore the TTbar+?d deformation to obtain a CFT dual of global dS by continuing this deformation of a Euclidean CFT with a sparse spectrum to Cauchy slices. Extending the flow past the static patch horizon leads to an imaginary spectrum, allowing an interpretation of the Gibbons-Hawking entropy microstates as living on Euclidean Cauchy slices. The CFT limit is restored as the deformation parameter approaches zero.

Time permitting I will discuss recent explorations for UV-completions of CSH which will thus define non-perturbative bulk quantum gravity.

Wednesday 23rd October, C5 Physics at 3.45pm ? Astronomy Seminar
Haida Lang (NTU)

From Astronomy to Archaeology: multimodal imaging and remote sensing for the study of the history of the Silk Road and much more?



Astronomy studies the history of the universe while archaeology studies the history of the human past. The talk will explore the benefits of interdisciplinary research from fundamental science (e.g. Astrophysics) to applied science and Engineering and how applications to cultural heritage materials can inspire the development of instruments that are useful for industrial monitoring. Inspired by ideas from Astronomy, various remote sensing and interferometric imaging techniques have been developed for cultural heritage material analysis to study history and help art conservation. As the volume of data collected is becoming too large to manage using traditional image analysis methods, machine learning methods are developed to analyse data from automated high resolution large scale surveys of wall paintings such as those in cave temples along the Silk Road. This talk will discuss some of the unexpected contribution of astronomy to the field of heritage science including conservation science and archaeological science.

Hi everyone,

This week?s lunch talk will be given by Jesse Golden-Marx on Thursday at 1pm in A113. Here is the title and abstract:

The Hierarchical Growth of Bright Central Galaxies and Intracluster Light as Traced by the Magnitude Gap

Intracluster light (ICL) is known to surround bright central galaxies (BCGs). However, it remains unclear if the hierarchical growth processes that build the BCG are simultaneously building the ICL. We address this question using 2800 galaxy clusters identified in the Dark Energy Survey across the redshift range 0.20<z<0.60. To quantify hierarchical formation we use the stellar mass - halo mass (SMHM) relation for the BCG+ICL system and incorporate the magnitude gap (M14), the difference in brightness between the BCG (measured within 30kpc) and 4th brightest cluster member galaxy within 0.5 R200c, a parameter which traces BCG hierarchical growth.  We find that the correlation with M14 decreases at large radii from the BCG's centre. However, the stellar light within the BCG+ICL transition region (30kpc - 80kpc) most strongly correlates with the dark matter halo mass and has a statistically significant correlation with M14. As the light in this region and M14 are independent measurements, the transition region may grow as a result of the BCG's hierarchical two-phase formation. Additionally, we use a stacked sample and find that clusters with large M14 values are characterized by larger ICL and BCG+ICL fractions, which illustrates that the merger processes that build the BCG stellar mass also grow the ICL and may suggest that M14 combined with the ICL fraction can be used as a method to identify dynamically relaxed clusters.

See you all there!

Joe

Hello Coders,
Thank you to everyone who attended last Friday?s session, where we covered Linux and GitHub, with a brief introduction to VS Code.
Before this Friday?s session, I recommend following Jimi's instructions in the GitHub repo<https://github.com/Bradley-March/capt-coding-club> to try remotely SSHing into Captain/ODHAR using VS Code. If you haven?t used these machines before, please contact Phil to get your account set up. Also, note that the guide mentions Remote X11, but this extension is no longer supported?so feel free to skip that part!
This Friday (again at 2pm in A113), we?ll spend the first 30 minutes going over VS Code setup, including settings, keybindings, and useful extensions. The second half will be dedicated to helping with any issues you?re facing, especially related to last week?s topics and the remote SSH setup.
Looking forward to seeing you then!
Cheers,
CCC

Hi all,

Reminder of the CCC in ~1.5hrs, where we'll go over VS Code setup.

If you haven't already, do try to set up remote SSH following Jimi's guide on the GitHub!

See you all there!
Bradley

Subject: CAPT Coding Club (CCC) ? Remote SSH & VS Code Setup for Friday?s Session

Hello Coders,
Thank you to everyone who attended last Friday?s session, where we covered Linux and GitHub, with a brief introduction to VS Code.
Before this Friday?s session, I recommend following Jimi's instructions in the GitHub repo<https://github.com/Bradley-March/capt-coding-club> to try remotely SSHing into Captain/ODHAR using VS Code. If you haven?t used these machines before, please contact Phil to get your account set up. Also, note that the guide mentions Remote X11, but this extension is no longer supported?so feel free to skip that part!
This Friday (again at 2pm in A113), we?ll spend the first 30 minutes going over VS Code setup, including settings, keybindings, and useful extensions. The second half will be dedicated to helping with any issues you?re facing, especially related to last week?s topics and the remote SSH setup.
Looking forward to seeing you then!
Cheers,
CCC

Seminar date: 29 October, Tuesday 1 pm

 Venue: Seminar Room A 113  (Cripps North Building)

  Title:  The Open Effective Field Theory of Inflation

Abstract: There is an increasing interest in the interplay between Open Quantum Systems and Inflationary Physics. A time-dependent background and limited access to the degrees of freedom invites the use of Open Quantum systems. It provides a more general framework than the unitary time evolution of a free state. In this talk, based on https://arxiv.org/abs/2404.15416, we develop a local EFT for the scalar curvature perturbations subject to the dynamics of an open quantum system. We focus on recovering the scale-invariant power spectrum and its amplitude as a function of the dissipation (among other EFT parameters). Our results largely generalize the setup of warm inflation to general non-equilibrium cases. We also explore the different shapes of the bispectrum and find two distinct behaviors, at large and small dissipation.

Wednesday 30th October, B13 Physics at 3pm ? School Colloquium

Harry Cliff (Cambridge)

Rare beauty - the hunt for new physics at the LHCb experiment



When the Large Hadron Collider (LHC) began its physics programme in 2009, there were high hopes that supersymmetric particles, dark matter, micro black holes or other weird and wonderful phenomena would soon be discovered. But despite hundreds of searches performed by thousands of physicists over the past fifteen years, no direct evidence of physics beyond the standard model has been found. However, over the past few years, several intriguing anomalies in the rare decays of beauty quarks have been reported by the LHCb experiment. I will discuss what the causes of these anomalies may be - theory errors, experimental biases or perhaps genuine signs of new physics - and how the recent LHCb upgrade will allow us to zoom in even closer on these tantalising hints.



Refreshments served in C10 after the Colloquium

Hi all,

Matt's viva is on Thursday the 7th of November!

The meal will be at Slice 'n' Brew at 6:30 pm. Since it is quite a small venue, we need to book in advance!

TLDR: If you are coming please send me ?10 (?20 if you have a +1 before Thursday October 31st).

If you would like to come, please fill in this Google form by Thursday October 31st with any dietary requirements and confirm if you require a +1:
https://forms.gle/DJBF67v3mjByjzrCA

If you are coming to Matt's viva meal, the restaurant has asked for a deposit of ?10 per person, which will be taken off the group booking of ?22.50 per person that night.

Please could you send me the ?10 deposit to the following details by Thursday October 31st, at which point I will pay the restaurant. If you have requested a +1, please send me ?20.

Please send the deposit with your full name as a reference:

LAUREN CAITLIN HOWE GAUGHAN (If this is too many characters please enter: MISS L C H GAUGHAN)
40-04-00
11787403

Please be aware that after Thursday October 31st, if you can no longer come to the meal, I will not be able to give your deposit back.

We will be given a party sharing menu where we will be given a selection of pizzas, sides, snacks and dips designed to be shared. This menu is here<https://drive.google.com/file/d/1B1GqXEwXI_rjJs-c8wSTI6T-U4pu2smS/view?usp=drive_link>.

Dear Colleagues,

please excuse the spam, we thought you might be interested in this.

Due to popular demand, our Workshop on Simulation Based Inference for galaxy evolution<https://sbi-galev.github.io/2025/> will take place again in Bristol, 27-30 May 2025. We aim to circulate the first announcement in early December, with abstract submission deadline in February.

For now, save the date, and feel free to get in touch if you would like to get involved in the organisation.

Best wishes,

Subject: [Astro] [CAPT] Misplaced Water Bottle
Message-ID: <AM8PR06MB69464EC505D3F92EDAED6EE5CC552@AM8PR06MB6946.eurprd06.prod.outlook.com>

Hi Everyone,
      I seem to have misplaced my silver metal water bottle (Klean Kanteen brand) with a few stickers (a blue beyond the bottle sticker and a Nightwing logo sticker) on it.  I'm not sure if I left it somewhere in the CAPT building or elsewhere, but thought I'd see if anyone has seen it lying around.  If you do, please let me know or bring it to A108 (my office).

Thanks so much for the help.

Kind regards,
Jesse

Dear Coders,
Thank you to everyone who joined last week?s CCC session on setting up VS Code, especially for configuring it to feel more like Spyder. For those who couldn?t attend, I?ve added a folder to the GitHub repo<https://github.com/Bradley-March/capt-coding-club> <https://github.com/Bradley-March/capt-coding-club> with a basic setup, including JSON files for settings and keybindings. You?ll also find a .md file listing suggested extensions?please let me know if you have additional recommendations, and I?ll be happy to add them.
This week, I won?t be available to lead a session, but A113 is still booked for the usual time. Feel free to gather, share coding tips, troubleshoot issues, or discuss bugs together. Alternatively, if anyone would like to lead a session last-minute, just let me know.
Thanks,
Bradley
CCC
