Hello CCC'ers,

The first session of this year's Capt Coding Club will be this Wednesday at 11 am!

We'll start with a quick introduction and the current topic ideas. We can also discuss what we want to use sessions for. If you have some more topic ideas please bring them along or add them in the form below.

The first topic will be a Linux Crash Course. I know most of us use it and know some basics, but it should be nice to go over most of the commands you need when using Linux (and maybe finally understand what they're doing).

Please fill out the form here<https://forms.gle/cwsy1r3BAwCTS4xC6>. It would be nice to know what topics are the most popular. There are also optional sections for topic ideas and volunteering to talk about a topic (this stops you from just hearing from me for weeks on end).

As before, the topics and resources are all on the GitHub repo<https://github.com/Fives555555/capt-coding-club>.

Hope to see you there,
Lauren

Dear all,

Estates appointed contractors will be conducting electrical works within CAPT from Tuesday 7th October to Friday 10th October to rectify some issues discovered during the 5 yearly fixed electrical inspection earlier this year.

A small number of these faults will require short power outages to certain areas of the building, but these will be performed early in the morning to avoid disruption during the working day.  Please therefore ensure that wherever possible you avoid any dependencies upon remote desktop activity next week.

Apologies for any inconvenience this may cause.

Kind regards,

Nick

Write Faster, Think Harder: Surviving Academia in the Age of AI
The rapid integration of generative AI into research practice is transforming the career landscape for postdoctoral researchers (PDRAs) and postgraduate students. Tools such as GPT-5 collapse traditional bottlenecks in coding, data handling, literature review, and drafting, allowing individuals to achieve outputs that previously required larger teams or longer timescales. This shift poses both opportunities and risks. On one hand, researchers who embrace AI critically can accelerate their productivity, explore a wider range of projects, and sharpen originality by offloading routine tasks. On the other, over-reliance risks shallow understanding, loss of craft skills, and exposure when AI outputs are wrong or unexamined.
For early-career researchers, the implications are stark: career progression depends on measurable outputs, and AI adoption is rapidly becoming baseline. Those who resist risk being outpaced; those who adopt without discrimination risk producing volume without depth. Supervisors and institutions therefore face a duty to provide explicit training in critical, reflective AI use ? not banning tools, but teaching researchers how to interrogate, adapt, and own what AI produces. This discussion will consider how PDRAs and postgraduates can position themselves in an AI-rich research environment, where the differentiator is no longer effort but judgement, framing, and insight.

Hi all,

This week?s lunch talk will be given by Frazer Pearce, and will take place on Thursday 2nd October at 1pm in A113. Title and abstract below.

Title: The growth of giants: how brightest cluster galaxies form.

Abstract: The brightest cluster galaxy (BCG) and the surrounding intracluster light (ICL) together dominate the stellar content at the centres of galaxy clusters, but their physical distinction remains blurred. Using hydrodynamical simulations, we investigate the formation of the BCG and ICL components across a sample of massive clusters. First we achieve this via hindcasting, tracking the components we see at z=0 back through cosmic time. We then take what we learned from this process to implement forecasting, allowing us to dynamically split the BCG and ICL components at the current time.  Our results provide motivation for both observational and theoretical attempts to split the BCG from the ICL.

Thanks,
Joe

Title: Lost Beyond ?CDM


Abstract: As cosmological observations reach unprecedented precision, the standard ?CDM model is facing mounting pressure on multiple fronts. The well-known Hubble tension ? a persistent  discrepancy between early- and late-universe determinations of the Hubble constant ? challenges the foundations of our baseline paradigm. At the same time, recent Baryon Acoustic Oscillation measurements from DESI suggest bounds on the sum of neutrino masses that increasingly conflict with lower limits from particle physics, assuming standard cosmology. Extensions to the dark energy sector, particularly evolving dark energy models, can alleviate the neutrino mass tension and even appear to disfavor a cosmological constant at ~3-4?. Yet these scenarios generally fail to address the Hubble tension. Conversely, both early- and late-time solutions proposed for the Hubble tension often drive the neutrino mass toward unrealistically small values, worsening the conflict with particle physics. This raises a natural question: is a coherent framework capable of reconciling all datasets still within reach, or is the cosmological blanket simply too short, such that pulling to cover one discrepancy inevitably leaves another exposed? In this talk, I will explore the web of tensions currently plaguing modern cosmology, and outline possible pathways into the beyond-?CDM landscape.

The Metallicity of the ICL: A Euclid Q1 Story

Colour provides key information for constraining the stellar population of the intracluster light (ICL), the diffuse light within galaxy clusters. Using the Euclid Q1 photometry for 174 DES-redMaPPer galaxy clusters (within the Q1 footprint) over the redshift range 0.1 < z < 0.75, we derive radial colour profiles of the brightest central galaxy (BCG) and ICL. Using elliptical annuli, we detect a colour gradient, such that the ICL is bluer than the BCG. By stacking these profiles, we can extend this gradient out to 600kpc. Using stellar population synthesis models, we find that near infrared colours are sensitive to metallicity, not age. Thus, we measure a metallicity gradient in the BCG+ICL out to 600kpc for the first time. We find that the metallicity of the BCG, which moderately evolves with redshift, is super-solar [log10 (Z/Zsun) > 0.2], while the ICL is metal-poor [log10(Z/Zsun)\sim -0.5 to -1.0], placing the first statistical constraint on the metallicity of the ICL as a population out to large radii. These results support our current understanding of BCG and ICL formation: BCGs form predominantly through mergers with massive galaxies or the cores of satellite galaxies, while the ICL grows via the tidal stripping of lower metallicity stars from the outskirts of massive satellite galaxies.

Hi Everyone,
      I hope that you are all doing well.  This week, we will be having our department Jamboree!  This is our yearly tradition of getting to know everyone in the department.


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 (Jesse) the photos by Tuesday (October 7th).  As of now, I only have slides from 8 people, so please do send them soon.  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, that way everyone can still get to know you!).


Also, on Tuesdays, October 7th and October 14th, at 13:00 in A113, there will be join Astro-Particle seminars.  This week's seminar is from William Giare (Sheffield).  The title and abstract are provided below.

Title: Lost Beyond ?CDM



Abstract:

As cosmological observations reach unprecedented precision, the standard ?CDM model is facing mounting pressure on multiple fronts. The well-known Hubble tension ? a persistent  discrepancy between early- and late-universe determinations of the Hubble constant ? challenges the foundations of our baseline paradigm. At the same time, recent Baryon Acoustic Oscillation measurements from DESI suggest bounds on the sum of neutrino masses that increasingly conflict with lower limits from particle physics, assuming standard cosmology. Extensions to the dark energy sector, particularly evolving dark energy models, can alleviate the neutrino mass tension and even appear to disfavor a cosmological constant at ~3-4?. Yet these scenarios generally fail to address the Hubble tension. Conversely, both early- and late-time solutions proposed for the Hubble tension often drive the neutrino mass toward unrealistically small values, worsening the conflict with particle physics. This raises a natural question: is a coherent framework capable of reconciling all datasets still within reach, or is the cosmological blanket simply too short, such that pulling to cover one discrepancy inevitably leaves another exposed? In this talk, I will explore the web of tensions currently plaguing modern cosmology, and outline possible pathways into the beyond-?CDM landscape.




In peace,

Hi all,

This week?s lunch talk will be given by Jesse Golden-Marx, and will take place on Thursday 9th October at 1pm in A113. Title and abstract below.

Title: The Metallicity of the ICL: A Euclid Q1 Story

Abstract: Colour provides key information for constraining the stellar population of the intracluster light (ICL), the diffuse light within galaxy clusters. Using the Euclid Q1 photometry for 174 DES-redMaPPer galaxy clusters (within the Q1 footprint) over the redshift range 0.1 < z < 0.75, we derive radial colour profiles of the brightest central galaxy (BCG) and ICL. Using elliptical annuli, we detect a colour gradient, such that the ICL is bluer than the BCG. By stacking these profiles, we can extend this gradient out to 600kpc. Using stellar population synthesis models, we find that near infrared colours are sensitive to metallicity, not age. Thus, we measure a metallicity gradient in the BCG+ICL out to 600kpc for the first time. We find that the metallicity of the BCG, which moderately evolves with redshift, is super-solar [log10 (Z/Zsun) > 0.2], while the ICL is metal-poor [log10(Z/Zsun)\sim -0.5 to -1.0], placing the first statistical constraint on the metallicity of the ICL as a population out to large radii. These results support our current understanding of BCG and ICL formation: BCGs form predominantly through mergers with massive galaxies or the cores of satellite galaxies, while the ICL grows via the tidal stripping of lower metallicity stars from the outskirts of massive satellite galaxies.

Thanks,
Joe

Hi Everyone,
      Next week's seminar speaker is Jame Nightingale, former Nottingham alum.  He'll be visiting from Newcastle and spending the day in Nottingham.  There will be a dinner with him at Sanchans Thai restaurant in Beeston (https://www.sanchans.co.uk<https://www.sanchans.co.uk/>).  Time is TBD (but after wine and cheese). If anyone is interested in joining, please let me know by Monday.  Additionally, James will be arriving early enough to join for lunch, so if you're interested in joining for that (we can sponsor a few postgraduates), please let me know about that by Tuesday as well.

I'll send around all of the rest of this information next week, I just wanted to give anyone a heads up about joining for the dinner.

Cheers,
Jesse

Title: Connecting primordial physics to cosmological observables through simulations


Abstract: Cosmology is entering a golden era with the coming decade bringing a wealth of multiwavelength observations of the cosmos. Unfortunately, relating these precision observations to the sought after primordial processes is complex due to the non-linear processes that have governed the evolution of the universe. In this talk I will describe the role that cosmological simulations can play in untangling primordial signals from late-time astrophysical processes. These approaches will shed new light on aspects from the number of fields present during inflation to the strength of interactions to symmetries of inflation. I will conclude by describing ongoing efforts to combine these approaches with new measurements, such as those by the Atacama Cosmology Telescope and Simons Observatory.

Connecting primordial physics to cosmological observables through simulations


Cosmology is entering a golden era with the coming decade bringing a wealth of multiwavelength observations of the cosmos. Unfortunately, relating these precision observations to the sought after primordial processes is complex due to the non-linear processes that have governed the evolution of the universe. In this talk I will describe the role that cosmological simulations can play in untangling primordial signals from late-time astrophysical processes. These approaches will shed new light on aspects from the number of fields present during inflation to the strength of interactions to symmetries of inflation. I will conclude by describing ongoing efforts to combine these approaches with new measurements, such as those by the Atacama Cosmology Telescope and Simons Observatory.

Supermassive Black Holes, Galaxies and Dark Matter with Strong Gravitational Lensing


In a strong gravitational lens, a background source galaxy appears multiple times, because its light is deflected by an intervening foreground galaxy?s mass. Lens modeling reverses the source galaxy?s deflected emission and reconstructs the foreground lens?s projected gravitational potential at an unprecedented level of detail, providing Astronomer?s with a powerful tool to study the Universe. I present the first measurement of a supermassive black hole (SMBH) mass using strong lensing, detecting a $\log_{10}(M_{\text{BH}}/M_{\odot}) = 3.27 \pm 2.12 \times 10^{10}$ SMBH in the $z = 0.451$ lens Abell 1201. I discuss the potential for lensing to measure additional SMBH masses and its implications for black hole demographics. I then explore how strong lensing enhances traditional studies of galaxy structure, revealing complex features such as boxiness, diskiness, asymmetric twists, lopsidedness, and stellar-to-dark matter offsets?features that challenge our current understanding of galaxy formation. Finally, I demonstrate how unseen dark matter substructures perturb lensed emission, providing a unique opportunity to test different dark matter models, provided that we can overcome limitations in our knowledge of galaxy mass distributions.

Julian Onions
What will I be when I grow up?


Do high redshift clusters grow in a predictable way? Can we estimate how big something will be that is big at early times? In this talk I'll show why this is not necessarily the case, and that we have to be a little more cautious about predicting cluster size from their beginnings. After a few years - this project finally came to a conclusion, so I will recap what we found.

Subject: Invitation to RAS Public Policy event, 21 October



Dear RAS Point of Contact,



As you know, the RAS has a longstanding commitment to public policy and advocacy in support of our sciences, namely astronomy, space science and geophysics. To that end, we regularly engage with elected politicians, civil servants and others in support of our aims, commission quantitative research and make statements to the press.



We are now reviewing our public policy priorities to help shape our activity over the next few years. It is of the utmost importance to us that these are based on input from our Fellowship as well as taking account of external drivers. A small group of trustees has helped us with this at the outset, and we would now like to invite you to attend a workshop at the RAS offices in Burlington House on Tuesday 21st October from 10.30am to 12.30pm to help us develop these and a work plan for the Society.



The workshop will be in person and limited to 20 participants, and will be free to attend with catering provided.



If you or a colleague in your research group would like to come along, we are offering places on a first come first served basis, so please register using the following link: https://www.eventbrite.co.uk/e/in-person-workshop-on-the-ras-public-policy-priorities-tickets-1757820982879?aff=oddtdtcreator

Supermassive Black Holes, Galaxies and Dark Matter with Strong Gravitational Lensing



In a strong gravitational lens, a background source galaxy appears multiple times, because its light is deflected by an intervening foreground galaxy?s mass. Lens modeling reverses the source galaxy?s deflected emission and reconstructs the foreground lens?s projected gravitational potential at an unprecedented level of detail, providing Astronomer?s with a powerful tool to study the Universe. I present the first measurement of a supermassive black hole (SMBH) mass using strong lensing, detecting a $\log_{10}(M_{\text{BH}}/M_{\odot}) = 3.27 \pm 2.12 \times 10^{10}$ SMBH in the $z = 0.451$ lens Abell 1201. I discuss the potential for lensing to measure additional SMBH masses and its implications for black hole demographics. I then explore how strong lensing enhances traditional studies of galaxy structure, revealing complex features such as boxiness, diskiness, asymmetric twists, lopsidedness, and stellar-to-dark matter offsets?features that challenge our current understanding of galaxy formation. Finally, I demonstrate how unseen dark matter substructures perturb lensed emission, providing a unique opportunity to test different dark matter models, provided that we can overcome limitations in our knowledge of galaxy mass distributions.

Hi all,

This week?s lunch talk will be given by Julian Onions, and will take place on Thursday 16th October at 1pm in A113. Title and abstract below.

Title: What will I be when I grow up?

Abstract: Do high redshift clusters grow in a predictable way? Can we estimate how big something will be that is big at early times? In this talk I'll show why this is not necessarily the case, and that we have to be a little more cautious about predicting cluster size from their beginnings. After a few years - this project finally came to a conclusion, so I will recap what we found.

Thanks,
Joe

Next week on Wednesday, we have Dr. Tim Pearce from the University of Warwick for the seminar.
Please find his talk abstract below.

Title: Extrasolar Kuiper Belts

Abstract: Our Solar System contains not only planets, but also many smaller bodies, like asteroids and comets. These bodies are collectively called 'debris', and they tend to  be concentrated in 'debris discs' like the Asteroid Belt and Kuiper Belt. We can image extrasolar Kuiper Belts around other stars too, and these belts exhibit a broad diversity of shapes and features. These shapes are often attributed to interactions with unseen exoplanets. In this talk I give a broad overview of debris discs, including observations, dynamics and evolution. I also explain what debris discs teach us about exoplanets and their historical evolution, and outline what the biggest outstanding questions are. For this talk I assume no prior knowledge, and try to make it accessible to a wide range of seniorities and experience levels.
*****

We will have our usual schedule: going for lunch around 13:00, ?Meet the Speaker? is at 15:00 (in A113) and the talk starts at 15:45 (in Physics Building, C4). The day will be followed by wine and cheese, and most importantly grapes and grape scissors.

If you wish to join the lunch, let me know. Also, if anyone wants to have a chat with the speaker during the day, I am more than happy to arrange this for you.

Best
Luke, Jesse and Tutku

Title: Fundamental and beyond-standard-model physics from CMB-electron scattering


Abstract:  As the CMB travels through the Universe, it interacts with large-scale structure, including with the inhomogeneous electron gas that surrounds galaxies. The Compton-scattering of the CMB off these electrons leads to the Sunyaev--Zel'dovich effect. This induces new CMB anisotropies, which carry information about the distribution of electrons, and gives us access to a new cosmological probe: their large-scale velocity. We can access this information with state-of-the-art high-resolution CMB surveys such as ACT and SO. I will talk about how the SZ effect in combination with a galaxy survey will constrain fundamental and beyond-standard-model physics, focusing on probes of inflation.  I will also talk about more exotic CMB-electron interactions and recent constraints on beyond-standard-model particle physics, focusing on dark photon-CMB and axion-CMB interactions.

These bodies are collectively called 'debris', and they tend to  be concentrated in 'debris discs' like the Asteroid Belt and Kuiper Belt. We can image extrasolar Kuiper Belts around other stars too, and these belts exhibit a broad diversity of shapes and features. These shapes are often attributed to interactions with unseen exoplanets. In this talk I give a broad overview of debris discs, including observations, dynamics and evolution. I also explain what debris discs teach us about exoplanets and their historical evolution, and outline what the biggest outstanding questions are. For this talk I assume no prior knowledge, and try to make it accessible to a wide range of seniorities and experience levels.

Hi all,

This week?s lunch talk will be given by Jack Terry, and will take place on Thursday 22nd October (tomorrow) at 1pm in A113. Title and abstract below.

Title: Morphological Indicators of Galaxy Interactions with Galaxy Zoo DESI

Abstract: In their 2013 paper, 'Galaxy Zoo: quantifying morphological indicators of galaxy interaction'<https://academic.oup.com/mnras/article/429/2/1051/1034562> , the authors Casteels et al. used data from Galaxy Zoo 2 to search for morphological indicators of tidal interactions between pairs of galaxies, and identified a number of morphological features that correlated with pair separation. Since then, newer surveys have provided higher resolution and more sensitive images of large numbers of galaxies, while machine learning has allowed for efficient labelling of larger catalogues. In this talk, I will describe some of my work to reproduce and update the method given by Casteels et al. using more recent morphology data from Galaxy Zoo DESI.

Thanks,
Joe

Postdoctoral Prize Fellowship and Postdoctoral Positions in the Galaxies and Cosmology Department at MPIA

The Max Planck Institute for Astronomy (MPIA) in Heidelberg plans to offer up to 10 postdoctoral positions for pursuing innovative theoretical or observational research within the Galaxies and Cosmology department. The department?s research covers a wide range of topics related to galaxy evolution from the stars in the Milky Way to the highest redshift quasars: stellar spectroscopy as a diagnostic for stellar physics and Galactic archeology; star formation and the interstellar medium in galaxies near and far; galactic nuclei, black holes, and AGN; the redshift evolution and physical properties of the galaxy population and of the circumgalactic, intracluster and intergalactic medium, as well as studies of the most distant galaxies, quasars and galaxy clusters.

Our research approaches encompass multi-wavelength observations, large surveys and large observing programs, e.g., Gaia, JWST, Euclid, Rubin Observatory/LSST, SDSS-V and 4MOST. We also pursue large simulation projects (e.g., IllustrisTNG, TNG-Cluster), as well as innovative instrumentation development (e.g., MICADO for the ELT). Finally, the department hosts several independent research groups supported by the Max Planck Society and the ERC.

We invite applications for our independent 4-year prize fellowship and for a number of topic or project-related positions detailed here: www2.mpia-hd.mpg.de/~gc_jobad/gc_25-403.html.

Applications for the latter positions can also be considered for the fellowship.

Applicants should have a Ph.D. in astronomy, astrophysics, or a closely related field. The starting dates are expected to be no later than fall 2026; earlier dates may be possible for certain positions.
------------------------------------------------------------------------------


The International Max Planck Research School for Astronomy & Cosmic Physics at the University of Heidelberg (IMPRS-HD)


We welcome applications of students from all countries. Successful candidates will be selected based on their excellence as proven by their university record, their research experience and their letters of recommendation.

A selection committee composed of members from all participating astronomy institutes and the university Department of Physics and Astronomy will review the applications and will advice potential supervisors about the qualification of the candidates.
The final decision to offer a thesis project to an applicant is made by the supervisor of that project and will be communicated to the applicant by IMPRS-HD.
Students are admitted to the IMPRS-HD once per year. The school program starts September each year. However, an earlier start of the actual PhD research work is possible, depending on the funding for the project. We call for applications each summer for the academic program starting the year after.
Application deadline for the academinc year starting fall 2026 is November 1, 2025, at 23:59 CET.

Dear all,

I have been asked by the School colloquium organiser (Kay Brandner) to provide a few suggestions for possible School-wide colloquium speakers. They need to be people who are good speakers and can talk to an audience of non-astronomers on a topic that would interest Physicists also. The way it works is that the group proposing somebody has to fund their travel and accommodation, so if somebody suitable is visiting, even better (if not we can fund them from the astronomy seminar budget, or from individual grants if available).

Please send me any suggestions you may have with name and contact details and I will pass them to Kay. We don't need many, but we need good ones!

Thanks.

Best wishes,

Title: Atomic and molecular transitions for neutrino and light dark

matter detection


Abstract:  The detection of light, cold, and weakly interacting relics

from the early universe is an extraordinary challenge. In this talk, I
will discuss the possibility of using atoms and molecules as relic
neutrino and dark matter detectors. I will begin with a brief
introduction to generalised atomic interactions, and then discuss our
recent progress: CINCO, an automated tool for the computation of atomic
transition amplitudes, and pair absorption, which is particularly
sensitive to light, bosonic dark matter. Time allowing, I will then
move on to discuss our current work using molecules and crystals.

Oliver Buchmueller (Imperial)

Exploring the Universe with Quantum Technology: A New Frontier in Fundamental Physics



Recent advances in cold-atom quantum technology are opening an unprecedented window on the Universe.  Professor Oliver Buchmueller will show how these sensors are now addressing some of the most fundamental questions in physics. This technology enables ultra-sensitive gravitational-wave detection in the mid-frequency band, filling the crucial gap between LISA and ground-based observatories (LIGO, Virgo, KAGRA, INDIGO, Einstein Telescope, and Cosmic Explorer), while advancing multiple frontiers in fundamental science. Applications include dark-matter searches, studies of intermediate-mass black-hole mergers, and investigations of early-universe cosmology.


The talk will introduce the UK?s Atom Interferometer Observatory and Network (AION) and the newly established Terrestrial Very-Long-Baseline Atom Interferometry (TVLBAI) proto-collaboratio - an international initiative targeting kilometre-scale detectors by the mid-2030s. Combined with proposed space missions such as AEDGE, these efforts herald a new scientific era in which quantum instruments probe gravitational phenomena, dark matter, cosmology, and the architecture of space-time itself.

Tracing the invisible: The shape of cluster haloes revealed by intracluster light



 The intracluster light (ICL) provides a powerful means of tracing the diffuse stellar component of galaxy clusters and directly probing the shapes of their underlying dark matter haloes. The morphology of the ICL?its ellipticity, orientation, and radial variation?encodes valuable information about cluster assembly, dynamical state, and the coupling between baryons and dark matter. However, its extremely faint nature has long hindered systematic studies of structure on cluster scales. With the advent of high-resolution, wide-field imaging from Euclid, we can now measure ICL shapes with unprecedented precision. In this talk, I will present results from Euclid?s Quick Release (Q1), where we quantify ICL ellipticity and position angle for nearly 200 clusters between redshifts 0.1 and 0.8 across five photometric bands (VIS, Y, J, H, and coadded YJH). We find consistent shape parameters across filters, with the H band tracing the ICL to the largest cluster-centric distances. The ICL becomes progressively more elongated with radius, reaching ellipticities consistent with those inferred from weak and strong lensing studies, and showing alignment with both the brightest cluster galaxy and the member galaxy distribution. Comparisons with Hydrangea hydrodynamical simulations reveal similar, though slightly rounder, ICL shapes. These results establish the ICL as a robust luminous tracer of halo structure and orientation.

A relational description of cosmological spacetimes as hydrodynamic systems



In this talk we introduce a new framework called "hydrodynamics on minisuperspace" where cosmology is viewed as an effective, coarse-grained description of an underlying fundamental quantum theory. After giving some motivation, we present a map between hydrodynamics and standard cosmology, which is based on dynamical equations and symmetry arguments. Such a map can only be achieved by means of relational observables defined with no reference to a spacetime manifold (i.e., on minisuperspace). We also comment on the Group Field Theory (GFT) approach to quantum gravity, which realises precisely these ideas by describing the emergence of spacetime by a ?condensate? of more fundamental degrees of freedom. We conclude mentioning recent results that describe Bogolyubov excitations in GFT and hence beyond mean-field corrections.

Hi all,

This week?s lunch talk will be given by Tutku Kolcu, and will take place on Thursday 30th October at 1pm in A113. Title and abstract below.

Title: Tracing the invisible: The shape of cluster haloes revealed by intracluster light

Abstract: The intracluster light (ICL) provides a powerful means of tracing the diffuse stellar component of galaxy clusters and directly probing the shapes of their underlying dark matter haloes. The morphology of the ICL?its ellipticity, orientation, and radial variation?encodes valuable information about cluster assembly, dynamical state, and the coupling between baryons and dark matter. However, its extremely faint nature has long hindered systematic studies of structure on cluster scales. With the advent of high-resolution, wide-field imaging from Euclid, we can now measure ICL shapes with unprecedented precision. In this talk, I will present results from Euclid?s Quick Release (Q1), where we quantify ICL ellipticity and position angle for nearly 200 clusters between redshifts 0.1 and 0.8 across five photometric bands (VIS, Y, J, H, and coadded YJH). We find consistent shape parameters across filters, with the H band tracing the ICL to the largest cluster-centric distances. The ICL becomes progressively more elongated with radius, reaching ellipticities consistent with those inferred from weak and strong lensing studies, and showing alignment with both the brightest cluster galaxy and the member galaxy distribution. Comparisons with Hydrangea hydrodynamical simulations reveal similar, though slightly rounder, ICL shapes. These results establish the ICL as a robust luminous tracer of halo structure and orientation.

Thanks,
Joe

Managing your email storage ? what?s changing
[X]
Scott Williams (staff)
Engagement & Communication Specialist

Following a successful pilot within Digital Technology Services, we are making changes to email storage in Microsoft Outlook to mitigate increases in M365 storage costs. These changes are designed to help you proactively manage your mailbox while ensuring important emails continue to be safely stored.

What is changing?



Email archiving



  *   Every staff member will have an Online Archive mailbox created automatically (this does not apply to shared mailboxes).
  *   Emails older than 90 days will be moved automatically into your archive. This helps keep your main mailbox lighter and faster. The process will take a few days to complete, but emails will continue to be available and no action is required from you.
  *   Your archive mirrors your current folder structure, so you will find your emails organised just as before. In the Outlook app, it will appear as: ?Online Archive ? [Your Name]? and in the web version as ?In-Place Archive [Your Name}?.
  *   You can still move emails into the archive manually if needed.
  *   Archived emails will also appear in your Outlook searches, so you can find them quickly alongside your current mailbox.
  *   The archive is available across Outlook Web, New Outlook, desktop (Windows/Mac) and mobile apps. Please note: some third-party email applications may display archives differently.

Deleted items



  *   Emails in your Deleted Items folder will be permanently deleted after 90 days.
  *   You can still restore deleted emails during this 90-day period.
  *   This change aligns email deletion with how files are managed in OneDrive and SharePoint.

Tip: Only delete emails you no longer need to keep your mailbox tidy.

Calendar archive



Archived calendars



Once online archiving is applied to your email account, an archive version of your calendar will also be created. This archive calendar contains appointments that are over 90 days old, while your ?live? mailbox calendar continues to show:

  *   All future appointments (coming days, weeks, and months)

  *   All appointments from the past 90 days

  *   All recurring appointments from the date they were created

Accessing archived calendars



Archived calendars are currently only visible via the classic version of the Outlook desktop app ? not in New Outlook or the web version.

To view the archive calendar, go to:

My Calendars ? Calendar ? Online Archive ? [your email address]

This will include archive versions of any additional calendars you have added (shared, room, or colleagues? calendars), regardless of whether archiving has been applied to them.



[cid:f79df2e4-bfd9-4614-aaa1-28469df15b2d]
What you will see in your archive calendar



The archive calendar only shows appointments from over 90 days ago. When selected, it may appear empty ? simply navigate to a date more than 90 days in the past to view older entries.

Why these changes matter



  *   The changes are an important step to mitigate increases in M365 storage costs without deleting anything important.

  *   Older emails are safely archived, so you can search and access them at any time.

  *   Your day-to-day email use won?t change.

Support and feedback



We are expecting to roll this out over the next 2 months, and DTS is here to support you every step of the way:

  *   If you need help accessing your archive or recovering emails, contact the IT Service Desk<https://www.nottingham.ac.uk/dts/help/it-support.aspx>.

  *   We value your feedback on how these changes impact your workflow, your input helps us continue to improve. Please contact us at UI-DTS-Datastorage at nottingham.ac.uk<mailto:UI-DTS-Datastorage at exmail.nottingham.ac.uk>
