Our current plan is to go to the Johnson Arms (~10 minute walk from CAPT) for a drink or two, and then get the tram into town to eat at Peter Pizzeria (near the lace market) for around 7pm. It?d be great to have lots of people come along to the pub, especially to help kickstart the old CAPT tradition of pub Friday as we?re welcoming lots of new people to the department over the next few weeks! If you?d also like to come along to the meal, fill out the form here by 2pm tomorrow (Thursday): https://forms.gle/JSYzgDpVtZBi8nLB7 so I have time to call them up and book the table.

In this term, the seminars will be held on Tuesdays at 1pm UK time. In the coming week, we have two visitors, therefore we will be having two seminars (one on Tuesday and one on Thursday). In the following, I provide the details of seminars next week, as well as a list of upcoming seminars for the term. Week: 16/09/2024 - 20/09/2024 ----------------------------------------- 1. Visitor: Andreas Ekstedt (DESY, Hamburg) visiting Oliver Gould for the full week (more details to follow from Oli early next week Seminar date: 17th September, Tuesday, 1 pm Venue: Seminar Room A 113 Title: From EFTs to real-time dynamics and back again Abstract: In this talk I discuss how classical real-time dynamics emerges at high temperatures. In particular I discuss the importance ??????????????of effective-field theory techniques for making accurate predictions in heavy-ion collisions and in various cosmological ???????????????settings. Finally, I discuss how these considerations directly leads to real-time simulations, which in turn allows us to test ???????????????perturbation theory for phase transitions, tunnelling, inflation, and much more. 1. Visitor: Xavier Pritchard (University of Sussex) visiting Clare Burrage and Swagat Mishra for the full week Seminar date: 19th September, Thursday, 3 pm Venue: Seminar Room A 113 Title: Early universe degrees of freedom and primordial black holes Abstract: In this seminar, I will begin by discussing primordial black holes (PBHs). I will walk through a typical abundance calculation, ???????????????which I will hopefully convince the audience is mainly dependent on two early universe quantities: the curvature power ????????????? spectrum and relativistic degrees of freedom. Through this calculation, we will see how the standard model can have an ?????????????? impact on PBH abundances, which I will then try and quantify. In the second part of the seminar (and time permitting), I ????????????? will talk about degrees of freedom beyond the standard model as well as scalar fields, which will be tied back to PBHs.

This will entail some movement of current desks to make space and allow access. Apologies in advance for the disruption this causes, your help and understanding during this process is very much appreciated. Once the rearrangement is complete, any current member of the school is (as always) free to move to an unoccupied desk. Please let me know if you move offices so that I can update the room plan.

The School assures me the tables will be upgraded to actual desks 'at some point'. I've posted a room map on the noticeboard opposite reception. New students will get told to pick an available desk within the office they are assigned to. If anyone would like to move desks / offices, please do so today or tomorrow and if you move office, let me know so that I can update the room allocation. Could everyone also please finish a final tidy up. Unused furniture should go to the greenhouse. Junk should go to the greenhouse. Unoccupied desks should be cleared so that they are obviously vacant when the new people arrive. Given the number of people arriving, could everyone please make an effort to be around for the next couple of weeks so that everyone feels welcome (and so that you can point out which desks are empty and yours doesn't get grabbed).

Speaker: Jeremy Wachter (Wentworth Institute of Technology, Boston) (Online Seminar) Seminar date: 24th September, Tuesday, 1 pm Venue: Seminar Room A 113 Title: Numerical studies of gravitational self-evolution of cosmic string loops Abstract: We present the results of large-scale numerical calculation of how realistic cosmic string loops evolve due to gravitational self-interaction. Initially kinky loops are smoothed, leading to a reduction in the gravitational wave power. However, smoothing never produces strong cusps. Gravitational self-interaction also causes the gravitational wave background from loops to be reduced, more strongly at higher frequencies. We comment on future detectability and other observable impacts, such as loop clustering in galaxies. 1. Speaker: Christian Kading (TU Wien, Vienna) visiting Clare Burrage Seminar date: 26th September, Thursday, 3 pm Venue: Seminar Room A 113 Title: New paths in the search for light scalar fields Abstract: The existence of additional light scalar fields in nature is predicted by many theories in modern physics. In particular, light scalar fields are suggested to play a variety of roles in cosmology and astrophysics. For example, they are frequently considered as candidates for dark matter or dark energy. Consequently, there are continuing experimental and theoretical efforts in searching for light scalar fields. In this talk, we will look at chameleons, symmetrons, and environment-dependent dilatons as prominent examples of so-called screened scalar fields. We will theoretically discuss the use of (open) quantum dynamics and finite-temperature effects as new ways of probing such models. In particular, we will show that some of these previously untaken paths have the potential to put tighter constraints on the parameter spaces of light scalar fields.

The title and abstract are below. Cosmic Carousel of Gas Inflows to the Galactic Nuclei Gas inflows contribute to the evolution of galaxies in a plethora of ways, e.g., by forming stellar substructures in the nuclear regions, feeding AGN and quenching star formation. In barred galaxies, they occur in straight extended shocks along the bar, though these shocks weaken in the central kpc, leaving the dominant driving mechanism for gas inflows in galactic centres not yet fully understood. Shocks persisting over large regions in the inner kpc could cause gas inflow and should be observable as coherent velocity jumps in kinematic maps. With the aid of integral-field unit observations from MUSE on the VLT ? which has a large FoV that maximizes the prospect of finding these coherent structures ?I study ionized gas kinematic maps of the centres of barred galaxies from the Composite Bulges Survey (Erwin et al. 2021) and the TIMER Survey (Gadotti et al. 2019) of nearby galaxies. Using the methodology developed in Kolcu et al. 2023 that involves residual velocity and velocity difference maps, we identify coherent kinematic structures, with the aim to determine the dominant mechanism of inflow in the nuclear regions of galaxies and understand weather this mechanism is analogous to large-scale bar driven inflows. In this presentation, I will briefly introduce the methodology I use, and present our findings for our galaxy sample.

Thanks, Mikey ________________________________ From: Michael Anderson Jennings Sent: 23 September 2024 9:31 AM To: astro at nottingham.ac.uk Subject: Lunch Talk Hi everyone, This week's lunch talk will be given by Tutku on Thursday at 1pm in A113. The title and abstract are below. Cosmic Carousel of Gas Inflows to the Galactic Nuclei Gas inflows contribute to the evolution of galaxies in a plethora of ways, e.g., by forming stellar substructures in the nuclear regions, feeding AGN and quenching star formation. In barred galaxies, they occur in straight extended shocks along the bar, though these shocks weaken in the central kpc, leaving the dominant driving mechanism for gas inflows in galactic centres not yet fully understood. Shocks persisting over large regions in the inner kpc could cause gas inflow and should be observable as coherent velocity jumps in kinematic maps. With the aid of integral-field unit observations from MUSE on the VLT ? which has a large FoV that maximizes the prospect of finding these coherent structures ?I study ionized gas kinematic maps of the centres of barred galaxies from the Composite Bulges Survey (Erwin et al. 2021) and the TIMER Survey (Gadotti et al. 2019) of nearby galaxies. Using the methodology developed in Kolcu et al. 2023 that involves residual velocity and velocity difference maps, we identify coherent kinematic structures, with the aim to determine the dominant mechanism of inflow in the nuclear regions of galaxies and understand weather this mechanism is analogous to large-scale bar driven inflows. In this presentation, I will briefly introduce the methodology I use, and present our findings for our galaxy sample.

Scientific rationale: Clues to a galaxy's past are encoded in its current appearance, and by hunting down these clues, we can infer much about the life histories of these objects. Detailed studies of small numbers of individual systems are complemented by large demographic surveys, and both approaches can be connected to galaxies' high-redshift progenitors. Current cutting-edge instrumentation is being used to obtain a wealth of multi-dimensional information on morphology, kinematics, stellar populations, and gas properties, both within individual galaxies and across the population; the next generation of facilities offers even more exciting possibilities. This conference seeks to bring together experts in the fields of galaxy dynamics, chemical evolution and galaxy environment to discuss recent results, foster collaborative discussion, and understand just how much of a galaxy's past can be inferred from its present-day state. The meeting also honours the careers of Profs. Michael Merrifield and Alfonso Arag?n-Salamanca, who have played important roles in advancing astronomy in this area. Location: The conference will be held in B?zios, a picturesque resort town on a peninsula in Rio de Janeiro, Brazil. B?zios is renowned for its 20 stunning beaches, vibrant nightlife, and the lively Rua das Pedras, filled with boutiques, restaurants, and bars. The town offers a variety of water sports, from snorkeling to surfing, and enjoys a tropical climate with warm temperatures year-round. Easily accessible from Rio de Janeiro, B?zios combines natural beauty with a sophisticated charm. Registration and abstract submission commence on 2nd December 2024.

Speaker: Jeremy Wachter (Wentworth Institute of Technology, Boston) (Online Seminar) Seminar date: 24th September, Tuesday, 1 pm Venue: Seminar Room A 113 Title: Numerical studies of gravitational self-evolution of cosmic string loops Abstract: We present the results of large-scale numerical calculation of how realistic cosmic string loops evolve due to gravitational self-interaction. Initially kinky loops are smoothed, leading to a reduction in the gravitational wave power. However, smoothing never produces strong cusps. Gravitational self-interaction also causes the gravitational wave background from loops to be reduced, more strongly at higher frequencies. We comment on future detectability and other observable impacts, such as loop clustering in galaxies. 1.

The details are given below. 1. Speaker: Dibya Chakraborty (IIT Madras) 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.

Astronomy Seminar Amy Bonsor (IoA, Cambridge) Rocky planets and the potential for life beyond the Solar System 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. --- Thursday 3rd October at 1pm, A113 CAPT ? Astronomy Seminar Arif Babul (Victoria) 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. Thursday 3rd October, A113 CAPT at 3pm ?

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.
