We show that the screening mechanism of the asymmetron inside dense objects induces a surface tension associated with the boundary of the screening object, leading to a richer class of bubble solutions than the standard Coleman-Callan bulk nucleation. These boundary surface tensions are used to modify the Nambu-Goto action for instantons, allowing for the computation of the corresponding Euclidean action for bubbles nucleating on flat planes, as well as on concave and convex cylindrical surfaces. We find that the smallest Euclidean action occurs for bubbles nucleating along the edge of a concave spherical surface. Comparing this edge nucleation channel with the bulk one, we determine the maximum curvature radius for which concave edge nucleation is preferred. Since the maximum radius of curvature is exponentially suppressed by the action of a bulk bubble, we find that within the regime of the instanton approximation, edge nucleation is always preferred. This is largely due to the weak couplings of the asymmetron. We apply these findings to determine the maximum curvature radius of a cosmic void and discuss how our results affect the seeding of N-body simulations of asymmetron domains, showing that domain wall nucleation preferentially occurs at the edges of cosmological voids. We also demonstrate that the presence of a homogeneous gas around the dense substrates reduces the maximum curvature radius, enabling bulk bubbles to form preferentially as the asymmetron undergoes a density-driven phase transition. -------------------------------------------------- Link to join: https://teams.microsoft.com/l/meetup-join/19%3ameeting_OGM3OTk5NzQtZWEwZS00ZmUyLTk3MGUtZjFhY2M5OTU2MjI1%40thread.v2/0?context=%7b%22Tid%22%3a%2267bda7ee-fd80-41ef-ac91-358418290a1e%22%2c%22Oid%22%3a%22f3250584-4b5f-48fa-a897-08e77f2246b7%22%7d List of upcoming Seminars: Nov 11th:?Sotirios Karamitsos (Tartu U.)

Cheers, Jesse, Luke, and Tutku How massive galaxies quench in the Simba simulations Cosmological simulations of galaxy formation have matured rapidly in the last few years, with recent models combining structure formation, hydrodynamics, stellar and black hole growth, and associated feedback processes to accurately reproduce key demographical properties observed in the galaxy population. Our group's Simba simulation suite includes unique input physics that have dramatic implications particularly for the growth and quenching of massive galaxies. I will show how Simba's AGN jet feedback impacts the surrounding circum-galactic and intergalactic medium on surprisingly large scales. Using the Hyenas zoom simulations based on Simba, I will further show how Simba's jets blow X-ray cavities as observed, depositing energy and evacuating halo gas, the first time this has been demonstrated within a full hierarchical galaxy formation context. Such feedback also goes helps explain some puzzling trends seen in the stellar-to-halo mass relation and the matter power spectrum.

Title: Minding the Gap Between Scales: Insights from Simulations on the Role of Local Density and the Cosmic Web on Galaxy Evolution Abstract: The evolution of galaxies is strongly influenced by their surrounding environment, from the local density of neighbouring systems to their position within the cosmic web. In this work, we aim to disentangle the relative importance of these factors using simulated galaxies. Building on the observational framework of O?Kane et al. (2024), we classify simulated galaxies into six environmental categories to explore how their baryonic properties and star formation activity vary with local density and cosmic-web location. As a first step, we focus on two test clusters from The Three Hundred project. We examine the spatial distribution of their galaxies and the stellar mass function in each environment. We will later incorporate star formation rates and compare different density estimators. Future stages will include contrasting results between hydrodynamical (GIZMO?SIMBA) and semi-analytic (SAG) models, and evaluating the impact of different filament identification methods. This ongoing work will provide new insights into how local and large-scale structures jointly drive galaxy evolution.

Title and abstract below. Title: Minding the Gap Between Scales: Insights from Simulations on the Role of Local Density and the Cosmic Web on Galaxy Evolution Abstract: The evolution of galaxies is strongly influenced by their surrounding environment, from the local density of neighbouring systems to their position within the cosmic web. In this work, we aim to disentangle the relative importance of these factors using simulated galaxies. Building on the observational framework of O?Kane et al. (2024), we classify simulated galaxies into six environmental categories to explore how their baryonic properties and star formation activity vary with local density and cosmic-web location. As a first step, we focus on two test clusters from The Three Hundred project. We examine the spatial distribution of their galaxies and the stellar mass function in each environment. We will later incorporate star formation rates and compare different density estimators. Future stages will include contrasting results between hydrodynamical (GIZMO?SIMBA) and semi-analytic (SAG) models, and evaluating the impact of different filament identification methods. This ongoing work will provide new insights into how local and large-scale structures jointly drive galaxy evolution.

There are many realizations of pole inflation, from elementary particle theory and supersymmetry to modified gravity scenarios. We focus on a very general class of metric-affine F(R) gravity models that incorporate all even-parity quadratic invariants of torsion and non-metricity. The resultant theory is found to be equivalent to a metric theory with a single scalar degree of freedom with a non-canonical kinetic term that features poles. Such poles in the framework of pole inflation are known to dominate the inflationary dynamics such that the predictions of the model are insensitive to the details of the potential as determined here by F(R). We analyse a simplified version of the model analytically as well as the full eleven-parameter theory numerically. We outline conditions that allow for consistent pole inflation: the presence of second-order poles as well as freedom from ghosts, and we additionally check whether specific choices of parameters predict a sufficiently small tensor-to-scalar ratio. We find that by relaxing the ghost-free requirement to only exclude ghosts near the pole, the region of viable models in parameter space is greatly enhanced, leading to a robust class of models for inflation that faithfully reproduces the attractor predictions. -------------------------------------------------- Link to join: https://teams.microsoft.com/l/meetup-join/19%3ameeting_OGM3OTk5NzQtZWEwZS00ZmUyLTk3MGUtZjFhY2M5OTU2MjI1%40thread.v2/0?context=%7b%22Tid%22%3a%2267bda7ee-fd80-41ef-ac91-358418290a1e%22%2c%22Oid%22%3a%22f3250584-4b5f-48fa-a897-08e77f2246b7%22%7d List of upcoming Seminars: Nov 18th: Benjamin Muntz (Nottingham) Nov 25th:?Fraser Cowie (Oxford) Dec 2nd: Violetta Sagun (Southampton) Dec 9th: James Alvey (Cambridge) -------------- next part -------------- An HTML attachment was scrubbed...

Best, Jesse, Tutku and Luke == Small-scale structure in cold dark matter: from ultra-faint dwarfs to prompt cusps In our present paradigm of galaxy formation, the onset of structure is brought about via the gravitational collapse of (cold) dark matter, which subsequently acts as the scaffolding for the visible universe. A vigorous programme of numerical simulations has established several features of the dark matter model: the formation of haloes, and how their structure and abundance is influenced by the particle physics of the underlying model. The smallest visible galaxies?so-called ?ultra-faint dwarfs??are fossil records of an early phase of galaxy formation in the Universe and their assembly provides strong clues into the Epoch of Reionisation, galactic feedback, and the nature of the dark matter particle. Yet, the cold dark matter model predicts the formation of structure many orders-of-magnitude below the scale where galaxy formation ends, where individual dark matter haloes have masses comparable to that of the Earth. In this talk, I will discuss some of the progress we have made in understanding this regime using numerical simulations, and what their implications are for understanding the physics of galaxy formation, the nature of dark matter, and our prospects for detecting dark matter in the future. _______________________________________________ CAPT mailing list CAPT at lists.nottingham.ac.uk https://lists.nottingham.ac.uk/mailman/listinfo/capt From Joseph.Butler at nottingham.ac.uk Mon Nov 10 12:14:25 2025 From: Joseph.Butler at nottingham.ac.uk (Joseph Butler) Date: Mon, 10 Nov 2025 12:14:25 +0000 Subject: [Astro] Lunch Talk & Visitor - 13/11/25 Message-ID: <8799F9A9-CD8C-4FF0-B110-5C454B93D88F@nottingham.ac.uk> Hi all, This Thursday (13/11/25), we will be visited by Andr?s Ponte Perez, a third year PhD student from the University of Birmingham, whose research concentrates on gravitationally lensed explosive transients, including core collapse supernovae. He will be giving the lunch talk at 1pm (title and abstract below). We might go for lunch in Portland either before or just after the talk, so if you?re interested in joining let me know. Title: Gravitationally Lensed Type IIn Supernovae in the LSST era Abstract: Over the next decade, large surveys, such as Rubin Observatory's Legacy Survey of Space and Time (LSST), are expected to yield hundreds to thousands of detections of gravitationally lensed supernovae, offering unprecedented advances in the study of these phenomena. Of particular note is the expected prevalence of Type IIn supernovae, which, with ~50 detections expected per year, dominate the predicted detection rates among lensed transients. This is despite making up only 5-10% of the local observed non-lensed core-collapse supernova population. In this talk, I will discuss why Type IIn supernovae are uniquely suited for detections when gravitationally lensed. I will explore the properties of the predicted population of detections and what we might be able to learn and infer from this population about the terminal stages of massive stars across cosmic time. I will also discuss the prospects of performing spectroscopic follow-up, how gravitational lensing might provide a novel means to improve the time precision of the spectroscopic time series of these supernovae, and the powerful implications of high-cadence spectroscopy for the study of circumstellar interaction in supernovae.

Please find his talk abstract below. ***************** Multi-Scale Pathways to Galaxy Quenching The big evolutionary change in the life of a galaxy is its transition from a star-forming to a passive state. In this talk, I will discuss several possible physical mechanisms that can induce this transition, each acting in a different regime of galaxy mass and/or large-scale environment. I will discuss how satellite galaxies may lose gas as they slam into the hot medium characterising massive haloes, how massive galaxies may be limited by their ability to accrete gas from the large-scale environment, and how intermediate-mass galaxies may fail to retain their gas after internal explosions. I will describe new progress on each of these mechanisms but highlight the puzzles that stand in the way of a complete understanding. Ultimately, I?ll discuss how new wide-field surveys will deliver answers to these puzzles. ***************** The seminar will be in the Physics Building C4 at 15:45, followed by the wine and cheese in the usual place.

The second will be in our usual 1pm slot on Thursday (20/11/25) in A113, and will be given by Helen Russell. Title and abstracts for both are below. --- Monday 17/11/25 - Esin Gulbahar Title: The SIXTE Simulator Abstract: SIXTE (Simulation of X-ray Telescopes) is a modular end-to-end software package for X-ray telescope observation simulations developed at the Remeis Observatory (ECAP). It allows to undertake instrument performance analyses and to produce simulated event files for mission and analysis studies. The software simulates the full detection chain from the astrophysical source through imaging and detection while finding a balance between exactness of the simulation and speed. For many cases, by using calibration files such as the PSF, RMF and ARF, efficient simulations are possible at comparably high speed, even though they include nonlinear effects such as pileup. In this talk I will give an introduction to the software, while demonstrating example usage of SIXTE in High Energy Astrophysics. --- Thursday 20/11/25 - Helen Russell Title: XRISM's first results Abstract: The X-ray Imaging and Spectroscopy Mission (XRISM) was launched by JAXA and NASA in late 2023. XRISM carries onboard the next generation of X-ray instrumentation - the X-ray microcalorimeter. With nearly two orders of magnitude improvement in spectral resolution over current CCD spectroscopy, XRISM is now revealing the dynamics of hot atmospheres in galaxy clusters. I will review the first results from the performance verification phase and present our Cycle 1 observations of gas motions driven by AGN feedback in the Ophiuchus cluster. --- Thanks, Joe -------------- next part -------------- An HTML attachment was scrubbed...

Kind regards, Elisa ----------------------------------------- Speaker: Benjamin Muntz (Nottingham) Seminar date: November 18th , Tuesday, 1 pm UK time Venue: Seminar Room A 113 (Cripps North Building, CAPT) Title: On the Geometry of Gravitational Effective Field Theories Abstract: Field space geometries ? defined via the kinetic sector of an Effective Field Theory (EFT) ? have recently become central to questions in swampland, amplitudes, cosmology, and philosophy of physics. When the EFT couples to gravity, however, the status of this geometry becomes ambiguous: the field space metric transforms non-trivially under Weyl transformations, obscuring how geometry behaves covariantly across otherwise equivalent conformal frames. In this talk I present a new framework to resolve this ambiguity. I will explain how all possible conformal frames arise as different foliations of a particular higher-dimensional geometry. With the help of ADM, statements like frame- and unit transformations, as well as field excursions, receive a clean reinterpretation in differential-geometric language. This perspective also reveals precisely how gravity itself curves field space. Time permitting, I will illustrate two applications of our formalism: * First, I will prove the Species Scale Distance Conjecture and Sharpened Distance Conjecture, and argue that these are in fact universal statements of scalar-tensor theories rather than having to do with quantum gravity. * Second, I will show how to quickly calculate scattering amplitudes in Higgs inflation. What is otherwise a lengthy derivation now boils down to computing just a single field space Riemann tensor. -------------------------------------------------- Link to join: https://teams.microsoft.com/l/meetup-join/19%3ameeting_OGM3OTk5NzQtZWEwZS00ZmUyLTk3MGUtZjFhY2M5OTU2MjI1%40thread.v2/0?context=%7b%22Tid%22%3a%2267bda7ee-fd80-41ef-ac91-358418290a1e%22%2c%22Oid%22%3a%22f3250584-4b5f-48fa-a897-08e77f2246b7%22%7d List of upcoming Seminars: Nov 25th:?Fraser Cowie (Oxford) Dec 2nd: Violetta Sagun (Southampton) Dec 9th: James Alvey (Cambridge) -------------- next part -------------- An HTML attachment was scrubbed...

For many cases, by using calibration files such as the PSF, RMF and ARF, efficient simulations are possible at comparably high speed, even though they include nonlinear effects such as pileup. In this talk I will give an introduction to the software, while demonstrating example usage of SIXTE in High Energy Astrophysics. Monday 17th November at 3pm, A113 CAPT ? Theoretical Physics Student Seminar Thomas Martin Modern Kinetic Theory --- Tuesdays at 11am, CAPT Foyer ? Astro Coffee Tuesday 18th November at 1pm, A113 CAPT ? Particle Cosmology and Gravity Seminar Benjamin Muntz On the Geometry of Gravitational Effective Field Theories Field space geometries ? defined via the kinetic sector of an Effective Field Theory (EFT) ? have recently become central to questions in swampland, amplitudes, cosmology, and philosophy of physics. When the EFT couples to gravity, however, the status of this geometry becomes ambiguous: the field space metric transforms non-trivially under Weyl transformations, obscuring how geometry behaves covariantly across otherwise equivalent conformal frames. In this talk I present a new framework to resolve this ambiguity. I will explain how all possible conformal frames arise as different foliations of a particular higher-dimensional geometry. With the help of ADM, statements like frame- and unit transformations, as well as field excursions, receive a clean reinterpretation in differential-geometric language. This perspective also reveals precisely how gravity itself curves field space. Time permitting, I will illustrate two applications of our formalism: * First, I will prove the Species Scale Distance Conjecture and Sharpened Distance Conjecture, and argue that these are in fact universal statements of scalar-tensor theories rather than having to do with quantum gravity. * Second, I will show how to quickly calculate scattering amplitudes in Higgs inflation. What is otherwise a lengthy derivation now boils down to computing just a single field space Riemann tensor.

Please find his talk abstract below. ***************** Multi-Scale Pathways to Galaxy Quenching The big evolutionary change in the life of a galaxy is its transition from a star-forming to a passive state. In this talk, I will discuss several possible physical mechanisms that can induce this transition, each acting in a different regime of galaxy mass and/or large-scale environment. I will discuss how satellite galaxies may lose gas as they slam into the hot medium characterising massive haloes, how massive galaxies may be limited by their ability to accrete gas from the large-scale environment, and how intermediate-mass galaxies may fail to retain their gas after internal explosions. I will describe new progress on each of these mechanisms but highlight the puzzles that stand in the way of a complete understanding. Ultimately, I?ll discuss how new wide-field surveys will deliver answers to these puzzles. ***************** The seminar will be in the Physics Building C4 at 15:45, followed by the wine and cheese in the usual place. If you want to join us for lunch or want to arrange a meeting with Sean just let us know.

Padua-Arg?elles (Perimeter Institute and University of Waterloo) Title: Entropies for gravitational systems from simplicial Lorentzian path integrals Abstract: Recent advances have argued how gravitational entropies can be computed directly from Lorentzian path integrals, avoiding the problems of Euclidean methods associated with the conformal factor problem that makes a path integral over Euclidean geometries manifestly ill defined. In particular, the de Sitter horizon entropy can be recovered from a real-time path integral that computes the dimension of the Hilbert space associated with a spatial ball. Similarly, the swap entropy of an evaporating black hole (central to the replica paradigm resolution of the black hole information paradox) can be computed in this way. Quantum Regge Calculus, a lattice-like approach to quantum gravity, enables concrete realizations of these scenarios, providing insights beyond continuum methods. This perspective clarifies aspects of gravitational path integrals and may have implications for approaches such as causal dynamical triangulations and spin foams, where Regge-like formulations play a fundamental role. | Jorma Louko | School of Mathematical Sciences | University of Nottingham Tel: +44 115 95 14942 | Nottingham NG7 2RD jorma.louko at nottingham.ac.uk | United Kingdom www.nottingham.ac.uk/mathematics -------------- next part -------------- An HTML attachment was scrubbed...

CAPT Coding Club Wednesday 26th November at 3pm, B13 Physics ? School Colloquium Dr Anton Souslov (Cambridge) Active Solids Active solids consume energy to allow for actuation and shape change not possible in equilibrium. I will introduce non-reciprocal active solids as a novel class of active matter based on constituents that interact without action-reaction symmetry, leading to unusual elastic and mechanical properties. In the first part of this talk, I will explore the anomalous relation between microscopic structure and emergent elasticity in these materials, which we dub "more is less": as microscopic activity increases, macroscale active response can vanish. In the second part, I will talk about instabilities in these materials, leading to the formation and coarsening of dynamical patterns. Finally, I will discuss the surprising functionality of these systems, for example locomotion. These results unveil unusual facets of active matter, offering new principles for engineering materials far from equilibrium. --- Thursday 27th November at 1pm, A113 CAPT ?

Title and abstract below. Title: Environmental Imprints on Galaxies: Filaments, ICL, and AGN Activity Abstract: I will present an overview of my recent work on how galaxies evolve within different cosmic environments. I will begin with results on galaxies residing in large-scale filaments, examining how the cosmic web affects their growth and star-formation activity. I will then discuss using intracluster light (ICL) as a tracer of the underlying dark matter distribution in galaxy clusters. Finally, I will highlight findings on how the local environment influences AGN activity and the processes that regulate black hole fueling. Together, these studies illustrate the multi-scale environmental factors that shape galaxy evolution. Thanks, Joe -------------- next part -------------- An HTML attachment was scrubbed...

Please find below the title and the content of the seminar. ***************** Probing the Assembly of Low Star-formation Galaxies via Population-Orbit Superposition Method Understanding the formation of low star-formation galaxies is key to unraveling the processes that drive galaxy evolution. My talk will mainly contain three parts: In the context of the Fornax3D project, we analyzed 21 galaxies in the Fornax cluster observed with MUSE/VLT by applying a novel population-orbit superposition method. By fitting the luminosity distribution, stellar kinematics, age and metallicity maps simultaneously, we obtained the internal stellar orbit distribution and stellar population distributions. Based on the model, we decompose the dynamically cold disk (orbital circularity ?z > 0.8) for each galaxy, and obtain its luminosity fraction, age and metallicity radial profiles. For galaxies in the Fornax cluster, we find that the luminosity fraction of cold disk in recent infallers are consistent with field galaxies from CALIFA, while the cold disk fractions in ancient infallers with tinfall > 8 Gyr are a factor of ? 4 lower, with control of stellar mass. Moreover, the stellar age of cold disk is highly correlated with galaxy infall time into the cluster, and we find positive age gradients in cold disks, with stars in the inner disk being younger than those in the outer disk, contrary to the expectation of inside-out growth. We then directly compare our results with galaxies in Fornax-like clusters in TNG50 simulations, and find that they agree with each other remarkably well on cold disk fractions, stellar age, age gradients, and their dependence on galaxy?s infall time to the cluster. In the simulations, we find gas in the outer disk was partly removed and partly compacted into the inner regions when falling into the cluster, which leads to quick stop of star formation in the outer disk, but a long tail of star formation in the inner regions. The turnover of star formation radius from out to inner regions is highly correlated with the galaxy?s infall time. This process explains most of the above results. At the same time, tidal shocking partially heats the cold disk formed before infall, which further reduces the cold disk fraction in ancient infallers which bear the strongest tidal effects. Finally, we analyzed one low star-formation S0 galaxy in the GECKOS survey - a VLT/MUSE large program targeting 36 nearby edge-on galaxies at Milky Way mass. We find an old, metal-poor nuclear stellar disk, an extended main disk in this galaxy. It shows a strong negative age gradient in unclear disk and a strong positive age gradient in main disk. The presence of an old nuclear disk suggests the existence of an ancient bar structure. Furthermore, we find that both the cold disk fraction and the age gradient align with those observed in galaxies from the Fornax cluster, implying that environment may play only a limited role in shaping the evolution of low star-formation galaxies. ***************** The seminar will be in the Physics Building C4 at 15:45, followed by the wine and cheese in the usual place. If you want to join us for lunch or want to arrange a meeting with Yuchen just let us know. Best, Jesse , Luke & Tutku ? -------------- next part -------------- An HTML attachment was scrubbed...
