Astro Coffee Tuesdays at 11.30am, A113 CAPT ? Astronomy Journal Club --- Wednesday 14th January at 3.45pm, C4 Physics ? Astronomy Weekly Seminar Ilin Hazar (Herts) Dwarf galaxies in deep-wide surveys: a new frontier in the study of galaxy evolution Dwarf galaxies dominate the galaxy number density at all epochs and all environments, making them critical to our understanding of galaxy evolution. However, typical dwarfs are too faint to be visible outside the very local Universe in past surveys like the SDSS, which offer large footprints but are relatively shallow. In this study I use data from Ultra Deep layer (i<27.5 mag) of Hyper Suprime-Cam (which is around 10 magnitudes deeper than the SDSS spectroscopic sample) to present results on: (1) the morphological mix of the dwarf population in the nearby Universe, (2) the dwarf stellar mass function across different environments with a focus on the missing dwarf problem and (3) the galaxy red fraction and the validity of the ?downsizing? phenomenon in the dwarf regime. Our dwarf samples are formed of dwarfs (M? < 10^9.5 MSun) in the COSMOS and XMM-LSS fields reaching redshifts of z=0.4 and lower stellar mass limits of 10^7 MSun. We find that ~45 and ~45 per cent of dwarfs exhibit the traditional 'early-type' (elliptical/S0) and 'late-type' (spiral) morphologies, respectively. However, 10 per cent populate a 'featureless' class, that lacks both the central light concentration seen in early-types and any spiral structure - this class is missing in the massive-galaxy regime. Compared to their massive counterparts, dwarf early-types show a much lower incidence of interactions and are significantly less concentrated. This suggests that the formation histories of dwarf and massive early-types are different, with dwarf early-types being shaped less by interactions and more by secular processes. In addition, we find that it is challenging to cleanly separate early and late-type dwarfs using traditional morphological parameters such as ?CAS?, M20 and the Gini coefficient (unlike in the massive galaxy regime). We find no evidence of a generic missing dwarf problem when all environments are considered (and not just satellites of Milky Way like galaxies). Finally, ?downsizing? does not continue uninterrupted into the dwarf regime and the galaxy red fraction starts increasing again from M? = 10^8.5 MSun towards lower stellar masses. I will end with presenting future prospects/plans for dwarf galaxy evolution studies in the era of Euclid and LSST. --- Thursday 15th January at 1pm, A113 CAPT ?

The more the better, from all research groups (including those in SPMIC and CAPT!). You may or may not know about the tradition of postgrads meeting for a cup of tea (or coffee or juice!) in the postgraduate common room every morning (10:45-11:15) and afternoon (3:45-4:15). In the past (cue Dvorak's New World Symphony in the Hovis advert...) a large number of postgraduates used to get together for a drink at these times. It was a great way to meet up and chat with fellow postgrads from all over the School, from the various different research groups, and a natural place to organise social or sporting events. As well as adding to the sense of community, it also spawned some neat research ideas spanning different groups (and was a place to get the low down on the bits of kit you needed but never thought existed.) The tradition never recovered after covid unfortunately (although I know many of you continue to use the space for lunch). Chris Morley is still there most days though, valiantly continuing to serve tea and coffee, morning and afternoon. I know that many of you have expressed a desire for more opportunities to meet and talk with other postgraduates on a social level, both within and outside your research group. I have a proposition for you: in an attempt to get a critical mass of people together to restart the 'tea club' (for want of a better phrase), I would like to invite you to come along to the postgraduate common room (C10, main building) on Monday 26th January at 10:45. The more people who come the better. 40p for a cup of tea, bring your own mug! (If you don't have cash, Chris operates an informal tab.) Obviously, my hope is that many of you will continue to drop into the PG common room to 'go to tea' regularly after that. (I'll put out another call in a few weeks for the benefit of those not able to make it on Monday 26th.)

Astro Coffee Tuesdays at 11.30am, A113 CAPT ? Astronomy Journal Club --- Wednesday 21st January at 3.45pm, C4 Physics ? Astronomy Weekly Seminar Prof Rita Tojeiro (St Andrews) Breaking down the galaxy-halo connection In the current standard model of structure and galaxy formation, the evolution of galaxies and halos are intrinsically linked. Understanding the galaxy-halo connection is therefore needed for a holistic view of extragalactic astronomy, testing structure formation theories, or inferring cosmological parameters from galaxy surveys. As such, modelling it has been a major effort of the extragalactic and cosmology community for decades. Drawing on my group?s recent work in observations and in simulations, I will consider how to break down the galaxy-halo connection in different physical and time scales. I will focus on the relationship between halo assembly and star-formation histories, stochasticity, and the cosmic web, with the goal of developing new ways in which to test models of the galaxy-halo connection with current and forthcoming surveys. --- Thursday 22nd January at 1pm, A113 CAPT ? Astronomy Lunch Talk Harry Gully Euclid Q1: The evolution of the ICL fraction The intracluster light (ICL) fraction and its evolution with redshift can provide constraints on the dominant mechanisms of ICL production. I will present measurements of ICL fractions for a sample of galaxy clusters spanning 0.2 < z < 1.6. Our results show that significant ICL is already in place at z > 1, and there is no clear evidence for evolution in the ICL fraction across this redshift range. This suggests that a significant portion of ICL formation occurs early during cluster assembly, and that its buildup over time tracks the growth of the cluster itself. --- Fridays at 4pm, CAPT Foyer ?

Particle Cosmology and Gravity Seminar Thomas Spieksma (Oxford) The environment talks back: Black hole binaries beyond vacuum After a decade of gravitational-wave detections, the field is entering a new era. With next-generation detectors on the horizon, the key question is no longer how many sources we will observe, but how much physics we can extract from them. Addressing this challenge requires moving beyond some of the simplifying assumptions used in most studies so far, such as circular orbits, aligned spins, or black holes evolving in vacuum. Paradoxically, it is precisely these complexities that may encode the richest opportunities for gravitational waves to reveal new astrophysical phenomena and, potentially, new fundamental physics. In this talk, I will focus on one such scenario by discussing how astrophysical environments can influence black hole binaries. In particular, I will describe the signatures that superradiant boson clouds may imprint on gravitational-wave signals and outline the modelling tools being developed to accurately capture the dynamics of these systems. I will also highlight the key open problems and challenges that must be addressed to fully realise this potential.

School Colloquium Emma Chapman Should we just give up? Continuing the search for the first stars The Epoch of Reionization (EoR) follows the end of the Dark Ages of the Universe and signals the birth of the first stars. The aim of the current generation of radio telescopes is to make the first statistical detection of this epoch, covering 400 million - 1 billion years after the Big Bang. For the next generation Square Kilometre array, we will have an order of magnitude improved sensitivity and can pursue imaging over this time. However, foregrounds cover the cosmological data by several orders of magnitude, and their removal remains a significant challenge. It has been over a decade since we turned on the current generation telescope LOFAR, and still there is no detection? should we just give up? Refreshments served in C10 after the Colloquium --- Thursday 29th January at 1pm, A113 CAPT ? Astronomy Lunch Talk Jacob Campbell Co-ordinate transformations in substructure detection using gravitational lensing Strong gravitational lensing provides a natural probe for dark matter distributions around galaxies due to its sole dependence on the mass distribution of the lens galaxy. Over the past decade, machine learning has been coupled with this in an attempt to establish a pipeline for extracting substructure information from lensing images in anticipation of the next generation of wide surveys such as Euclid and LSST. As of yet, however, the required accuracy has yet to be obtained, highlighting a need for more advanced machine learning architectures and techniques. In this talk, I will present a data augmentation technique that boosts network performance without the need for higher resolution observations or more complex machine learning architectures.

Astronomy Journal Club Tuesday 3rd February at 1pm, A113 CAPT ? Particle Cosmology and Gravity Seminar Qi-Xin Xie Quantum fields in boson star spacetime Boson stars have been extensively studied in classical gravity, but their quantum properties remain comparatively unexplored. We compute the quantum scalar fields and stress tensor in boson star spacetimes within the framework of semiclassical gravity. Divergences are regularized using Pauli-Villars fields, and accurate numerical results are obtained through spectral methods. Employing coherent states enables a direct comparison between the classical part of the stress tensor and the quantum fluctuation. Our results indicate that strong spacetime curvature is the primary source of large quantum effects. The renormalized quantum energy density is mostly positive but the radial pressure is negative, suggesting that classical boson star solutions require modification once quantum effects are included. Moreover, in regimes of large curvature, the quantum fluctuations can constitute a significant fraction of the total stress tensor. The methods developed here can be generalized to other compact objects and used to study their response to quantum corrections.
