Astronomy Lunch Talk George Becker (UC Riverside) Exploring the End of Reionization Studying the epoch of reionization carries a high potential for discovering new things about the IGM and galaxies in the early Universe. How those discoveries are made, however, depends partly on when reionization occurred. Over the past few years, multiple lines of evidence have strongly indicated that reionization ended later than previously thought, between redshifts five and six. This opens a number of observational opportunities, as well as challenges. I will describe the evidence for late-ending reionization, discuss some of the new ways in this era is being explored observationally, and touch on some of the potential implications for the IGM, high-redshift galaxies, and cosmology.

Astronomy Weekly Seminar Dr. Francesca Frankoudi (Durham) The formation, evolution, and dark matter content of barred galaxies in LCDM The advent of high resolution hydrodynamical cosmological simulations allows us to now study the internal dynamics of barred spiral galaxies -- such as our own Milky Way -- within the full ?CDM cosmological context. I will present what we have learnt about the formation and evolution of barred galaxies by comparing cosmological simulations to observations of both the Milky Way and nearby spiral galaxies. In particular, I will address the "When?" and the "How?" of bar formation in ?CDM, and discuss what this implies about our own Galaxy's formation history, as well as why some galaxies form bars and others don't. I will discuss how barred galaxies evolve throughout cosmic history, as well as the connection between bars and their host dark matter halos, which can help shed light on both the amount and the nature of dark matter. --- Thursday 5th June at 1pm, A113 CAPT ? Astronomy Lunch Talk Guillaume Hewitt No hidden monsters: Probing recently-quenched galaxies for obscured AGN with JWST This talk presents a mid-infrared study of recently-quenched galaxies with JWST, with the aim of searching for obscured AGN activity. We focus on the transition class of post-starburst galaxies (PSBs) which provide insight into the intermediate stage of galaxy evolution between star-forming and quiescent, a necessity for understanding what drives quenching and galaxy bimodality. For massive galaxies (M* > 10^10), quenching models frequently invoke AGN feedback, and PSBs often exhibit strong outflows, consistent with this scenario. However, recent studies of massive PSBs have found no evidence of excess AGN activity from their X-ray and optical properties. This lack of activity indicates either AGN are not the main quenching mechanism, are short-lived and do not linger into the PSB phase, or are heavily obscured. If dust obscured, the presence of AGN activity could still be detected through the infrared (IR) emission of this hot dust. To test this, we use a sample of ?150 photometrically-selected PSBs within the PRIMER-UDS field at 0.5 < z < 3.0, and utilise the 7.7 ?m and 18 ?m JWST/MIRI photometry (as well as an additional eight NIRCam and three HST wavebands) to probe the IR dust emission of these galaxies. We find interesting differences between low and high-mass PSBs, and interestingly no excess dust emission within the high-mass galaxies. This indicates there are no hidden AGN, or indeed residual star-formation within these galaxies. I will discuss the implications of these results on the current understanding of what quenches massive galaxies at these redshifts. Thursday 5th June at 3pm, A113 CAPT ?

Yet despite this wealth of detections, it is still unclear how black holes become bound into tight binaries that merge within the age of the Universe. Binaries that form and merge in isolation may have different parameters than those that form under via dynamical interactions. The masses and spins of binaries have typically been touted as keys to deciphering formation channels; however, these parameters have significant drawbacks as formation-channel indicators. The most robust indication of dynamical evolution is orbital eccentricity: isolated binaries will have essentially circular orbits at detection, while a fraction of dynamically-formed binaries will have measurable eccentricity. Gravitational waves from eccentric binaries are challenging to detect and analyse, yet in the last few years, a handful gravitational-wave events have been shown to contain tantalising hints of orbital eccentricity. Additionally, future gravitational-wave detectors will be sensitive to smaller binary eccentricities and earlier binary evolutionary epochs, enabling us to dive deeper into their formation stories. In this talk, I will demonstrate how eccentricity may be detected and leveraged to reveal details of a binary?s history. I will show how signals from eccentric binaries enable us to uncover external influences to their evolution, including perturbing tertiaries and circumbinary disks, with current and future detectors. I will review what we can learn about our population of binary black holes when we combine observations of their masses, spins, and eccentricity. I will also demonstrate how studying these parameters simultaneously reveals the formation scenarios of compact binaries. -------------------------------------------------- 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 [cid:b2ba8036-03a5-4616-9f6e-2e1900352195] Join conversation teams.microsoft.com List of upcoming Seminars: 17th June: Rachel Gray (Glasgow) ---------------------------------------------------------------------- With Regards, -Elisa & Swagat -------------- next part -------------- An HTML attachment was scrubbed...

Title and abstract are below. Title: Measuring the Shape of ICL and Dark Matter Halos in Hydrangea and Horizon-AGN Simulations Abstract: Intracluster light (ICL) has been proposed as a luminous tracer of dark matter (DM) in galaxy clusters, as these stars are not bound to any particular galaxy but are instead governed by the cluster?s gravitational potential. It has been found that the isophotal contours closely follow the mass distribution of clusters out to ~200kpc observationally and in simulations (Montes and Trujillo 2019, Alonso Asensio et al. 2020). In this talk, I will present a shape analysis of ICL and DM from the Hydrangea and Horizon-AGN simulations. The elliptical shapes and orientations of these components are calculated using the moment of inertia tensor, extending to radii of ~1Mpc, both in 2D projections and 3D. I will also explore how cluster properties, specifically halo mass and formation redshift, affect the shapes of ICL and DM.

Additionally, future gravitational-wave detectors will be sensitive to smaller binary eccentricities and earlier binary evolutionary epochs, enabling us to dive deeper into their formation stories. In this talk, I will demonstrate how eccentricity may be detected and leveraged to reveal details of a binary?s history. I will show how signals from eccentric binaries enable us to uncover external influences to their evolution, including perturbing tertiaries and circumbinary disks, with current and future detectors. I will review what we can learn about our population of binary black holes when we combine observations of their masses, spins, and eccentricity. I will also demonstrate how studying these parameters simultaneously reveals the formation scenarios of compact binaries.

Astronomy Weekly Seminar Seoyoung Lyla Jung (Oxford) The alignment of galaxies and AGN jets in the cosmic web environment Active galactic nuclei (AGN) play a crucial role in the evolution of massive galaxies, and their fueling and feedback efficiency depend on the environment. In this talk, I will present a study of the orientations of AGN jets and their optical counterpart in relation to the cosmic web environment. Using LOFAR Two-metre Sky Survey (LoTSS), DESI Legacy Imaging Surveys, and the SDSS cosmic filament catalogue, we find that galaxy optical major axes tend to align with cosmic filaments, suggesting the growth of galaxies through mergers along filaments. On the other hand, AGN jets, typically perpendicular to the host galaxy?s major axis, show more randomized orientations in cosmic filament environments. This supports a scenario where black holes in filaments experience chaotic accretion as a result of numerous galaxy mergers. I will discuss the implications of these results in terms of the large-scale alignment of radio jets, intrinsic alignment of galaxies, and anisotropic quenching of satellite galaxies. Our results highlight the role of cosmic filaments in shaping AGN feedback and galaxy evolution. --- Thursday 12th June at 1pm, A113 CAPT ? Astronomy Lunch Talk Adela Fernandez Measuring the Shape of ICL and Dark Matter Halos in Hydrangea and Horizon-AGN Simulations Intracluster light (ICL) has been proposed as a luminous tracer of dark matter (DM) in galaxy clusters, as these stars are not bound to any particular galaxy but are instead governed by the cluster?s gravitational potential. It has been found that the isophotal contours closely follow the mass distribution of clusters out to ~200kpc observationally and in simulations (Montes and Trujillo 2019, Alonso Asensio et al. 2020). In this talk, I will present a shape analysis of ICL and DM from the Hydrangea and Horizon-AGN simulations. The elliptical shapes and orientations of these components are calculated using the moment of inertia tensor, extending to radii of ~1Mpc, both in 2D projections and 3D. I will also explore how cluster properties, specifically halo mass and formation redshift, affect the shapes of ICL and DM. Thursday 12th June at 3pm, A113 CAPT ?

Title and abstract are below. Title: Measuring the Shape of ICL and Dark Matter Halos in Hydrangea and Horizon-AGN Simulations Abstract: Intracluster light (ICL) has been proposed as a luminous tracer of dark matter (DM) in galaxy clusters, as these stars are not bound to any particular galaxy but are instead governed by the cluster?s gravitational potential. It has been found that the isophotal contours closely follow the mass distribution of clusters out to ~200kpc observationally and in simulations (Montes and Trujillo 2019, Alonso Asensio et al. 2020). In this talk, I will present a shape analysis of ICL and DM from the Hydrangea and Horizon-AGN simulations. The elliptical shapes and orientations of these components are calculated using the moment of inertia tensor, extending to radii of ~1Mpc, both in 2D projections and 3D. I will also explore how cluster properties, specifically halo mass and formation redshift, affect the shapes of ICL and DM.

The scheduled start date is on 30TH JUNE and is likely to be done in 5 days. The work will mean that each electrical circuit within the building will need to be turned off, if possible, in turn at the fuse board / consumer unit for approximately 10-15 minutes each. Please could you distribute this information to all of your respective offices/lab users, so that they can make you aware of any problems this may cause or conditions that need to be met to allow this to happen. Dalkia will discuss any concerns or limitations with staff on the day also and accommodate your requirements. Dalkia and I will be happy to address any concerns before Dalkia?s arrival. I have attached the FAQ for these works for you to pass on to those it may concern, I urge everyone to read it before they ask further questions. Please could you inform everyone in your team and copy those in that would benefit from the information. Following on from the inspection further remedial works may be required to correct any issues that are identified.

The details are provided below - ----------------------------------------- Speaker: Rachel Gray (Glasgow) Seminar date: June 17th, Tuesday, 1 pm UK time Venue: Seminar Room A 113 (Cripps North Building, CAPT) Title: Using gravitational waves to solve the Hubble tension Abstract: Gravitational wave signals from compact binary mergers are of huge interest to the cosmology community due to their ability to act as standard sirens, providing measurements of luminosity distance which are independent of the cosmic distance ladder. This opens up new ways of measuring cosmological parameters, with particular focus on the Hubble constant, with the hopes of arbitrating the current Hubble tension. However, in order for this measurement to be made, additional redshift information is required. In the scenario where the merger is observed without a confirmed electromagnetic counterpart - true for all but one of the detections from the LIGO-Virgo-KAGRA collaboration to date - galaxy surveys, and the population of gravitational waves themselves, can be used to provide this missing information. I will introduce these latest methods and look at what the gravitational wave detections from the LIGO-Virgo-KAGRA collaboration can tell us so far, and how they might pave the way for solving the Hubble tension. -------------------------------------------------- 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 ?

Astronomy Weekly Seminar Elisabeth Sola (Cambridge) Unveiling galaxy assembly with Low Surface Brightness tidal features Hierarchical models of galaxy formation predict that galaxies grow through successive mergers, leaving behind tidal features?faint stellar structures that preserve a record of recent mass assembly. The properties of these features depend on the nature of the mergers that produced them, making them key tracers of galaxy evolution. However, their intrinsically low surface brightness (LSB) poses a major observational challenge, requiring tailored observing strategies and data processing techniques. In this talk, I will present a quantitative study of tidal features around hundreds of nearby galaxies, based on deep imaging from both ground-based (CFHT) and space-based (Euclid) telescopes. Using a dedicated annotation tool, we systematically characterised these features in terms of their photometric and geometric properties. I will explore the connections between the host galaxies and their tidal features, and discuss the insights these structures offer into the late-stage assembly of galaxies.

Science Public Lecture Jesse Golden-Marx Intracluster light: using light to illuminate the dark universe Join us this June as we explore the hidden architecture of the universe and the mysterious role of dark matter with Jesse Golden-Marx, Research Fellow in the Faculty of Science. Roughly 85% of all matter in the universe is made up of unseen and mysterious dark matter. Despite not being able to directly observe dark matter, galaxy clusters serve as a cosmic laboratory for astronomers to actively explore the nature of the dark universe. In this talk, Jesse will discuss how astronomers use the most massive galaxies in the universe (100x bigger than the Milky Way) along with the faint ?orphaned stars? that surround these massive galaxies to illuminate the properties of the unseen dark matter structures in the universe and inform the evolutionary roadmap that leads to the formation of these massive galaxies. Whether you are interested in the mysteries of the cosmos or the cutting-edge techniques astronomers use to explore them, this lecture is for you. This lecture is part of our monthly Science Public Lecture series, and everyone is welcome to join!

In particular the cosmological bootstrap program provides a new perspective toward the investigation of cosmological correlators at the end of inflation. In this talk, I will first briefly review the progresses on bootstrapping phenomenologically relevant correlators, which include the primordial bispectra from single field, multi-field and cosmological colliders. After that, I will introduce new twists on both the theoretical development and also the observational tests. On the theory side, we extend the bootstrap analysis to reexamine more realistic inflation models in UV-complete setups. Interestingly, for a particular example of string inflation, we identify an unnoticed UV-sensitive signature in cosmological correlators. For observational test, guided by the bootstrap computation, we initiate a comprehensive search for the most significant signal of cosmological collider physics in the latest CMB data. -------------------------------------------------- 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 Upcoming Seminars: Suratna Das (Ashoka U Delhi) : 25th July Friday 2 pm (There are no regular seminars between July 1st and mid-September).

Astronomy Lunch Talk Diego Pallero (Universidad T?cnica Federico Santa Mar?a, Chile) The formation pathways of S0-galaxies: Upcoming science with SPLUS and CHANCES-4MOST One of the fundamental problems in modern astrophysics is understanding the environment's role in the galaxy's evolution. Many works, both theoretical and observational, have focused on this topic. Nevertheless, it is not clear yet which are the main physical mechanisms behind the quenching of star formation. We used state-of-the-art C-EAGLE hydrodynamical simulations to characterize the moment when galaxies quench their star formation and suffer morphological transformations. We find that > 70% of galaxies suffer strong drops in their SFR before they are accreted onto the clusters, regardless of the cluster mass. However, most galaxies get completely quenched once they fall into galaxy clusters, several Gyr after this processing event. The culprit behind this quenching is primarily ram-pressure stripping, produced at the outskirts of the first cluster in which galaxies reside. Additionally, when looking specifically at the population of S0 galaxies, we found that lenticular galaxies can be split into two distinctive populations: first, a dominant population of satellite galaxies inhabiting massive haloes with no mergers at z<2, and second, a population of central lenticular galaxies inhabiting less massive haloes with a mixed merging history. This work suggests that S0s, and quenched galaxies in general, are formed primarily via ram-pressure stripping. These results will be tested with current and upcoming multiwavelength observations from surveys such as S-PLUS, CHANCES/4MOST, LOFAR and Euclid, and give us key hints on what to look for when trying to understand the origin of lenticular galaxies.

We used state-of-the-art C-EAGLE hydrodynamical simulations to characterize the moment when galaxies quench their star formation and suffer morphological transformations. We find that > 70% of galaxies suffer strong drops in their SFR before they are accreted onto the clusters, regardless of the cluster mass. However, most galaxies get completely quenched once they fall into galaxy clusters, several Gyr after this processing event. The culprit behind this quenching is primarily ram-pressure stripping, produced at the outskirts of the first cluster in which galaxies reside. Additionally, when looking specifically at the population of S0 galaxies, we found that lenticular galaxies can be split into two distinctive populations: first, a dominant population of satellite galaxies inhabiting massive haloes with no mergers at z<2, and second, a population of central lenticular galaxies inhabiting less massive haloes with a mixed merging history. This work suggests that S0s, and quenched galaxies in general, are formed primarily via ram-pressure stripping. These results will be tested with current and upcoming multiwavelength observations from surveys such as S-PLUS, CHANCES/4MOST, LOFAR and Euclid, and give us key hints on what to look for when trying to understand the origin of lenticular galaxies.
