Astronomy Weekly Seminar Yuchen Ding (LJMU) 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. --- Thursday 4th December at 1pm, A113 CAPT ?

The details are provided below. Kind regards, Elisa ----------------------------------------- Speaker: Violetta Sagun (Southampton) Seminar date: December 2nd, Tuesday, 1 pm UK time Venue: Seminar Room A 113 (Cripps North Building, CAPT) Title: Dark matter imprints on the neutron star properties and merger dynamics Abstract: Binary neutron star mergers provide insights into strong-field gravity and the properties of ultra-dense nuclear matter. These events offer the potential to search for signatures of physics beyond the Standard Model, including dark matter. We present the first numerical-relativity simulations of binary neutron star mergers admixed with dark matter, based on constraint-solved initial data. Modeling dark matter as a non-interacting fermionic gas, we investigate the impact of varying dark matter fractions and particle masses on the merger dynamics, ejecta mass, post-merger remnant properties, and the emitted gravitational waves. Our simulations suggest that the dark matter morphology - a dense core or a diluted halo - may alter the merger outcome. Scenarios with a dark matter core tend to exhibit a higher probability of prompt collapse, while those with a dark matter halo develop a common envelope, embedding the whole binary. Furthermore, gravitational wave signals from mergers with dark matter halo configurations exhibit significant deviations from standard models when the tidal deformability is calculated in a two-fluid framework neglecting the dilute and extended nature of the halo. This highlights the need for refined models in calculating the tidal deformability when considering mergers with extended dark matter structures. These initial results provide a basis for further exploration of dark matter's role in binary neutron star mergers and their associated gravitational wave emission and can serve as a benchmark for future observations from advanced detectors and multi-messenger astrophysics. -------------------------------------------------- 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: Dec 9th: James Alvey (Cambridge) -------------- next part -------------- An HTML attachment was scrubbed...

Title and abstract below. Title: Star formation quenching in z ~ 0 groups and clusters Abstract: Isn?t this a solved problem? As it turns out, no. Even though we are now probing group/cluster environments out to z > 2, there is still much we do not know even in the local Universe, including how commonly star formation is actually shut down in group and cluster galaxies - the quenched fraction. In my talk, I will give an update on this topic from a combined observation and simulation perspective. On the observational side I will present a new analysis of the GAMA survey to quantify the quenched fraction over two orders of magnitude in stellar and halo mass, based on from full spectrum fitting (for star formation rates) and detailed matching to the FLAMINGO simulations (for halo masses). I will then compare these quenched fractions to predictions from the new COLIBRE simulations to test whether our theoretical expectations agree with reality.

The speaker, Javier Carballo, together with Paolo Arnaudo, will be visiting us from 9 December to 11 December from the University of Southampton. Please get in touch with them (cc'd) if you would like to arrange a meeting. When: 11am, Wednesday December 10th Where: C05 Physics Javier Carballo (U of Southampton) "A complete mode decomposition of black hole perturbations" It is well known that quasinormal modes (QNMs) do not form a complete basis for linear black hole perturbations. In particular, retarded Green's functions of black holes can only be decomposed as a convergent sum of QNMs at sufficiently late times. In this talk, I will show that Green's functions can be expanded as a convergent mode sum everywhere in spacetime. When QNMs fail at early times, a sum of Matusbara modes (MMs) associated to the horizon temperature converges instead. I will present the case of the Schwarzschild black hole, where the branch cut is resolved into a set of de Sitter modes by adding a small positive cosmological constant. Based on 2510.18956.

Kind regards, Elisa ----------------------------------------- Speaker: James Alvey (Cambridge) Seminar date: December 9th, Tuesday, 1 pm UK time Venue: Seminar Room A 113 (Cripps North Building, CAPT) Title: AI and the Era of Big Data Challenges in Gravitational Waves Abstract: The next generation of observatories, such as LISA and the Einstein Telescope, will usher in a big data era for gravitational wave astrophysics. These instruments will detect thousands of coincident signals, resulting in a complex data analysis challenge. Standard Bayesian inference techniques, such as MCMC and nested sampling, scale poorly with the high dimensionality of this problem, rendering a full analysis computationally challenging. In this seminar, I will discuss the ways in which I believe AI and machine learning can provide a viable path forward.

These instruments will detect thousands of coincident signals, resulting in a complex data analysis challenge. Standard Bayesian inference techniques, such as MCMC and nested sampling, scale poorly with the high dimensionality of this problem, rendering a full analysis computationally challenging. In this seminar, I will discuss the ways in which I believe AI and machine learning can provide a viable path forward.

In this talk, I will show that Green's functions can be expanded as a convergent mode sum everywhere in spacetime.

Astronomy Weekly Seminar Dr Kate Harbourne (Durham) Swooping in on the drivers of the spin-age relation using COLIBRE Observations from the SAMI integral field spectroscopic survey have demonstrated that older galaxies have lower spin and younger galaxies have higher spin, even when the effects of stellar mass and environment are controlled. Possible driver of this ?spin-age? relation include the presence of internal secular heating driven by bars and spiral arms, progenitor bias and the impact of mergers. In the next-generation EAGLE simulation, COLIBRE, we find a population of high-spin, flattened galaxies and evaluate the origin of the spin-age relation in this new cosmological, hydrodynamical simulation. This presentation will demonstrate the emergence of a realistic spin-age relation in COLIBRE, explore the role of bars, mergers and progenitor bias in driving this relation, and make comparison to the same observed relation in the SAMI survey. I'll also be demonstrating how consistent comparisons between observations and simulations are important, and advocate for the use of mock observations towards this aim. Using the open-source, mock-IFU software, SimSpin, I'll show how observational systematics are properly accounted for in this investigation. --- Thursday 11th December at 1pm, A113 CAPT ?

Multicomponent decomposition of the ICL and BCG will allow us to drastically improve our understanding of the transition region between the BCG and ICL, to constrain the relative contribution of the BCG and ICL with unprecedented precision, and to determine the utility of ICL as a luminous tracer of dark matter.

Our speaker will be Callum Bellhouse - title and abstract below. Title: Morpho-Kinematic Decomposition of Intracluster Light with MUSE Abstract: The Intracluster Light (ICL) is a diffuse component which contributes a substantial yet poorly constrained portion (5-25%) of a cluster's stellar population. ICL is tightly linked to the hierarchical evolution of galaxy clusters and is a possible luminous tracer of the dark matter halo's profile, tracing the same gravitational potential. One of the biggest challenges in ICL observations is decomposing the ICL from the Brightest Cluster Galaxy (BCG), which is impossible using photometry alone without making significant assumptions about the relative profiles. I will present a pilot project which incorporates MUSE integral-field spectroscopy and HST imaging to carry out morpho-kinematic decomposition of the ICL and BCG in AS1063, measuring spatially-resolved kinematics and spectral properties of the BCG and ICL out to >100kpc from the cluster centre, and comparing with the phase-space and mass distribution of cluster galaxies to test the utility of the ICL as a dark matter tracer. Multicomponent decomposition of the ICL and BCG will allow us to drastically improve our understanding of the transition region between the BCG and ICL, to constrain the relative contribution of the BCG and ICL with unprecedented precision, and to determine the utility of ICL as a luminous tracer of dark matter.

PID2023-150393NB-I00) by the Spanish Ministry of Science & Innovation (PI: F. Buitrago & B. Sahelices). The selected candidate's work will consist in the development of Machine Learning algorithms to detect Low Surface Brightness distant galaxy features, paying special attention to the truncations/galaxy edges in Euclid data (and its simulations) and other ultradeep data (HST, JWST). They will also have 30% of their time free to conduct any previous research projects. Due to the scientific objectives to be achieved, a strong profile on Machine Learning will be preferred --see conditions in the provided links, where also the necessary documentation is detailed: passport copy, CV, publication list, etc.-- and thus not only people with an Astrophysics background are encouraged to apply but also more technical profiles. The University of Valladolid actively seeks a diverse applicant pool and encourages candidates of all backgrounds to apply. Please mind that, according to the University regulations, if your PhD was not undertaken in Spain, you must also apply for the official recognition (https://www.uva.es/export/sites/uva/2.estudios/2.08.homologaciondetitulo/) and attached this certificate to the application. The successful candidate will undertake their work on F. Buitrago's group and will benefit from all his national/international collaborations (Euclid's Local Universe --where the PI leads the Diffuse Light Working Package-- and Galaxy Evolution working packages, Low Surface Brightness collaborations with IFCA, ICE, etc., ARRAKIHS and others like MOONS and 4HS). A strong interaction with the UVa Computer Science department and the UVa Mathematical Physics group are also expected. Both departments have a very nice working atmosphere and conduct regular seminars, giving also the opportunity to supervise BSc and MSc students. Valladolid is a large and lively city at an hour's distance from Madrid. It is located at the center of the Castille region, and thus with plenty of monumental places and astounding nature nearby. The salary will be 42.100? euros/year before taxes (12 pays per year) and the contract duration is expected to be approximately 23 months (February 1st 2026 to --at least-- 31st August 2027, although we will push ask for an extension until the end of 2027 and the exact dates are negotiable). In addition to the salary, the successful person appointed as postdoctoral research associate will also receive full Spanish Healthcare social benefits (e.g. medical insurance and parental leave) and an end-of-contract payment of approximately 2.300?. They will make use of the UVa machine-learning computer facilities (and several dedicated server with powerful graphic cards). Do not hesitate to put in contact (fbuitrago at uva.es) in case you have any questions (or problems with the documentation in Spanish). Please also provide two reference letters --sent directly by the reference researchers-- to the aforementioned email address. The deadline for sending the documentation via the UVa system is December 31st 2025, after which a selection of applicants will be made followed by interviews to those in the short list. Thank you very much for your attention, Fernando Buitrago ps.

Below is the description of the subject. The position will be for 2 years. In the ?CDM framework, modelling the rotational velocities of galaxies relies on dark matter. There are many candidates (WIMPs, axions, scalar fields, etc.), but no particles have been detected to date. Alternatives propose modifying Newton's laws at low accelerations (~10^(-10) m.s2) (i.e. MOND) to account for the observed rotation curves. However, these models often use ad hoc interpolation functions and acceleration scales to deviate from the Newtonian regime. A recent model - the quantum modified inertia (QMI) - introduces a new principle of dynamics with minimal acceleration of quantum origin developed within the framework of special relativity (https://arxiv.org/abs/2507.11524). Based on this principle, a simple code has been developped that successfully recover several spiral rotation curves, and even the rising curve of dwarf galaxies that, in the LCDM theory, are difficult to explain. The post-doc work will be to improve the code to apply it to various galaxy types. Furthermore, it has been recently shown that the radial acceleration relation (RAR, see http://arxiv.org/abs/1610.08981) proposed to support the MOND theories was excluded by the Cassini probe trajectory (https://arxiv.org/abs/2401.04796). One possibility for reconciling the RAR deduced from the SPARC galaxy data set (used by Lelli et al) with Cassini constraint is to refine the stellar-to-mass ratios. The postdoc will explore the sensitivity of the RAR to the stellar-to-mass ratio at different wavelengths, using different hypotheses of Galactic evolution (IMF, star formation history, dust content...) through population synthesis modelling with existing codes. At the present time the RAR is based mainly on one sample of galaxies (the SPARC sample). The postdoc will look for and explore other data sets that could confirm or rule it out, therefore constraining the modified gravitation or inertia model, or modified it such that it best explains all available galaxy types, from massive galaxies to dwarfs, as well as the Cassini constraint. The candidate should have his/her PHD for less than 10 years and provide a summary of his/her career paths, a List of 5 principal publications, and main skills and expertises. The financial support will be covered by the Region Bourgogne-Franche-Comt? after a dedicated application form due by early january. Interested candidates can contact Annie Robin (annie.robin at obs-besancon.fr) and Jonathan Gillot (jonathan.gillot at femto-st.fr). Applications are requested before 28th december.
