Hidden Disruption in Milky Way-like Satellite Galaxy Populations
Gray Thoron, Nora Shipp, Alexander H. Riley +9
Determining whether a satellite galaxy is tidally disrupting from photometric observations alone remains a fundamental challenge in near-field cosmology. Cosmological simulations o…
Same galaxy, different CGM: how the metal loading of galactic winds regulates the baryon cycle in Milky Way-mass galaxies
Prachi Khatri, Freeke van de Voort, Rebekka Bieri +5
The circumgalactic medium (CGM) is both the reservoir of gas that fuels star formation and galaxy growth, and the repository for the mass, energy, and metals expelled through stell…
Astronomical Advantages of a Boost Mission to Facilitate HST Science into the 2030s: Imaging the Circumgalactic Medium of Galaxies
Matthew J. Hayes, Kate H. R. Rubin, Michelle A. Berg +20
We present the case for imaging ultraviolet line emission from highly ionized metals and HI Lya in the circumgalactic medium of galaxies, should the Hubble Space Telescope receive…
FEASTS and MHONGOOSE: HI Column Density Distribution at for
Jing Wang, Xuchen Lin, Ze-Zhong Liang +24
We present the first HI column density distribution function, , extending down to . This was derived from high-s…
Stirring Things Up: Bar-induced substructures in the stellar halo of a cosmological Milky Way analogue
Thomas Tomlinson, Francesca Fragkoudi, Andreia Carrillo +8
The stellar halo of the Milky Way contains the remnants of past accretion events, which could be detectable as substructures in the classical integrals of motion space, such as ene…
Age and metallicity of low-mass galaxies: from their centres to their stellar halos
Elisa A. Tau, Antonela Monachesi, Facundo A. Gómez +5
We aim to analyse the metallicity and the ages of the stellar halos of low-mass galaxies to better understand their formation history. We use 17 simulated low-mass galaxies from th…
The role of magnetic fields in ram pressure stripping of satellite galaxies in the circumgalactic medium around massive galaxies
Thomas A. Rintoul, Freeke van de Voort, Andrew T. Hannington +4
The presence of magnetic fields in galaxies and their haloes could have important consequences for satellite galaxies moving through the magnetised circumgalactic medium (CGM) of t…
Stellar-gas kinematic misalignments in EAGLE: lifetimes and longevity of misaligned galaxies
Maximilian K. Baker, Timothy A. Davis, Freeke van de Voort +1
The dominant processes by which galaxies replenish their cold gas reservoirs remain disputed, especially in massive galaxies. Stellar-gas kinematic misalignments offer an opportuni…
Anisotropic thermal conduction on a moving mesh for cosmological simulations
Rosie Y. Talbot, Rüdiger Pakmor, Christoph Pfrommer +4
In weakly collisional, strongly magnetised plasmas such as the intracluster medium (ICM), hot accretion flows and the solar corona, the transport of heat and momentum occurs primar…
Where has all the -process gone? Timescales for GRB-Kilonovae to Enrich their Host Galaxies
Anya E. Nugent, Alexander P. Ji, Wen-fai Fong +2
Neutron star (NS) mergers are currently the only observed source of -process production in the Universe. Yet, it is unclear how much -process mass from these mergers is incor…
Hydrodynamical simulations of the galaxy population: enduring successes and outstanding challenges
Robert A. Crain, Freeke van de Voort
We review the progress in modelling the galaxy population in hydrodynamical simulations of the Lambda-CDM cosmogony. State-of-the-art simulations now broadly reproduce the observed…
Magnetic field amplification in cosmological zoom simulations from dwarf galaxies to galaxy groups
Ruediger Pakmor, Rebekka Bieri, Freeke van de Voort +6
Magnetic fields are ubiquitous in the Universe. Recently, cosmological simulations of galaxies have successfully begun to incorporate magnetic fields and their evolution in galaxie…
The Structure and Dynamics of Massive High- Cosmic-Web Filaments: Three Radial Zones in Filament Cross-Sections
Yue Samuel Lu, Nir Mandelker, S. Peng Oh +5
We analyse the internal structure and dynamics of cosmic-web filaments that connect massive high- haloes. Our analysis is based on a high-resolution AREPO cosmological simulatio…
ALMACAL X: Constraints on molecular gas in the low-redshift circumgalactic medium
Anne Klitsch, Timothy A. Davis, Aleksandra Hamanowicz +3
Despite its crucial role in galaxy evolution, the complex circumgalactic medium (CGM) remains underexplored. Although it is known to be multi-phase, the importance of the molecular…
Exploring the diversity and similarity of radially anisotropic Milky Way-like stellar haloes: implications for disrupted dwarf galaxy searches
Matthew D. A. Orkney, Chervin F. P. Laporte, Robert J. J. Grand +7
We investigate the properties of mergers comparable to the Gaia-Sausage-Enceladus (GSE) using cosmological hydrodynamical simulations of Milky Way-like galaxies. The merger progeni…
Bringing Stellar Evolution & Feedback Together: Summary of proposals from the Lorentz Center Workshop, 2022
Sam Geen, Poojan Agrawal, Paul A. Crowther +34
Stars strongly impact their environment, and shape structures on all scales throughout the universe, in a process known as ``feedback''. Due to the complexity of both stellar evolu…
An ever-present snail shell triggered by a dark matter wake
Robert J. J. Grand, Rüdiger Pakmor, Francesca Fragkoudi +5
We utilize a novel numerical technique to model star formation in cosmological simulations of galaxy formation - called Superstars - to simulate a Milky Way-like galaxy with $\gtrs…
Resolved Molecular Gas Observations of MaNGA Post-starbursts Reveal a Tumultuous Past
Justin Atsushi Otter, Kate Rowlands, Katherine Alatalo +24
Post-starburst galaxies (PSBs) have recently and rapidly quenched their star-formation, thus they are an important way to understand how galaxies transition from star-forming late-…
