CAMELS Environments: The Impact of Local Neighbours on Galaxy Evolution across the SIMBA, IllustrisTNG, ASTRID, and Swift-EAGLE Simulations

Xavier Sims, Daniel Anglés-Alcázar, Boon-Kiat Oh +6

Internal feedback from massive stars and active galactic nuclei (AGN) play a key role in galaxy evolution, but external environmental effects can also strongly influence galaxies.…

High-redshift Millennium and Astrid galaxies in effective field theory at the field level

James M. Sullivan, Carolina Cuesta-Lazaro, Mikhail M. Ivanov +6

Effective Field Theory (EFT) modeling is expected to be a useful tool in the era of future higher-redshift galaxy surveys such as DESI-II and Spec-S5 due to its robust description…

X-raying CAMELS: Constraining Baryonic Feedback in the Circum-Galactic Medium with the CAMELS simulations and eRASS X-ray Observations

Erwin T. Lau, Daisuke Nagai, Ákos Bogdán +7

The circumgalactic medium (CGM) around massive galaxies plays a crucial role in regulating star formation and feedback. Using the CAMELS simulation suite, we develop emulators for…

Discrepancies Between JWST Observations and Simulations of Quenched Massive Galaxies at : A Comparative Study With IllustrisTNG and ASTRID

Emma Jane Weller, Fabio Pacucci, Yueying Ni +2

Recent JWST observations have uncovered an unexpectedly large population of massive quiescent galaxies at . Using the cosmological simulations IllustrisTNG and ASTRID, we iden…

Field-level simulation-based inference with galaxy catalogs: the impact of systematic effects

Natalí S. M. de Santi, Francisco Villaescusa-Navarro, L. Raul Abramo +11

It has been recently shown that a powerful way to constrain cosmological parameters from galaxy redshift surveys is to train graph neural networks to perform field-level likelihood…

You Shall Not Pass! The propagation of low/moderate powered jets through a turbulent interstellar medium

Olga Borodina, Yueying Ni, Jake S. Bennett +6

Feedback from black hole-powered jets has been invoked in many cosmological simulations to regulate star formation and quench galaxies. Despite this, observational evidence of how…
