mitigating the overcooling problem with sink-based bursty star formation in a high-z dwarf galaxy
Cheonsu Kang, Taysun Kimm, Daniel Han +4
Star formation is a fundamental driver of galaxy evolution, yet many galaxy formation models still fail to regulate it realistically, allowing gas to collapse too efficiently and o…
Statistical Predictions of the Accreted Stellar Halos around Milky Way-Like Galaxies
J. Sebastian Monzon, Frank C. van den Bosch, Martin P. Rey
In the CDM paradigm, stellar halos form through the accretion and disruption of satellite galaxies. We introduce new semi-analytic modeling within the SatGen framework to track…
VINTERGATAN-GM: long-lived satellite planes induced by a massive GSE-like merger
R. RodrÃguez-Cardoso, S. Roca-FÃ brega, Oscar Agertz +7
Satellite galaxies in the Local Group tend to be distributed in thin, planar configurations, with many sharing coherent orbital motion. Galaxy formation simulations in CDM have…
MEGATRON: The environments of Population III stars at Cosmic Dawn and their connection to present day galaxies
Anatole Storck, Harley Katz, Julien Devriendt +7
We present results of Pop. III formation in the MEGATRON suite of simulations, which self-consistently follows radiation and non-equilibrium chemistry, and resolves gas at near-pc…
MEGATRON: Disentangling Physical Processes and Observational Bias in the Multi-Phase ISM of High-Redshift Galaxies
Nicholas Choustikov, Harley Katz, Alex J. Cameron +10
Now detected out to redshifts of , the rest-frame ultraviolet and optical spectra of galaxies encode numerous physical properties of the interstellar medium (ISM). Accu…
The Impact of Star Formation and Feedback Recipes on the Stellar Mass and Interstellar Medium of High-Redshift Galaxies
Harley Katz, Martin P. Rey, Corentin Cadiou +2
We introduce MEGATRON, a new galaxy formation model for cosmological radiation hydrodynamics simulations of high-redshift galaxies. The model accounts for the non-equilibrium chemi…
