EDGE-INFERNO: The chemical signatures of assembly history in reionization fossils
Eric P. Andersson, Martin P. Rey, Alexander P. Ji +9
In galaxies, stellar populations represent a superposition of both in situ and accreted components, tracing internal chemical evolution as well as the histories of merged satellite…
Early onset of the hot circumgalactic medium around Milky Way galaxies
Víctor Rufo-Pastor, Oscar Agertz, Santi Roca-Fábrega +6
Hot coronae are key regulators in Milky Way (MW)-type galaxy formation and are thought to emerge once a galaxy's dark matter halo crosses a critical mass threshold, $M_{\mathrm{vir…
MEGATRON: Dwarf Galaxy Quenching in the Epoch of Reionization
David Attard, Ilian T. Iliev, Martin P. Rey +3
Low-mass galaxies during the Epoch of Reionization are expected to form stars in short bursts separated by periods of inactivity, but what regulates this cycle, and how sensitive i…
MEGATRON: The Physical Origins of Steep UV Slopes at High Redshift
Harley Katz, Nicholas Choustikov, Aayush Saxena +7
The ultraviolet (UV) spectral slope, , serves as a fundamental probe of stellar population properties and interstellar medium conditions in galaxies. At high redshift, a small s…
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…
VINTERGATAN-GM: long-lived satellite planes induced by a massive GSE-like merger
R. Rodríguez-Cardoso, S. Roca-Fàbrega, 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…
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…
