EDGE-INFERNO: How chemical enrichment assumptions impact the individual stars of a simulated ultra-faint dwarf galaxy
Eric P. Andersson, Martin P. Rey, Robert M. Yates +6
The chemical abundances of stars in galaxies are a fossil record of the star formation and stellar evolution processes that regulate galaxy formation, including the stellar initial…
MEGATRON: the impact of non-equilibrium effects and local radiation fields on the circumgalactic medium at cosmic noon
Corentin Cadiou, Harley Katz, Martin P. Rey +22
We present three cosmological radiation-hydrodynamic zoom simulations of the progenitor of a Milky Way-mass galaxy from the MEGATRON suite. The simulations combine on-the-fly radia…
The radial acceleration relation at the EDGE of galaxy formation: testing its universality in low-mass dwarf galaxies
Mariana P. Júlio, Justin I. Read, Marcel S. Pawlowski +6
A tight correlation between the baryonic and observed acceleration of galaxies has been reported over a wide range of mass () - the Radi…
MEGATRON: Reproducing the Diversity of High-Redshift Galaxy Spectra with Cosmological Radiation Hydrodynamics Simulations
Harley Katz, Martin P. Rey, Corentin Cadiou +21
We present the MEGATRON suite of cosmological radiation hydrodynamics simulations following the formation of Milky Way-mass galaxies from the earliest cosmic epochs when Population…
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…
MEGATRON: how the first stars can create an iron metallicity plateau in the smallest dwarf galaxies
Martin P. Rey, Harley Katz, Corentin Cadiou +23
We study the stellar mass-iron metallicity relation of dwarf galaxies in the new high-resolution MEGATRON cosmological radiation-hydrodynamics simulations. These simulations model…
The emergence of globular clusters and globular-cluster-like dwarfs
Ethan D. Taylor, Justin I. Read, Matthew D. A. Orkney +7
Globular clusters (GCs) are among the oldest and densest stellar systems in the Universe, yet how they form remains a mystery. Here we present a suite of cosmological simulations i…
Pavo: Stellar feedback in action in a low-mass dwarf galaxy
Michael G. Jones, Martin P. Rey, David J. Sand +13
MeerKAT observations of the recently discovered, extremely low mass galaxy, Pavo, have revealed a neutral gas (HI) reservoir that was undetected in archival HI single dish data. We…
The PARADIGM project II: The lifetimes and quenching of satellites in Milky Way-mass haloes
Gandhali D. Joshi, Andrew Pontzen, Oscar Agertz +2
The abundance and star-formation histories of satellites of Milky Way (MW)-like galaxies are linked to their hosts' assembly histories. To explore this connection, we use the PARAD…
EDGE: The emergence of dwarf galaxy scaling relations from cosmological radiation-hydrodynamics simulations
Martin P. Rey, Ethan Taylor, Emily I. Gray +14
We present a new suite of EDGE (`Engineering Dwarfs at Galaxy formation's Edge') cosmological zoom simulations. The suite includes 15 radiation-hydrodynamical dwarf galaxies coveri…
Theoretical Predictions for the Inner Dark Matter Distribution in the Milky Way Informed by Simulations
Abdelaziz Hussein, Lina Necib, Manoj Kaplinghat +5
We build a theoretical range for the Milky Way's (MW) inner dark matter (DM) distribution informed by the FIRE-2, Auriga, VINTERGATAN-GM, and TNG50 simulation suites assuming the c…
