The Velocity Field Olympics: Assessing velocity field reconstructions with direct distance tracers

Richard Stiskalek, Harry Desmond, Julien Devriendt +5

The peculiar velocity field of the local Universe provides direct insights into its matter distribution and the underlying theory of gravity, and is essential in cosmological analy…

The dwarf stellar mass function in different environments and the lack of a generic missing dwarfs problem in ΛCDM

Ilin Lazar, Sugata Kaviraj, Garreth Martin +9

We combine deep photometric data in the COSMOS and XMM-LSS fields with high-resolution cosmological hydrodynamical simulations to explore two key questions: (1) how does the galaxy…

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…

MEGATRON: how the first stars 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…

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…

Cosmological simulations of the same spiral galaxy: satellite properties, the role of baryonic physics and star formation history in shaping dark matter cores/cusps

A. Nuñez-Castiñeyra, E. Nezri, P. Mollitor +3

We investigate the role of baryonic physics in shaping the population, structure, and internal dynamics of galactic subhalos using the Mochima suite of cosmological zoom-in simulat…
