CALIMA: On-the-fly dust and PAH evolution for radiation-hydrodynamics galaxy formation simulations

Francisco Rodríguez Montero, Yohan Dubois, Harley Katz +2

Dust grains and polycyclic aromatic hydrocarbons (PAHs) actively contribute to the thermodynamics, chemistry, and radiative state of the interstellar medium (ISM), yet most ISM mod…

Downsizing does not extend to dwarf galaxies: identifying the stellar mass regimes shaped by supernova and AGN feedback

Ilin Lazar, Sugata Kaviraj, Garreth Martin +10

We explore how the fraction of red (quenched) galaxies varies in the dwarf galaxy regime (10^7 MSun < Mstar < 10^9.5 MSun), using a mass-complete sample of ~5900 dwarfs at z<0.15,…

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: 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…
