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