Atomic hydrogen in galaxies in the COLIBRE simulations
Kyle A. Oman, Ruby J. Wright, Andrea Gebek +12
We present an overview of the properties of atomic hydrogen (HI) in galaxies at redshift in the COLIBRE cosmological galaxy formation simulations. COLIBRE directly simulates…
The origin of the stellar mass-size relation of satellite galaxies in the COLIBRE simulations
Bruno M. Celiz, Julio F. Navarro, Joop Schaye +9
We study the stellar mass-size relation of satellite galaxies in the COLIBRE suite of cosmological hydrodynamical simulations. Satellites deviate from the relation that holds for c…
The descendants of JWST galaxies in the COLIBRE simulations
Xu Zhao, Carlos S. Frenk, Andrew Pontzen +9
Recent observations with JWST have revealed a population of UV-bright galaxies at . This discovery naturally raises the question: what do such early galaxies evolve in…
The effect of galaxy interactions on star formation rates in the COLIBRE simulations
Quinten W. E. van Zegveld, Evgenii Chaikin, Joop Schaye +8
Observations and theory indicate that galaxy interactions enhance star formation rates (SFRs). However, the degree of enhancement and its dependence on the properties of the intera…
The influence of feedback on the baryonic content of haloes in the COLIBRE simulations
Jonathan J. Davies, Joop Schaye, Filip Huško +7
We present predictions for the relation between the halo gas mass fraction and halo mass, , from the COLIBRE cosmological simulations of galaxy formation…
The evolution of galaxy dust scaling relations in the COLIBRE simulations
Aswin P. Vijayan, James W. Trayford, Joop Schaye +11
We present dust scaling relations across cosmic time () for galaxies in the COLIBRE cosmological simulations. COLIBRE self-consistently tracks dust production, grow…
Cosmological simulations of the high-redshift galaxy population adopting a variable stellar initial mass function
Anna Durrant, Robert A. Crain, Cedric G. Lacey +15
JWST surveys reveal a greater space density of high-redshift UV-bright galaxies than predicted by conventional galaxy formation models. We present results from a cMpc cosmo…
The COLIBRE-SKIRT pipeline: Calibration-free dust radiative transfer postprocessing for cosmological simulations
Andrea Gebek, Maarten Baes, Nick Andreadis +16
Context. Three-dimensional dust radiative transfer provides a powerful framework to connect cosmological galaxy simulations to multiwavelength observations. Until recently, in larg…
A subgrid model for chemical enrichment in cosmological simulations
Camila A. Correa, Joop Schaye, Matthieu Schaller +6
We present the modules for stellar nucleosynthesis, stellar mass loss, and turbulent diffusion of the new COLIBRE subgrid model for cosmological hydrodynamical simulations of galax…
The evolution of the sizes and angular momentum content of galaxies in the COLIBRE simulations
Aaron D. Ludlow, Katy L. Proctor, Joop Schaye +12
We analyse the sizes and specific angular momentum content of galaxies in the Colibre cosmological hydrodynamical simulations spanning two orders of magnitude in mass resolution. W…
Unifying cluster and galaxy cosmology analyses using the galaxy-halo connection
Shulei Cao, Hao-Yi Wu, Andrés N. Salcedo +3
Galaxies and galaxy clusters trace the same cosmic density field, but their statistics have been modeled separately in cosmological analyses. We present a unified, simulation-based…
Cosmological back-reaction of baryons on dark matter in the CAMELS simulations
Matthew Gebhardt, Daniel Anglés-Alcázar, Shy Genel +13
Baryonic processes such as radiative cooling and feedback from massive stars and active galactic nuclei (AGN) directly redistribute baryons in the Universe but also indirectly redi…
The importance of super-Eddington black hole accretion for the emergence of massive quiescent galaxies at high redshift
Evgenii Chaikin, Joop Schaye, Filip Huško +3
Recent JWST observations indicate that massive quiescent galaxies (stellar mass ) at high redshift () are more abundant than pred…
