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…

Columba: isolated dwarf galaxy populations in diverse cosmological environments simulated with a cold interstellar medium

Jemima M. Briggs, Azadeh Fattahi, Robert A. Crain +7

We introduce a suite of LambdaCDM cosmological, hydrodynamical simulations that track the evolution of a large population of dwarf galaxies. The suite comprises zoom-in simulations…

The galaxy ultraviolet luminosity function from to in the COLIBRE simulations

Shengdong Lu, Carlos S. Frenk, Cedric G. Lacey +17

JWST has enabled the detection of galaxies in the earliest stages of cosmic history. We compare the ultraviolet luminosity functions (UVLFs) at redshifts predicted by the…

Galaxy luminosity functions from far-UV to submillimetre at in the COLIBRE simulations

Shengdong Lu, Carlos S. Frenk, Cedric G. Lacey +15

We present predictions from the recent COLIBRE cosmological hydrodynamical simulations of galaxy formation for the present-day galaxy luminosity functions (LFs) at wavelengths rang…

Galaxy discs regulate the growth of supermassive black holes

Ryan J. Roberts, Jonathan J. Davies, Robert A. Crain

We examine the relationship between the mass of present-day central supermassive black holes (SMBHs, ), and the stellar mass () and halo mass () of…

COLIBRE: calibrating subgrid feedback in cosmological simulations that include a cold gas phase

Evgenii Chaikin, Joop Schaye, Matthieu Schaller +17

We present the calibration of stellar and active galactic nucleus (AGN) feedback in the subgrid model for the new COLIBRE hydrodynamical simulations of galaxy formation. COLIBRE di…
