Unveiling the population of massive quenched galaxies at in the COLIBRE simulations - I. Galaxy demographics

Ángel Chandro-Gómez, Claudia del P. Lagos, Chris Power +14

The James Webb Space Telescope has uncovered a substantial population of Massive (), Quenched Galaxies (MQGs) in the early Universe ($z \ge…

The excess of molecular hydrogen in chemical networks without oxygen

Sylvia Ploeckinger

We report the presence of a systematic excess in the molecular hydrogen fraction () in studies that use a reduced chemistry n…

Kennicutt-Schmidt relation of galaxies over 13 billion years in the COLIBRE hydrodynamical simulations

Claudia del P. Lagos, Joop Schaye, Matthieu Schaller +16

We investigate the correlation between star formation rate (SFR) surface density and gas surface density (known as the Kennicutt-Schmidt, KS, relation) at kiloparsec (kpc) scales a…

Dynamical disequilibrium in dwarf galaxies: rethinking gas dynamics, rotation curves, and dark matter inference

Diego Dado, Kyle A. Oman, Katherine E. Harborne +9

We quantify departures from hydrodynamical and centrifugal equilibrium in the gas discs of low-mass () galaxies from the COLIBR…

LYRA ultra-faints: The emergence of faint dwarf galaxies in the presence of an early Lyman-Werner background

Shaun T. Brown, Azadeh Fattahi, Thales A. Gutcke +6

We present a suite of zoom-in cosmological hydrodynamical simulations of dwarf galaxies using the LYRA galaxy formation model with an extremely high mass resolution of $4\, \mathrm…

Gravitational potential drives the concentration dependence of the stellar mass-halo mass relation

Kai Wang, Joop Schaye, Alejandro Benítez-Llambay +8

We investigate the origin of the scatter in the stellar mass-halo mass (SMHM) relation using the \colibre cosmological hydrodynamical simulations. At fixed halo mass, we find a cle…
