COLIBRE simulations find the galaxy gas-phase MZR already in place at z≈10 with little evolution until z≈5, then shallowens at low z, with high-mass turnover set by AGN feedback and low-mass end by core-collapse supernovae.

In COLIBRE, today's galaxy morphology is set mostly by stellar mass: galaxies near M*≈1–2×10^10 M⊙ are the most disc-dominated, above ~2×10^11 M⊙ everything is spheroidal, and halo properties matter only weakly at fixed mass.
COLIBRE simulations underpredict bright-end UV galaxy luminosities by 1 to 2.5 magnitudes at z=7-15 compared with observations, with the discrepancy persisting after dust attenuation and uncertainty accounting.
COLIBRE simulations with SKIRT post-processing match observed galaxy luminosity functions from FUV to submm at z=0, except underpredicting bright mid-IR galaxies.
