The COLIBRE project: cosmological hydrodynamical simulations of galaxy formation and evolution
Joop Schaye, Evgenii Chaikin, Matthieu Schaller +18
We present the COLIBRE galaxy formation model and the COLIBRE suite of cosmological hydrodynamical simulations. COLIBRE includes new models for radiative cooling, dust grains, star…
Sub-millimeter galaxies in hierarchical models: revisiting the need for a top-heavy stellar initial mass function with Bayesian optimisation
Edward Elliott, C. M. Baugh, Cedric Lacey
The properties of high-redshift sub-millimetre galaxies (SMGs) remain controversial within hierarchical structure formation models. We revisit whether a top-heavy stellar initial m…
First Light And Reionisation Epoch Simulations (FLARES) XX: Comparing semi-analytic models at high-redshift
Louise T. C. Seeyave, Carlton M. Baugh, Angel Chandro-Gomez +13
We explore how the choice of galaxy formation model affects the predicted properties of high-redshift galaxies. Using the FLARES zoom resimulation strategy, we compare the EAGLE hy…
A random walk model for the evolution of the halo spin vector
Jun Hou, Zhijian Luo, Cedric G. Lacey
We follow the spin vector evolutions of well resolved dark matter haloes (containing more than 300 particles) in merger tree main branches from the Millennium and Millennium-II N-b…
On the accuracy of dark matter halo merger trees and the consequences for semi-analytic models of galaxy formation
Ãngel Chandro-Gómez, Claudia del P. Lagos, Chris Power +6
Galaxy formation and evolution models, such as semi-analytic models, are powerful theoretical tools for predicting how galaxies evolve across cosmic time. These models follow the e…
The effects of super-Eddington accretion and feedback on the growth of early supermassive black holes and galaxies
Filip Huško, Cedric G. Lacey, William J. Roper +3
We present results of cosmological zoom-in simulations of a massive protocluster down to redshift (when the halo mass is M) using the SWIFT cod…
