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…
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…
The Three Hundred Project: deducing the stellar splashback structure of galaxy clusters from their orbiting profiles
Kris Walker, Aaron Ludlow, Chris Power +2
We examine the splashback structure of galaxy clusters using hydrodynamical simulations from the GIZMO run of The Three Hundred Project, focusing on the relationship between the st…
The weak connection between the stellar haloes and merger histories of Milky Way-mass galaxies
Katy L. Proctor, Aaron D. Ludlow, Claudia del P. Lagos +1
Stellar haloes form through the disruption of satellite galaxies over time, making them a promising observable for constraining galaxy merger histories. We use a dynamical decompos…
