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…
Weighing gas-rich starless halos: dark matter parameters inference from their gas distributions
Francesco Turini, Alejandro Benitez-Llambay
Reionization-Limited Clouds (RELHICs) are starless dark matter halos retaining a significant neutral hydrogen( ) reservoir. The gas resides in near hydrostatic equil…
A subgrid model for chemical enrichment in cosmological simulations
Camila A. Correa, Joop Schaye, Matthieu Schaller +6
We present the modules for stellar nucleosynthesis, stellar mass loss, and turbulent diffusion of the new COLIBRE subgrid model for cosmological hydrodynamical simulations of galax…
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…
Non-explosive pre-supernova feedback in the COLIBRE model of galaxy formation
Alejandro BenÃtez-Llambay, Sylvia Ploeckinger, Joop Schaye +7
We present the implementation and testing of a subgrid non-explosive pre-supernova (NEPS) feedback module for the COLIBRE model of galaxy formation. The NEPS module incorporates th…
Modelling the evolution and influence of dust in cosmological simulations that include the cold phase of the interstellar medium
James W. Trayford, Joop Schaye, Camila Correa +7
While marginal in mass terms, dust grains play an outsized role in both the physics and observation of the interstellar medium (ISM). However, explicit modelling of this ISM consti…
