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…

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…

The role of galactic winds fueling central starbursts and quasars in the FIRE cosmological simulations

Jonathan Mercedes-Feliz, Daniel Anglés-Alcázar, Boon Kiat Oh +7

Central starbursts and Active Galactic Nuclei (AGN) are thought to be fueled by either galaxy interactions or secular processes in gravitationally unstable discs. We employ cosmolo…

Emission line tracers of galactic outflows driven by stellar feedback in simulations of isolated disk galaxies

Elliot L. Howatson, Alexander J. Richings, Elke Roediger +7

Hydrodynamic simulations can connect outflow observables to the physical conditions of outflowing gas. Here, we use simulations of isolated disk galaxies ranging from dwarf mass ($…

Non-explosive pre-supernova feedback in the COLIBRE model of galaxy formation

Alejandro Benítez-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…

The HyLight model for hydrogen emission lines in simulated nebulae

Yuankang Liu, Tom Theuns, Tsang Keung Chan +2

Hydrogen recombination lines provide key diagnostics of ionized gas in galaxies, yet most hydrodynamical simulations estimate hydrogen level populations using interpolated emissivi…

The evolution of the galaxy stellar mass function and star formation rates in the COLIBRE simulations from redshift 17 to 0

Evgenii Chaikin, Joop Schaye, Matthieu Schaller +7

We investigate the evolution of the galaxy stellar mass function (GSMF) and star formation rates (SFRs) across cosmic time in the COLIBRE simulations of galaxy formation. COLIBRE i…

A hybrid active galactic nucleus feedback model with spinning black holes, winds and jets

Filip Huško, Cedric G. Lacey, Joop Schaye +6

We present a hybrid active galactic nucleus (AGN) feedback model that features three accretion disc states (the thick, thin, and slim discs at low, moderate, and super-Eddington ac…

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…
