On the consistency of jet feedback modelling across different astrophysics hydrodynamical codes

N. Maragkakis, M. A. Bourne, C. Power +3

Active Galactic Nuclei (AGN) feedback is essential in cosmological simulations of galaxy formation, yet its implementation has to rely on subgrid models due to limited resolution.…

The morphologies of present-day galaxies in the COLIBRE simulations

Victor J. Forouhar Moreno, Joop Schaye, Matthieu Schaller +9

The diversity of galaxy morphologies and their relations with galaxy and halo properties is fundamental to understanding galaxy formation. Cosmological simulations of representativ…

The evolution of the sizes and angular momentum content of galaxies in the COLIBRE simulations

Aaron D. Ludlow, Katy L. Proctor, Joop Schaye +12

We analyse the sizes and specific angular momentum content of galaxies in the Colibre cosmological hydrodynamical simulations spanning two orders of magnitude in mass resolution. W…

Formation timescales for stellar bars in diverse galactic discs

Matthew Frosst, Danail Obreschkow, Aaron Ludlow

We study the formation of stellar bars using 145 simulations of disc galaxies embedded in live and static dark matter haloes. We use the exponential bar growth timescale, $τ_{\rm…

Origins and lifetimes of secular and tidal bars in simulated disc galaxies

Matthew Frosst, Danail Obreschkow, Aaron Ludlow +1

We investigate the formation of stellar bars in 307 Milky Way-mass disc galaxies in the TNG50 cosmological simulation. Most bars form rapidly in dynamically cold discs shortly afte…
