Quasar Sightline and Galaxy Evolution (QSAGE) -- III. The mass-metallicity and fundamental metallicity relation of 2.2 galaxies
H. M. O. Stephenson, J. P. Stott, F. Cullen +8
We present analysis of the mass-metallicity relation (MZR) for a sample of 67 [OIII]-selected star-forming galaxies at a redshift range of ()…
The impact of free-streaming on dwarf galaxy counts in low-density regions
Tamar Meshveliani, Mark R. Lovell, Robert A. Crain +1
We study the statistics of dwarf galaxy populations as a function of environment in the cold dark matter (CDM) and warm dark matter (WDM) cosmogonies, using hydrodynamical simulati…
Realistic simulated galaxies form [/Fe]-[Fe/H] knees due to a sustained decline in their star formation rates
Andrew C. Mason, Robert A. Crain, Ricardo P. Schiavon +5
We examine the stellar [/Fe]-[Fe/H] distribution of present-day galaxies in a high-resolution EAGLE simulation. A slight majority of galaxies exhibit the canonical…
Hydrodynamical simulations of the galaxy population: enduring successes and outstanding challenges
Robert A. Crain, Freeke van de Voort
We review the progress in modelling the galaxy population in hydrodynamical simulations of the Lambda-CDM cosmogony. State-of-the-art simulations now broadly reproduce the observed…
Mapping the imprints of stellar and AGN feedback in the circumgalactic medium with X-ray microcalorimeters
Gerrit Schellenberger, Ákos Bogdán, John A. ZuHone +24
The Astro2020 Decadal Survey has identified the mapping of the circumgalactic medium (CGM, gaseous plasma around galaxies) as a key objective. We explore the prospects for characte…
In-situ or accreted? Using deep learning to infer the origin of extragalactic globular clusters from observables
Sebastian Trujillo-Gomez, J. M. Diederik Kruijssen, Joel Pfeffer +4
Globular clusters (GCs) are powerful tracers of the galaxy assembly process, and have already been used to obtain a detailed picture of the progenitors of the Milky Way. Using the…
