Comparing galaxy clustering in horizon-agn simulated light-cone mocks and video observations
(Oxford University Press, 2019-04-12)Hydrodynamical cosmological simulations have recently made great advances in reproducing galaxy mass assembly over cosmic time – as often quantified from the comparison of their predicted stellar mass functions to observed ... -

Disturbed, diffuse, or just missing? A global study of the H I content of Hickson compact groups
(EDP Sciences, 2023)Context. Hickson compact groups (HCGs) are dense configurations of four to ten galaxies, whose H I morphology appears to follow an evolutionary sequence of three phases, with gas initially confined to galaxies, then ... -
IQ-Collaboratory 1.1: The Star-forming Sequence of Simulated Central Galaxies
(The astrophysical journal, 2019)A tightly correlated star formation rate (SFR)–stellar mass relation of star-forming galaxies, or star-forming sequence (SFS), is a key feature in galaxy property-space that is predicted by modern galaxy formation models. ... -
Mergers, starbursts, and quenching in the SIMBA simulation
(MNRAS, 2019-07-29)We use the SIMBAcosmological galaxy formation simulation to investigate the relationship between major mergers ( 4:1), starbursts, and galaxy quenching. Mergers are identified via sudden jumps in stellar mass M∗ well ... -
Semi-analytic forecasts for jwst – ii. Physical properties and scaling relations for galaxies at z = 4–10
(Oxford academic, 2019)The long anticipated James Webb Space Telescope (JWST) will be able to directly detect large samples of galaxies at very high redshift. Using the well-established, computationally efficient Santa Cruz semi-analytic model, ... -
Semi-analytic forecasts for JWST – IV. Implications for cosmic reionization and LyC escape fraction
(Oxford University Press, 2020-06-20)Galaxies forming in low-mass haloes are thought to be primarily responsible for reionizing the Universe during the first billion years after the big bang. Yet, these haloes are extremely inefficient at forming stars in ... -
The vandels survey: The star-formation histories of massive quiescent galaxies at 1.0 < z < 1.3
(Oxford Academics, 2019)We present a Bayesian full-spectral-fitting analysis of 75 massive (M∗>1010.3M⊙) UVJ-selected galaxies at redshifts of 1.0 < z < 1.3, combining extremely deep rest-frame ultraviolet spectroscopy from VANDELS with ... -
X-ray emission from hot gas in galaxy groups and clusters in SIMBA
(Oxford University Press, 2020-08-31)We examine X-ray scaling relations for massive haloes (M500 > 1012.3 M) in the SIMBA galaxy formation simulation. The X-ray luminosity, LX versus M500 has power-law slopes ≈5 3 and ≈8 3 above and below 1013.5 M, deviating ...
