The diversity and variability of star formation histories in models of galaxy evolution
(2020-07-25)Understanding the variability of galaxy star formation histories (SFHs) across a range of time-scales provides insight into the underlying physical processes that regulate star formation within galaxies. We compile the ... -
Effect of the environment on star formation activity and stellar mass for star-forming galaxies in the COSMOS field
(2020-11)We investigate the relationship between the environment and the galaxy main sequence (the relationship between stellar mass and star formation rate), as well as the relationship between the environment and radio luminosity ... -
Galaxy cold gas contents in modern cosmological hydrodynamic simulations
(Oxford University Press, 2020-07-03)We present a comparison of galaxy atomic and molecular gas properties in three recent cosmological hydrodynamic simulations, namely SIMBA, EAGLE, and IllustrisTNG, versus observations from z ∼ 0 to 2. These simulations ... -
Jet feedback and the photon underproduction crisis in SIMBA
(Oxford University Press, 2020-10-01)We examine the impact of black hole jet feedback on the properties of the low-redshift intergalactic medium (IGM) in the SIMBA simulation, with a focus on the Lyα forest mean flux decrement DA. Without jet feedback, we ... -
K-CLASH: Strangulation and ram pressure stripping in galaxy cluster members at 0.3 < z < 0.6
(Oxford University Press, 2020-06-26)Galaxy clusters have long been theorized to quench the star formation of their members. This study uses integral-field unit observations from the K-band MultiObject Spectrograph (KMOS) – Cluster Lensing And Supernova ... -
MIGHTEE-HI: discovery of an HI-rich galaxy group at z = 0.044 with MeerKAT
(Monthly Notices of the Royal Astronomical Society, 2021)We present the serendipitous discovery of a galaxy group in the XMM-LSS field with MIGHTEE Early Science observations. 20 galaxies are detected in HI in this z ∼ 0.044 group, with a 3σ column density sensitivity of NHI = ... -
Timing the earliest quenching events with a robust sample of massive quiescent galaxies at 2 < z < 5
(Oxford University Press, 2020-06-04)We present a sample of 151 massive (M∗ > 1010 M) quiescent galaxies at 2 <z< 5, based on a sophisticated Bayesian spectral energy distribution fitting analysis of the CANDELS UDS and GOODS-South fields. Our sample includes ...
