JWST PRIMER: Post-starburst galaxies dominate the low-mass quiescent galaxy population since z~2
Thomas de Lisle, David T. Maltby, Omar Almaini +10
We present the evolution of the stellar mass functions for photometrically selected star-forming, passive and post-starburst galaxies, based on JWST PRIMER observations of the Ultr…
No hidden monsters: Probing recently-quenched galaxies for obscured AGN with JWST-PRIMER MIRI and NIRCam
Guillaume Hewitt, Omar Almaini, David Maltby +13
We investigate the role of obscured active galactic nuclei (AGN) in recently quenched post-starburst galaxies (PSBs), using a sample of 65 photometrically selected PSBs in the PRIM…
The JWST EXCELS survey: Insights into the nature of quenching at cosmic noon
Maya Skarbinski, Kate Rowlands, Katherine Alatalo +19
We study 24 massive quiescent galaxies with at with JWST/NIRSpec medium-resolution observations from the Early eXtragalactic C…
The role of mergers and rejuvenation in the buildup of the quiescent population at cosmic noon
Jimi Evan Harrold, Omar Almaini, Frazer R. Pearce +6
We investigate the quenching of galaxies using a mock observational lightcone generated from the Semi-Analytic Model (SAM) L-Galaxies, closely matched to observations from the UKID…
No evidence for excess AGN activity in recently quenched massive galaxies at cosmic noon
Omar Almaini, Vivienne Wild, David Maltby +8
We present an analysis of AGN activity within recently quenched massive galaxies at cosmic noon (), using deep Chandra X-ray observations of the Ultra-Deep Survey (UDS) fi…
