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 $lo g M_{*} / M_{⊙} > 10$ at $1 < z < 3$ with JWST/NIRSpec medium-resolution observations from the Early eXtragalactic C…

Distinct origins of environmentally quenched galaxies in the core and outer virialised regions of massive clusters at $0.8 < z < 1.5$

Guillaume Hewitt, Florian Sarron, Michael L. Balogh +15

High-redshift ( $z \sim 1$ ) galaxy clusters are the domain where environmental quenching mechanisms are expected to emerge as important factors in the evolution of the quiescent galax…

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 ( $z \sim 2$ ), using deep Chandra X-ray observations of the Ultra-Deep Survey (UDS) fi…
