SQuIGGE: Ubiquitous Cool Gas Outflows with Large Mass-Loading Factors in Post-starburst Galaxies

Yuanze Luo, Justin S. Spilker, David J. Setton +13

While recent James Webb Space Telescope studies have highlighted cool gas outflows as an important mechanism for rapid quenching at , such space-based spectroscopic samp…

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 multiwavelength structure of post-starburst galaxies at 0.5 < z < 3 with JWST PRIMER: compact morphologies and residual disturbances

David T. Maltby, Omar Almaini, Vivienne Wild +9

We investigate the multi-wavelength structure of recently quenched post-starburst (PSB) galaxies at 0.5 < z < 3, using photometrically selected samples from the Ultra Deep Survey (…

Unprecedented Constraints on Gas Flows at High Redshift Using Deep JWST/NIRSpec Observations from the LyC22, EXCELS, and AURORA Surveys

Emily Kehoe, Alice E. Shapley, Adam C. Carnall +25

We investigate how low-ionization gas flows in typical star-forming galaxies at depend on galaxy intrinsic properties and viewing angle. For this analysis we use JWST/NIRS…

The JWST EXCELS survey: Outflows in 1.5 < z < 5 quiescent and recently quenched galaxies are likely relics from episodic AGN activity

Elizabeth Taylor, Adam C. Carnall, David Maltby +24

We investigate the presence and origin of neutral gas outflows and inflows in 13 post-starburst (PSB) and quiescent galaxies at redshifts 1.8 z 4.6, using JWST NIRSpe…

High-velocity outflows persist up to 1 Gyr after a starburst in recently-quenched galaxies at z > 1

Elizabeth Taylor, David Maltby, Omar Almaini +4

High-velocity outflows are ubiquitous in star-forming galaxies at cosmic noon, but are not as common in passive galaxies at the same epoch. Using optical spectra of galaxies select…

The role of mass and environment in the build up of the quenched galaxy population since cosmic noon

E. Taylor, O. Almaini, M. Merrifield +4

We conduct the first study of how the relative quenching probability of galaxies depends on environment over the redshift range , using data from the UKIDSS Ultra-Deep…
