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…
The JWST EXCELS survey: The ages and abundances of massive quiescent galaxies show that downsizing was already in place by
Ho-Hin Leung, Adam C. Carnall, Elizabeth Taylor +21
We present deep, medium-resolution m JWST/NIRSpec spectroscopy for 14 quiescent galaxies at with , obtained as part of…
The JWST EXCELS Survey: gas-phase metallicity evolution at 2 < z < 8
T. M. Stanton, F. Cullen, A. C. Carnall +15
We present an analysis of the gas-phase mass-metallicity relationship (MZR) and fundamental metallicity relationship (FMR) for star-forming galaxies at from the JW…
Little Red Dots: One Photometric Tag Concealing Diverse Spectroscopic Flavors of Massive Star Formation and Black Hole Activity
Pablo G. Pérez-González, Guillermo Barro, Stefano Carniani +62
We compile JWST/NIRSpec prism and MIRI data for 249 Little Red Dots (LRDs) at 2.3<z<9.3, forming a representative spectroscopic subset of NIRCam-selected LRDs. We derive a median s…
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…
