DESI Survey Validation Spectra Reveal an Increasing Fraction of Recently Quenched Galaxies at
David J. Setton, Biprateep Dey, Gourav Khullar +24
We utilize bright Luminous Red Galaxies (LRGs) from the novel Dark Energy Spectroscopic Instrument Survey Validation spectroscopic sample, leveraging its deep ($\sim2.5…
The JWST UNCOVER Treasury survey: Ultradeep NIRSpec and NIRCam ObserVations before the Epoch of Reionization
Rachel Bezanson, Ivo Labbe, Katherine E. Whitaker +40
In this paper we describe the survey design for the Ultradeep NIRSpec and NIRCam ObserVations before the Epoch of Reionization (UNCOVER) Cycle 1 \JWST Treasury program, which execu…
Merger Signatures are Common, but not Universal, In Massive, Recently-Quenched Galaxies at z~0.7
Margaret Verrico, David J. Setton, Rachel Bezanson +9
We present visual classifications of merger-induced tidal disturbances in 143 post-starburst galaxies at z0.7 identified in the SQuIGG$\ve…
Star Formation Suppresion by Tidal Removal of Cold Molecular Gas from an Intermediate-Redshift Massive Post-Starburst Galaxy
Justin S. Spilker, Katherine A. Suess, David J. Setton +7
Observations and simulations have demonstrated that star formation in galaxies must be actively suppressed to prevent the formation of over-massive galaxies. Galactic outflows driv…
Schrodinger's Galaxy Candidate: Puzzlingly Luminous at , or Dusty/Quenched at ?
Rohan P. Naidu, Pascal A. Oesch, David J. Setton +22
's first glimpse of the Universe has yielded a surprising abundance of luminous galaxy candidates. Here we present the most extreme of these systems: CEERS-1749. Based…
JWST reveals a population of ultra-red, flattened disk galaxies at 2<z<6 previously missed by HST
Erica J. Nelson, Katherine A. Suess, Rachel Bezanson +19
With just a month of data, JWST is already transforming our view of the Universe, revealing and resolving starlight in unprecedented populations of galaxies. Although ``HST-dark" g…
Recovering the star formation histories of recently-quenched galaxies: the impact of model and prior choices
Katherine A. Suess, Joel Leja, Benjamin D. Johnson +7
Accurate models of the star formation histories (SFHs) of recently-quenched galaxies can provide constraints on when and how galaxies shut down their star formation. The recent dev…
Rest-frame near-infrared sizes of galaxies at cosmic noon: objects in JWST's mirror are smaller than they appeared
Katherine A. Suess, Rachel Bezanson, Erica J. Nelson +10
Galaxy sizes and their evolution over cosmic time have been studied for decades and serve as key tests of galaxy formation models. However, at these studies have been l…
Two Remarkably Luminous Galaxy Candidates at Revealed by JWST
Rohan P. Naidu, Pascal A. Oesch, Pieter van Dokkum +22
The first few hundred Myrs at mark the last major uncharted epoch in the history of the Universe, where only a single galaxy (GNz11 at ) is currently spectroscop…
The Compact Structures of Massive Post-Starburst Galaxies in the SQuIGGE Sample
David J. Setton, Margaret Verrico, Rachel Bezanson +9
We present structural measurements of 145 spectroscopically selected intermediate-redshift (z0.7), massive () post-starburst galaxies from the…
