SQuIGGLE: Radio AGN Found Predominantly in Young, Gas-rich Post-starburst Galaxies at z ~ 0.7
Vincenzo R. D'Onofrio, Justin S. Spilker, Krista L. Smith +13
The processes that rapidly quench massive galaxies and maintain their quiescence remain poorly understood. Substantial molecular gas reservoirs can survive this shutdown in post-st…
Unveiling the Origins of the Molecular Gas Reservoirs in Recently Quenched Massive Galaxies
E. Savitch, D. Narayanan, D. J. Setton +13
Observations of quenched galaxies across cosmic time have revealed systems containing substantial molecular gas reservoirs, challenging the traditional picture of gas-poor, red and…
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…
SQuIGGE: Spatially resolved NIRSpec Pa reveals that the most CO-luminous, post-starburst galaxies exhibit falling---but still active---star formation behind optically thick dust
David J. Setton, Jenny E. Greene, Rachel Bezanson +13
One of the fundamental uncertainties in the study of galaxies at the interface between star formation and quiescence--post-starburst galaxies--is their instantaneous star formation…
Caught Napping by JWST UNCOVER+MegaScience: Constraining bursty star formation histories and number densities of mini-quenched galaxies at redshifts 4-7
Gourav Khullar, Rachel Bezanson, Katherine A. Suess +27
We explore the prevalence of mini-quenched or ``napping'' galaxies selected from spectroscopic and photometric samples in the UNCOVER/MegaScience survey. These galaxies are empiric…
Toward Unbreaking the Universe: MINERVA Measurements of Color Gradients in Massive Quiescent Galaxies Can Help Ease Too-Early Star Formation Tensions
Sam E. Cutler, Luke Robbins, Danilo Marchesini +41
The discovery of a population of massive, ancient quiescent galaxies within the first 2 Gyr of the Universe's history has led to significant tensions with models of galaxy formatio…
Everything Every Band All at Once I: A Global Morphology Catalog in Abell 2744 based on UNCOVER/MegaScience
Yunchong Zhang, Tim B. Miller, Sedona H. Price +31
We present spectrally-resolved structural parameter measurements of 28,274 sources from the legacy lensing field of Abell 2744, quantifying global structures from observed $0.7 μm…
Evidence for Shallow Nebular Attenuation Curves and Patchy Dust Geometry at z~2 with Pa-beta/H-alpha Measurements from JWST-MegaScience Medium Band Photometry
Brian Lorenz, Katherine A. Suess, Mariska Kriek +25
We constrain the nebular attenuation curve and investigate dust geometry in star-forming galaxies at cosmic noon using photometric medium-band emission line measurements. We measur…
Molecular Gas Excitation in z ~ 0.7 Gas-Rich Post-starburst Galaxies from SQuIGGLE
Vincenzo R. D'Onofrio, Justin S. Spilker, Rachel Bezanson +10
Many post-starburst galaxies at have been shown to retain substantial molecular gas reservoirs yet host low ongoing star formation, suggesting that the remaining gas may…
It's More Complicated Than You Think: A Forward Model to Infer the Recent Star Formation History, Bursty or Not, of Galaxy Populations
Emilie Burnham, Bingjie Wang, Joel Leja +14
Observations of the early Universe (z > 4) with the James Webb Space Telescope reveal galaxy populations with a wide range of intrinsic luminosities and colors. Bursty star formati…
UNCOVER/MegaScience Finds Uniform and Highly Bursty Star Formation at 3 < z < 9, consistent with the High-Redshift UV Luminosity Function
Ikki Mitsuhashi, Katherine A. Suess, Joel Leja +24
Star formation timescales are key to understanding fundamental physics like feedback mechanisms, as well as the abundance of bright galaxies at . We investigate galaxy star f…
Hidden mass in early galaxies revealed by bottom-heavy initial mass functions
Chloe M. Cheng, Martje Slob, Mariska Kriek +21
James Webb Space Telescope (JWST) observations have revealed that massive galaxies formed and evolved faster than predicted by galaxy formation models, with many having already ass…
