Discovery of Ancient Globular Cluster Candidates in the Relic, a Quiescent Galaxy at

Katherine E. Whitaker, Sam E. Cutler, Rupali Chandar +31

Globular clusters (GCs) are some of the oldest bound structures in the Universe, holding clues to the earliest epochs of star formation and galaxy assembly. However, accurate age m…

JWST+ALMA reveal the build up of stellar mass in the cores of dusty star-forming galaxies at Cosmic Noon

Sarah Bodansky, Katherine E. Whitaker, Ayesha Abdullah +14

Dusty star-forming galaxies have long been suspected to serve as the missing evolutionary bridge between the star-forming and quiescent phases of massive galaxy evolution. With the…

Taking a Break at Cosmic Noon: Continuum-selected Low-mass Galaxies Require Long Burst Cycles

Abby Mintz, David J. Setton, Jenny E. Greene +25

While bursty star formation in low-mass galaxies has been observed in local populations and reproduced in simulations, the dormant phase of the burst cycle has not been well studie…

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…

Water absorption confirms cool atmospheres in two little red dots

Bingjie Wang, Joel Leja, Ivo Labbe +35

Little red dots (LRDs) are an abundant population of compact high-redshift sources with red rest-frame optical continua, discovered by the James Webb Space Telescope (JWST). Their…
