Two Distinct Classes of Quiescent Galaxies at Cosmic Noon Revealed by JWST PRIMER and UNCOVER
Using the JWST UNCOVER and PRIMER Treasury surveys, we measure the sizes of 332 7<logM<11 quiescent galaxies at cosmic noon (1<z<3). We find that there exist two distinct populations of quiescent galaxies at this epoch: a young, low-mass, disky population and an older, massive, spheroidal population, further highlighting the different mechanisms involved in galaxy evolution at low masses.

Diagnosing DASH: A Catalog of Structural Properties for the COSMOS-DASH Survey
We present an HST-resolution morphological catalog of over 50,000 galaxies in the COSMOS field utilizing the “Drift And SHift” (DASH) observing mode. We test the limits of DASH observations for determining morphologies of galaxies across a wide range of masses and redshifts.
