DESI Massive Post-Starburst Galaxies at \mathbf{z\sim1.2} have compact structures and dense cores

By Yunchong Zhang and others
Post-starburst galaxies (PSBs) are young quiescent galaxies that have recently experienced a rapid decrease in star formation, allowing us to probe the fast-quenching period of galaxy evolution. In this work, we obtained HST WFC3/F110W imaging to measure the sizes of 171 massive (\mathrm{log(M_{*}/M_{\odot})\sim\,11)} spectroscopically identified PSBs at 1<z<1.3 selected from... Show more
