Abstract: 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 $1arXiv:2407.21257v1 Announce Type: new
