Abstract: We study 24 massive quiescent galaxies with $log textrm{M}_*/textrm{M}_odot > 10$ at $1 10.7$) exhibiting shorter visibility times than lower mass galaxies. The range of quenching times — defined as the time from the peak starburst to the time of quiescence — found in this sample ($0.06-1.75$ Gyr) suggests multiple quenching pathways, consistent with previous studies. We do not see evidence for quenching mechanisms varying with redshift between $1
