z~1.5 Time of quenching for cluster galaxies? What is the morphology of the star-forming galaxies? How big are they? Do they quench faster than the field galaxies? Brodwin et al. 2013; Alberts et al.2016

Are star-bursts the way to quenching? Or is it mergers? Or violent gas cooling? Compaction? Fast or slow? Zolotov et al. 2015
