Where Galaxies Go to Die: The Environments of Massive Quiescent Galaxies at
Ian McConachie, Anna de Graaff, Michael V. Maseda +25

Cold gas in a post-starburst pair at z ~ 1.4: major mergers as a pathway to quenching in the HeavyMetal survey
Katherine A. Suess, Aliza G. Beverage, Mariska Kriek +12
Recent observations at low redshift have revealed that some post-starburst galaxies retain significant molecular gas reservoirs despite low ongoing star formation rates, challengin…
Taking a Break at Cosmic Noon: Continuum-selected Low-mass Galaxies Require Long Burst Cycles
Abby Mintz, David J. Setton, Jenny E. Greene +25
While bursty star formation in low-mass galaxies has been observed in local populations and reproduced in simulations, the dormant phase of the burst cycle has not been well studie…
