Event Details

One of the most important realizations of the past fifteen years is the vital role that feedback processes must play in the evolution of galaxies, particularly at the massive end. Beginning already within the first 2Gyr of the history of the universe, star formation in massive galaxies appears to be efficiently and rapidly shut off (“quenched”) as they transition to the red sequence. I will discuss ongoing efforts to understand the causes and effects of galaxy quenching, focusing on three populations from z ~ 1-6. In each case I will argue that unique insights can be gained from observing the molecular gas, ranging from connections to local quiescent galaxies to directly observing feedback in action. The ultimate goal of these studies is to understand the mechanisms, direction, and consequences of feedback processes in galaxies, and I will outline areas where significant progress can be made from next-generation observatories.
