Some of the greatest outstanding questions in the study of galaxies involve how galaxies transition from star-forming to quiescent, and what processes act to shut down star formation and keep it suppressed. Both multi-wavelength observations and simulations have made great progress in identifying mechanisms to “quench” star formation across a variety of conditions. However, many questions remain about how the proposed mechanisms act in real galaxies, given the complexities of their multi-phase reservoirs for star-forming and potentially star-forming gas.

A growing body of research suggests that the “quenching” of galaxies, the point when their star formation ends, does not mark the end of their gas evolution. This had led to further questions, such as (1) What happens in the billion years between quenching and the end quiescent product? (2) What suppresses star formation during this phase? (3) How is star-forming gas cleared away from galaxies? (4) How does this process proceed spatially within and around a galaxy? And (5), How do these processes depend on redshift, stellar mass, and environment?

We propose a workshop to gather observers and simulators across the fields of star formation, active galactic nuclei, and evolution through the quenching phase in order to foster cross-discipline communication and plan observational and computational projects to investigate these issues.
