Despite remarkable success at modeling the evolution of massive galaxies over cosmic time, modern hydrodynamic and semi-analytic models of galaxy formation fail to reproduce the properties of low-mass galaxies. This shortcoming in our theoretical picture is largely driven by an inability to understand the physical mechanisms by which star formation is suppressed (or “quenched”) in satellite galaxies. In an effort to address this shortcoming, I will present results — produced over the past 7 years at UCI — that measure the efficiency of satellite quenching over the full range of satellite mass scales at z ~ 0 and produce a coherent physical picture for satellite galaxy evolution at late cosmic times.
