Title:  Baryon Cycles in the Biggest Galaxies

Abstract:  Cycling of gas into and out of a galaxy's circumgalactic medium (CGM) sustains star formation and regulates galaxy evolution.  A break in the cycle eventually shuts star formation off.  Around most galaxies, much of the cycle is nearly invisible, but around the biggest galaxies, many of its components are observable.  I will discuss the connections between star formation, black holes, feedback, and the CGM that are emerging from studies of the baryon cycles around massive galaxies and will show how what we are learning may apply to the baryon cycles around galaxies of all masses
