"Do Supermassive Black Holes Help to Regulate Galaxy Evolution and"

Supermassive black holes that are rapidly accreting matter (and sometimes outshining their host galaxies) were the first sources discovered at cosmological redshifts. Despite progress in the intervening half-century, key questions remain about how black holes affect the evolution of their host galaxies, as well as how they self-regulate their own growth. I will discuss so-called "AGN feedback," which is a topic of intense theoretical and observational interest. I will focus in particular on what we are learning from multiwavelength observational studies of the nearest and brightest active galactic nuclei.
