Title: Using Supermassive Black Holes to Trace the Evolution of Galaxies
Abstract: Supermassive black holes, which are a million to a billion times more massive than the Sun, lie at the centers of massive galaxies. When two galaxies merge, their two supermassive black holes also inspiral and merge, and in the process they may accrete gas and become visible as bright active galactic nuclei (AGN). These inspiralling AGN are excellent tracers of the galaxy merger itself and the mass growth of the black hole, but they have proven difficult to observe. I will present a new observational approach to finding inspiralling AGN, and discuss what these objects reveal about how galaxy mergers trigger black hole mass growth.
