Title: Tracing Galaxy Evolution with Observations of Dual Supermassive Black Holes

Abstract: Galaxy mergers produce kpc-scale separation dual supermassive black holes, which are the smallest separation supermassive black hole pairs yet confirmed. These dual supermassive black holes, which will ultimately become black hole binaries and merge, are useful as direct observational tracers of galaxy evolution. I will describe a systematic survey of dual supermassive black holes, where we observe these systems when one or both of the black holes powers an active galactic nucleus (AGN). Using multiwavelength observations in radio, near infrared, optical, and X-ray, we are able to build up the first large catalog of dual supermassive black holes. I will present the results of this campaign, including insights into merger-fueled AGN activity.
