Searching for Dual AGN
Abstract
I will discuss the search for binary black holes using active galaxies. I will discuss searches for systems on kpc scales (so-called "dual" active galactic nuclei or AGN). These searches have used both spectroscopic and photometric methods, and they suggest that dual AGN are quite rare. Then I will zoom into the "final parsec" and discuss new observational constraints on sub-pc--scale binaries.
