Observing the sites of massive binaries and recoiling black holes - electromagnetic signatures

Abstract:   The presence of binary supermassive black holes, and the recoiling single black holes that they sometimes produce, has potentially important implications for many branches of astrophysics, including cosmological structure formation, black hole growth, and feedback processes and the evolution of AGN activity. Merging black holes are laboratories which enable us to test theories of gravity and to study the effects of strong gravity on matter. The electromagnetic signatures of coalescing and recoiling black holes are signposts of merger events and provide tight new constraints on merger histories. I will provide an overview of these signatures including future schemes to search for the electromagnetic counterparts to merging and ejected black holes, and will discuss some astrophysical implications.
