"Formation and Growth of Massive Black Holes"

A Pretty Image from the Talk

Abstract:

I will review how massive black holes may have formed in the early universe from stellar-mass black hole remnants, via super-Eddington accretion, or run-away mergers of stellar-mass objects. I will then discuss mergers between supermassive black holes, particularly the role that circumbinary gas plays during thes mergers for facilitating (or not) the early inspiral, producing unique electromagnetic signatures, and impacting low-frequency gravitational waves.
