Accretion Dynamics into Relativistic Binary Black Hole Mergers

Multi-messenger astronomy promises to revolutionize our understanding of the universe by providing dramatically contrasting views of the same objects. Black holes are the most fascinating and ubiquitous objects in the universe. Unlike stellar-mass black holes, it is generally expected that supermassive black holes lurking at the center of most galaxies will merge in a gas rich environments, because galaxies merge from time to time. Until an orbiting gravitational wave observatory is operational, the best way to discover such systems is by the photons they emit. In this talk, I will review the history of simulation efforts to model binary black holes in their astrophysical environments. I will also present some exciting new results in the context of magneto-hydrodynamics simulation, indicating that supermassive binary black hole sources might be also detectable in the electromagnetic spectrum in the not too distant future.

Followed by wine and cheese in Pupin 1332.
