Open House Lecture - Erin Bonning (Emory University)
Supermassive black holes: jets, disks, and kicksSupermassive black holes (i.e. those with millions to billionstimes the mass of the sun) are found at the heart of nearly every massivegalaxy. They are the engine that drives luminous quasars, and they seem to playa critical, though still mysterious, role in galaxy evolution. Supermassiveblack holes acquire their bulk through two routes: mergers and accretion. In a subset of galaxies, the accretion process is actively ongoing: a hotdisk of matter falls into the black hole, and, for reasons yet unknown,powerful relativistic jets of particles are occasionally launched into theintergalactic medium. I will discuss three active areas of research into theseprocesses. First, what we can learn from gamma-ray bright active galaxieswith jets, second, how black holes may regulate the formation of stars ingalaxies, and finally, searches for binary black hole mergers from which theblack hole is expected to be ejected from its host galaxy.
