TAP Colloquium: Dr. Aaron Zimmerman
Black Holes, Alone and in Pairs

The recent detections of gravitational waves have revealed an invisible side of the uni-verse: black holes in binaries. These observations test our understanding of black holes, their violent mergers, and the theory of general relativity. A combination of an-alytic approximations and full numerical simulations is required to understand black hole binaries and predict the gravitational waves they emit. I will take us on a tour of these systems, discuss the "ringdown" of the final merged black hole, and present the most recent results from the Advanced LIGO and Virgo detectors.
