Time: 2:30 - 4:30pm
Speaker: Helvi Witek
Venue: G. O. Jones Building, Room 610

Despite the ever stronger observational support for general relativity (GR) as our standard model of gravity, open questions concerning, e.g., reconciliation of GR with quantum physics indicate the existence of a more fundamental theory of quantum gravity. While the exact theory is unknown, most candidate theories of quantum gravity predict modifications to GR. Black holes, and the gravitational wave signal emitted during their collision, provide a novel way to search for signatures of these underlying theories. To do so, however, requires accurate theoretical predictions of the waveforms, an undertaking that is still in its infancy. In this talk I will give a review on the latest progress in ``numerical relativity beyond GR'', and report on new results of simulating black holes in Gauss-Bonnet gravity that provide the strongest observational constraints on this theory to-date.
