SUMMARY:Black-hole binaries in scalar Gauss-Bonnet gravity - Helvi Witek (
 King's College London)
DTSTART:20190118T130000Z
DTEND:20190118T140000Z
UID:TALK116161@talks.cam.ac.uk
CONTACT:Nathan Johnson-McDaniel
DESCRIPTION:Despite the ever stronger observational support for general re
 lativity (GR) as our standard model of gravity\, open questions concerning
 \, e.g.\, the nature of dark matter or the reconciliation of GR with quant
 um physics persist. Most candidate theories of quantum gravity predict mod
 ifications to GR in their infra-red limit. Black holes\, and the gravitati
 onal wave signal emitted during their collision\, provide a novel way to p
 robe these underlying theories in the highly nonlinear\, dynamical regime 
 of gravity. To do so\, however\, requires accurate theoretical predictions
  of the waveforms\, an undertaking that is still in its infancy.\nIn this 
 talk I will give a review on the latest progress in ``numerical relativity
  beyond GR''\, and report\nour latest results of simulating black holes in
  Gauss-Bonnet gravity that provide the strongest observational constraints
  on this theory to-date.
