  Title: Gravitational waves from extreme mass ratio inspirals 

  Speaker: Dr. Jiang Long (龙江)(Universite Libre de Bruxelles) 

  Time: 3:00PM, June 5th, 2018 (Tuesday) 

  Place: Theoretical Physics Division, 319 

  Abstract: We analytically compute time domain gravitational waveforms produced in the final stages of extreme mass ratio inspirals of non-spinning compact objects into supermassive nearly extremal Kerr black holes. The resulting gravitational waveforms consist of an intermediate polynomial ringdown phase followed by an exponential quasi-normal mode decay. The waveform amplitude exhibits critical behavior when the orbital angular momentum tends to a minimal value determined by the innermost stable circular orbit. We show that either near-critical or large angular momentum leads to a significant extension of gravitational wave observation.
