Two Topics Related to Gravitational Wave Astronomy

I will discuss two topics related to compact stellar mergers and gravitational waves. 1) One of the most exciting near-term prospects in physics is the detection of gravitational waves from compact stellar mergers including neutron stars (i.e. NS-NS, NS-BH). Such mergers are the leading candidates for short gamma-ray burst progenitors. I consider a possibility that most compact stellar mergers do not produce relativistic jets, and I discuss the implications to gravitational wave astronomy. 2) The existence of black hole binaries (BH-BH) was recently revealed by the gravitational wave detectors LIGO. Their formation process is still unknown or unsettled. I will discuss an interesting formation process of compact BH binaries at galactic centers. Binary stars approaching a massive BH are expected to be tidally disrupted. However, I will show that a good fraction of such encounters produce compact binaries.

I am a Professor at Astrophysics Research Institute (ARI) at Liverpool John Moores University. Before joining ARI, I did my PhD study at Tokyo Tech, and postdoc at Osaka, Jerusalem (Hebrew Univ) and Pennsylvania (Penn State). My research mainly focuses on the hydrodynamics and radiation process of gamma-ray bursts and black hole astrophysics such as hypervelocity stars, tidal disruption events and compact stellar mergers.
