제목 : Compact binaries as gravitational-wave sources

연사 : 김정리 박사님 (한국천문연구원)

 

요약

 Compact binary coalescences (CBCs) consisting of neutron stars  (NSs) or stellar-mass black holes (BHs) are expected to be strong sources of gravitational waves (Gws). They are the most promising targets for the km-scale laser interferometers on Earth. The predicted detection rates for gravitational waves are based on modeling of the Galactic NS and BH binary population and detector sensitivity. When routine detections will be made, GWs provide independent probes to explore these exotic objects in addition to the photon- or particle-based observations. The advanced LIGO (USA) will start its first "observational run" on September 14th, 2015. This is the first detector that is capable to detect CBCs in cosmic distance scale via GWs. In this talk, I will give an overview on the international effort in GW detection. Focusing on compact binaries, I will also discuss implications of GW detections and prospects for multi-messenger astronomy.
