Research Abstract

In this research project, we consider gravitational waves produced by the inspirals of compact binaries and a compact star inspiraling into massive black hole. We performed accurate numerical computation of htose gravitational waves, and developed analytical model of waveforms. We also considerde the optimal data analysis strategy for the network of gravitational wave detectors including the Japanese detector. We evaluated the detection efficiency and parameter estimation accuracy by using the optimal date analysis strategy.
