Relativistic Astrophysics, Numerical Relativity and Gravitaitonal Wave Physics

Research Interest
Binary black holes and neutron stars in a close orbit, and a largely deformed rapidly rotating compact object, are strong gravitational wave sources, which may be detectable by the interferometric dectors on the ground (LIGO/VIRGO/GEO600/TAMA) and in the space (LISA/DECIGO). Accurate knowledge of such compact objects is crucial to develop theoretical models for associated gravitational waveforms that enhance the chances for detecting the signal in the noisy output of the laser interferometers. We have been developing new formulation and numerical method for computing quasi-equilibriums solutions of such systems, which are used as initial data sets for accurate simulations of numerical relativity, and sources to produce gravitational wave templates.
