Developing a statistical method of gravitational wave data analysis for tests of gravity
A gravitational wave is distortion of spacetime that is theoretically predicted in general relativity and propagates with speed of light. In September 2015, a gravitational wave from a black hole binary has been observed for the first time. After this detection, it has been possible to investigate the nature of dynamical and strong regime of gravity. As of today, the number of gravitational waves detected is several tens, which enables us to test gravity statistically at high precision. In this project, I will construct an optimal framework to test gravity, including gravitational-wave generation, propagation, and detection, by statistically processing multiple gravitational wave signals.


I am very grateful to be selected for this prestigious research grant. This research was conceived more than three years ago, and I am thrilled to be able to start it now. I will continue to work hard to produce results and send them out to the world.
