Brief Introduction of Research
- The emission of gravitational waves, distortion of the space-time structure propagating at the speed of light, by accelerating masses was predicted by Albert Einstein from his theory of general relativity more than 90 years ago. Since then, the direct detection of gravitational waves has been the holy grail for the test of the general relativity under strong gravity field. Moreover, the observations of gravitational waves from astronomical sources will provide us with rich and unique opportunities to explore the physics of extreme conditions, such as the equation of state of neutron stars, the direct measurement of black hole parameters, the explosion mechanism of supernovae etc. I am currently involved in the development of the KAGRA gravitational wave detector in Japan. I am also applying precision measurement techniques of the GW detectors to other fields such as atomic clocks and quantum measurements.
