Research Field

  • Gravitational-wave Astronomy

Brief Introduction of Research

  • Gravitational waves are patterns of spacetime strain propagating like ripples at the speed of light. The waves are quite faint, but human beings have succeeded the direct detections of them coming from astronomical objects. There are active studies to create a new frontier of astronomy with such gravitational waves that will continue to be observed. We are working for this theme from the experimental viewpoint including the improvement of the sensitivities of gravitational-wave telescopes, the detection principles, and the observational methods.
