The observations of gravitational wave provide us the new possibility to approach the fundamental physics. Our group have studied the gravitational science in LIGO. We have played a role for calibration and coating studies. We will start the next observing run from 2022 Dec. Recently, we are also focusing on the development of new gravitational wave technology. To establish these technologies, the construction of the Academia Sinica Gravitational physics research facility (ASGRAF) was started from last year. In this facility, we will operate the interferometer system with cryogenic technology. In this talk, we will discuss the activity of LIGO and progress of R&D with new facility.
