This event has already occurred. The information may no longer be valid.

The Department of Physics welcomes Dr. Kokeyama from the KAGRA Observatory, ICRR, University of Tokyo, to deliver a presentation as part of the Spring 2020 colloquia.

Multimessenger observation with gravitational wave telescopes and many other kinds of telescopes has begun since the first binary neutron star merger detected on August 17th, 2017. LIGO and VIRGOgravitational wave detectors have been in their third observation run (O3)  since the spring of 2019, and many more discoveries are expected in this one year observation.

KAGRA is an underground and cryogenic gravitational-wave telescope, placed in Kamioka, Gifu, Japan, where is known as a mecca of underground experiments of physics (i.e., Super Kamiokande for Neutrino detections). The excavation of the underground tunnel has finished in 2014, and the installation of instruments has finished in the later 2018. Currently, the detector commissioning to attain an astrophysical sensitivity is intensively ongoing, aiming to start the observation as soon as possible.

In this talk, gravitational-wave astrophysics by LIGO and VIRGO will be reviewed, as well as the status and prospects of the KAGRA detector will be presented.
