KAGRA Gravitational-wave Telescope Begins Observations

On February 25, Kamioka Gravitational Wave Detector (KAGRA) started its 1st observing run.  

KAGRA is a large-scale cryogenic gravitational-wave telescope in Kamioka, Japan, managed by the Institute for Cosmic Ray Research (ICRR) of the University of Tokyo. It is the first gravitational-wave observatory in Asia; the first such observatory built underground; and the first whose detector uses cryogenic mirrors. On October 4, 2019, a Memorandum of Agreement was signed by KAGRA, LIGO, and Virgo about joining their collaborative efforts, including plans for future joint observations and data sharing.  

Congratulations to our KAGRA colleagues on this milestone!
