WebbCLIO: Prototype Cryogenic Detector. Since KAGRA will be the first large interferometer gravitational wave detector with cryogenic mirrors, it was necessary to demonstrate … Webb19 feb. 2024 · We propose a novel mechanism to test time variation of the propagation speed of gravitational waves (GWs) in light of GWs astronomy. As the stochastic GWs experience the whole history of cosmic expansion, they encode potential observational evidence of such variation. We report that, one feature of a varying GWs speed is that …

The Kamioka Gravitational Wave Detector (KAGRA), is a large interferometer designed to detect gravitational waves predicted by the general theory of relativity. KAGRA is a Michelson interferometer that is isolated from external disturbances: its mirrors and instrumentation are suspended and … Visa mer It was formerly known as the Large Scale Cryogenic Gravitational Wave Telescope (LCGT). The ICRR was established in 1976 for cosmic ray studies. The LCGT project was approved on 22 June 2010. In January 2012, it … Visa mer Two prototype detectors were constructed to develop the technologies needed for KAGRA.
