Description
Since the first direct observation of gravitational waves in September 2015, gravitational waves generated by binary black hole mergers and binary neutron star mergers have already been observed about 90 times. In particular, the binary neutron star merger in August 2017 was an extremely impactful astronomical phenomenon, as not only gravitational waves but also gamma-ray bursts were observed almost simultaneously and were also observed by astronomical instruments at all wavelengths based on sky-location information from the gravitational wave observation.
Currently, there are two LIGO detectors in US, Virgo in Europe, and KAGRA in Japan. These detectors are planning to perform the next observing run which starts in the spring of 2023, and more gravitational signals are expected to be observed. KAGRA is preparing to contribute to gravitational wave astronomy in the coming observating runs.
In this talk, I will discuss the observation of gravitational waves from coalescing compact binaries so far, the status of the KAGRA detectors, and the future prospects for gravitational wave observations.
