Plot showing the typical sensitivity of KAGRA (yellow) and GEO (black) during the joint observing period. The vertical axis gives the average strain noise in the detectors, which is a measure of how much the mirrors typically move as a function of frequency (horizontal axis). The solid curves show the mean sensitivity for each frequency bin and the shaded regions show the 5th and 95th percentile over the period.

In a new paper submitted to the arXiv, the LIGO-Virgo-KAGRA Collaborations have reported the results of the first joint observation of the KAGRA detector in Japan with GEO600. The two-week observing run took place in April 2020. The analysis involved searching for multiple types of gravitational-wave signals, including all-sky searches for binary neutron star coalescences and targeted searches for signals associated with gamma-ray bursts reported during the observing run. Although no gravitational-wave signals were identified, these searches demonstrate the feasibility and utility of KAGRA as a member of the global gravitational-wave detector network.
