LIGO-VIRGO-KAGRA PUBLISH NEW RESULTS FROM THE O3 GEO-KAGRA OBSERVING RUN

3 Mar 2022 — 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 the UK-German interferometer GEO600, located near Hannover. The two-week observing run took place in April 2020. Our analysis involved searching for multiple classes 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. The paper is available on arXiv.org, and a Science Summary is available here.
