TL;DR: In this article, the authors reported the observation of gravitational waves from two compact binary coalescences in LIGO's and Virgo's third observing run with properties consistent with neutron star-black hole (NSBH) binaries.

TL;DR: KAGRA as discussed by the authors is a 2.5-generation GW detector with two 3'km baseline arms arranged in an 'L' shape, similar to the second generations of Advanced LIGO and Advanced Virgo, but it will be operating at cryogenic temperatures with sapphire mirrors.

TL;DR: The Large-scale Cryogenic Gravitational wave Telescope (KAGRA) as discussed by the authors is a 2.5-generation GW detector with two 3-km baseline arms arranged in the shape of an "L", located inside the Mt. Ikenoyama, Kamioka, Gifu, Japan.

TL;DR: In this article, the authors report results of a search for an isotropic gravitational-wave background (GWB) using data from Advanced LIGO's and Advanced Virgo's third observing run (O3) combined with upper limits from the earlier O1 and O2 runs.

TL;DR: KAGRA as discussed by the authors is a newly built gravitational-wave telescope, a laser interferometer comprising arms with a length of 3 km, located in Kamioka, Gifu, Japan.
