“…During the third observing run, LIGO-O3, the LIGO/Virgo collaboration initiated the online GW candidate event database (GraceDB) (LIGO Scientific Collaboration 2020), providing public alerts and a centralized location for aggregating and retrieving event information. For such transient GW events, various neutrino detectors reported correlation searches: Super-Kamiokande (Abe et al 2016(Abe et al , 2018, Borexino (Agostini et al 2017), NOvA (Acero et al 2020), Bikal-GVD Neutrino Telescope (Avrorin et al 2018), Daya Bay (An et al 2020), XMASS (Collaboration et al 2020), and IceCube/ANTARES (Adrián-Martínez et al 2016;Albert et al 2017b;Aartsen et al 2020). The Kamioka Liquid scintillator AntiNeutrino Detector (KamLAND) has also performed a search for electron antineutrinos coincident with gravitational waves GW150914 and GW151226, and then candidate event LVT151012 (Gando et al 2016a).…”
