IceCube search for neutrino-induced muons from gravitational wave sources

IceCube has searched for high-energy neutrinos associated with gravitational wave sources during LIGO/Virgo/KAGRA runs O1, O2, and O3. The analyses have occurred both in real time, reporting results typically within an hour of gravitational wave arrival at Earth, and on refined archival catalogs of gravitational wave events. IceCube localizes the neutrinos that produce muons to a sky area several hundred times smaller than typical gravitational wave localizations. Because of this, reporting results in real time can enable other telescopes to search a much smaller area for counterparts. We report results from searches through O3 as well as the status of real-time analysis during run O4.
