IceCube search for neutrino-induced cascades from gravitational wave sources

Some models predict an associated neutrino signal from compact object mergers in addition to the observed gravitational waves. Previous searches have set upper limits on the neutrino flux from mergers, but no significant detection has been reported. The LIGO-Virgo Collaboration (LVC) has released archival data for 3 operating runs with 91 total events detected. A new IceCube Neutrino Observatory dataset has been developed with all-flavor cascade-type events with reduced angular uncertainty and improved sensitivity in the southern hemisphere. We discuss an ongoing neutrino-gravitational wave coincidence study using the improved IceCube dataset and archival data from past LVC runs.
