Searches for IceCube Neutrinos Coincident with Gravitational Wave Events

Understand

Searches for neutrinos from gravitational wave events have been performed utilizing the wide energy range of the IceCube Neutrino Observatory.

• We discuss results from these searches during the third observing run (O3) of the advanced LIGO and Virgo detectors, including a low-latency follow-up of public candidate alert events in O3, an archival search on high-energy track data, and a low-energy search employing IceCube-DeepCore.
• The dataset of high-energy tracks is mainly sensitive to muon neutrinos, while the low energy dataset is sensitive to neutrinos of all flavors.
• In all of these searches, we present upper limits on the neutrino flux and isotropic equivalent energy emitted in neutrinos.
