Search for Neutrinos in Super-Kamiokande Associated with Gravitational Wave Events

Abstract

We report the results from a search in Super-Kamiokande for neutrino signals coincident with gravitational-wave events using a neutrino energy range from 3.5 MeV–100 PeV. We searched for coincident neutrino events within a time window of ± 500 s around the gravitational-wave detection time. In this work, we report the number of events within the search-window and the 90 % confidence level upper limits on the neutrino fluence for each gravitational-wave event.
