Search for Neutrinos in Super-Kamiokande associated with Gravitational Wave Events GW150914 and GW151226

Understand

We report the results from a search in Super-Kamiokande for neutrino signals coincident with the first detected gravitational wave events, GW150914 and GW151226, using a neutrino energy range from 3.5 MeV to 100 PeV.

• We searched for coincident neutrino events within a time window of $\pm$500 seconds around the gravitational wave detection time.
• Four neutrino candidates are found for GW150914 and no candidates are found for GW151226.
• The remaining neutrino candidates are consistent with the expected background events.
