Searching for Muon Neutrinos from Regions of the Localization of Gravitational-Wave Events

Data from the Baksan Underground Scintillation Telescope were used to search for muon neutrinos and antineutrinos with energies above 1 GeV in coincidence with gravitational-wave events detected by the Advanced LIGO and Advanced Virgo observatories in three observing periods. Limits on the integral fluxes of muon neutrinos and antineutrinos from gravitational wave sources were obtained. A way of searching for neutrino events from LIGO/Virgo alerts is presented. An algorithm for data processing and finding coincidences between neutrino and gravitational-wave events in real time is described.
