The Advanced LIGO and Advanced Virgo observatories recently discovered gravitational waves from a binaryneutron star inspiral. A short gamma-ray burst (GRB) that followed the merger of this binary was also recorded bythe Fermi Gamma-ray Burst Monitor (Fermi-GBM), and the Anti-Coincidence Shield for the Spectrometer for theInternational Gamma-Ray Astrophysics Laboratory (INTEGRAL), indicating particle acceleration by the source.The precise location of the event was determined by optical detections of emission following the merger. Wesearched for high-energy neutrinos from the merger in the GeV?EeV energy range using the ANTARES, IceCube,and Pierre Auger Observatories. No neutrinos directionally coincident with the source were detected within ±500 saround the merger time. Additionally, no MeV neutrino burst signal was detected coincident with the merger. Wefurther carried out an extended search in the direction of the source for high-energy neutrinos within the 14 dayperiod following the merger, but found no evidence of emission. We used these results to probe dissipationmechanisms in relativistic outflows driven by the binary neutron star merger. The non-detection is consistent withmodel predictions of short GRBs observed at a large off-axis angle.
