The Advanced LIGO and Advanced Virgo observatories recently discoveredgravitational waves from a binary neutron star inspiral. A shortgamma-ray burst (GRB) that followed the merger of this binary was alsorecorded by the Fermi Gamma-ray Burst Monitor (Fermi-GBM), and theAnti-Coincidence Shield for the Spectrometer for the InternationalGamma-Ray Astrophysics Laboratory (INTEGRAL), indicating particleacceleration by the source. The precise location of the event wasdetermined by optical detections of emission following the merger. Wesearched for high-energy neutrinos from the merger in the GeV-EeVenergy range using the ANTARES, IceCube, and Pierre Auger Observatories.No neutrinos directionally coincident with the source were detectedwithin ±500 s around the merger time. Additionally, no MeVneutrino burst signal was detected coincident with the merger. Wefurther carried out an extended search in the direction of the sourcefor high-energy neutrinos within the 14 day period following the merger,but found no evidence of emission. We used these results to probedissipation mechanisms in relativistic outflows driven by the binaryneutron star merger. The non-detection is consistent with modelpredictions of short GRBs observed at a large off-axis angle.
