High-energy neutrino follow-up search of gravitational wave event GW150914 with ANTARES and IceCube

Four collaborations, ANTARES, IceCube, LIGO, and Virgo, join forces to report the non-observation of neutrino events correlated with the GW150914 gravitational wave event reported recently by LIGO. Although the paper reports a negative result, it both sets important constraints on neutrino production in binary coalescence events and marks a significant step in multimessenger astronomy.
