High-Energy Neutrino follow-up of the first neutron star/neutron star gravitational-wave event GW170817 |
|
Abstract |
For the first time, on August 17th 2017, the LIGO/Virgo interferometers have detected the coalescence of two neutron stars whose associated electromagnetic emission has been observed from radio to gamma-rays. A neutrino follow-up was performed using ANTARES data to search for a potential high-energy neutrino counterpart to this event, together with IceCube and the Pierre Auger Observatory, to cover the GeV-EeV energy range. No neutrino candidate in both temporal and spatial coincidence with GW170817 had been detected within +/-500 s from the event and over an extended time window of +14 days. The neutrino fluence was constrained and compared with theoretical models. These results will be presented, together with searches dedicated to black-black hole binaries detected by LIGO/Virgo during earlier observation runs. |
