Description
Since 2015, the LIGO and Virgo collaborations have detected gravitational waves (GWs) from almost one hundred coalescences of compact objects (black holes and neutron stars). No neutrino counterparts have yet been clearly associated with these objects, across all energies from MeV to PeV. Such observation would greatly help in understanding the connection between the dynamics of the progenitor and the properties of the relativistic outflow at the origin of non-thermal high-energy emission.
Searches have been performed using data from the ANTARES neutrino telescope and the latest catalogues covering LIGO-Virgo third observation run (O3). Neutrinos within $\pm 500$ s of the GW time and direction compatible with the GW skymap are selected. The final results will be presented, as well as the corresponding bounds on neutrino emission from the events in the GW catalogues, assuming either isotropic emission or the presence of a jet. The results of a population study focusing on binary black hole mergers will also be described.
