Search for neutrino counterparts of gravitational-wave events detected by LIGO and Virgo during run O2 with the ANTARES telescope

Understand

An offline search for a neutrino counterpart to gravitational-wave (GW) events detected during the second observation run (O2) of Advanced-LIGO and Advanced-Virgo performed with ANTARES data is presented.

• In addition to the search for long tracks induced by $\nu_\mu$ ($\bar{\nu}_{\mu}$) charged current interactions, a search for showering events induced by interactions of neutrinos of any flavour is conducted.
• The severe spatial and time coincidence provided by the gravitational-wave alert allows regions above the detector horizon to be probed, extending the ANTARES sensitivity over the entire sky.
• The results of this all-neutrino-flavour and all-sky time dependent analysis are presented.
