Astrophysical neutrinos may be produced during the coalescence of compact objects, in particular those involving neutron stars. Such mergers have been observed through gravitational wave detections by the LIGO-Virgo-KAGRA interferometers. The ANTARES and KM3NeT deep-sea neutrino telescopes are sensitive to neutrino interactions in a wide range of energies, from MeV to PeV. In this contribution, recent searches for correlation in time and space between neutrinos and gravitational wave signals are reviewed. In particular, the results of follow-ups with the KM3NeT real-time system for alerts from the fourth observing run of LIGO-Virgo-KAGRA will be reported for the first time. Additionally, prospects for future studies using archival data from both neutrino and gravitational wave detectors will be outlined.
Lamoureux et al. (2025) studied this question.
