Real-time follow-up of multi-messenger alerts with the ANTARES neutrino telescope
Résumé
By constantly monitoring at least one complete hemisphere of the sky, neutrino telescopes are
well designed to detect neutrinos emitted by transient astrophysical events. Real-time searches
for neutrino candidates coincident with Swift and Fermi gamma-ray bursts, IceCube high energy
neutrino events and gravitational wave (GW) candidates observed by LIGO/Virgo are performed
with the ANTARES telescope. By requiring temporal coincidence, this approach increases the
sensitivity and the significance of a potential discovery. The latest results of these analyses will
be presented, with emphasis on the results of the neutrino follow-up of IceCube very high-energy
neutrino events and LIGO/Virgo GW public events during the run O3. In case of a coincident detection, the position of the GW source on the sky would be largely constrained thanks to the better
angular accuracy of ANTARES compared to the GW detectors, bringing valuable information for
subsequent electromagnetic follow-ups. In case of no coincidence, an upper limit on the neutrino
fluence and the total energy emitted in neutrinos will be provided for each studied alert.
