Description

High-energy neutrinos could be produced in the interaction of charged cosmic rays with matter or radiation surrounding astrophysical sources. Transient phenomena, such as gamma-ray bursts, core-collapse supernovae or active galactic nuclei are promising candidates to emit high-energy neutrinos. To search for coincidences between a transient event and a neutrino emission, a follow-up program of neutrino alerts has operated within the ANTARES Collaboration since 2009. This program triggers a network of robotic optical telescopes immediately after the detection of a neutrino event and schedules several observations in the following weeks. The most interesting neutrino candidates are also followed by the Swift XRT telescope and the Murchison Wide field Array (MWA) radio telescope and the H.E.S.S. high-energy gamma-ray telescope. By combining the information provided by the ANTARES neutrino telescope with information coming from other observatories, the probability of detecting a source is enhanced, allowing the possibility of identifying a neutrino progenitor from a single detected event. No optical counterpart associated with a neutrino emission has been identified during image analysis.
