Ten years of multi-wavelength follow-up observations of ANTARES neutrino alerts

摘要

High-energy neutrinos could be produced in the interaction of charged cosmic rays with matter or radiation surrounding astrophysical sources. To look for transient sources associated with a neutrino emission, a follow-up program of neutrino alerts is operating within the ANTARES Collaboration since 2009. This program triggers robotic optical telescopes (MASTER, TAROT, ROTSE, ZADKO and the SVOM ground based telescopes) immediately after the detection of each relevant neutrino candidate and schedule several observations in the following weeks. The most interesting neutrino candidates are also followed by the Swift and the INTEGRAL satellites, the Murchison Wide field Array radio telescope and the H.E.S.S. high-energy gamma-ray telescope. The results of ten years of observations are reported. No optical counterpart associated with a neutrino emission has been identified by ANTARES during image analysis and constrains on transient neutrino emission have been set.
