Description
The ANTARES telescope is well suited to detect neutrinos produced in astrophysical transient
sources as it can observe a full hemisphere of the sky with a high duty cycle. Potential
neutrino sources are gamma-ray bursts, core-collapse supernovae and flaring active galactic
nuclei. To enhance the sensitivity of ANTARES to such sources, a detection method based on
follow-up observations from the neutrino direction has been developed. This program,
denoted as TAToO, includes a network of robotic optical telescopes (TAROT, Zadko and
MASTER) and the Swift-XRT telescope which are triggered when an “interesting” neutrino is
detected by ANTARES.
A follow-up of special events, such as neutrino doublets in time/space coincidence or single
neutrino having a very high energy or in the specific directions of local galaxies, significantly
improves the perspective for the detection of transient sources. As images can be taken
within 20 seconds after the neutrino trigger and as observations are also made up to two
months after the alert, the search for fast transient sources such as gamma-ray burst
afterglows or slowly rising sources such as core-collapse supernovae becomes possible.
Recently, the follow-up has been extended with a search for correlations between neutrinos
and individual high energy photons detected by Fermi-LAT.
The analysis of follow-up observations, as well as the search for ν/γ correlations have been
done and the results covering optical, X-ray and gamma-ray data, will be presented.
