earch for neutrinos from transient sources with the ANTARE telescope and optical follow-up observations (TAToO)

摘要

The ANTARE telescope has the opportunity to detect transient neutrino sources, such as gamma-ray bursts, core-collapse supemovae, flares of active galactic nuclei. In order to enhance the sensitivity to these sources, we have developed a new detection method based on the follow-up by optical telescopes of "golden" neutrino events, such as neutrino doublets coincident in time and space or single neutrinos of very high energy. The ANTARE collaboration has therefore implemented a very fast on-line reconstruction with a good angular resolution. These characteristics allow us to trigger an optical telescope network. ince February 2009, ANTARE is sending alert triggers once or twice per month to the two 25 cm robotic telescope of TAROT. This optical follow-up of such special events would not only give access to the nature of the sources, but also would improve the sensitivity to transient neutrino sources.
