Observation of the Moon shadow with the ANTARES neutrino telescope
Résumé
ANTARES is currently the largest neutrino telescope on the Northern Hemisphere. It consists of a three-dimensional array of PMTs deployed at a depth of 2475 m off-shore the Toulon cost in France. Operating since May 2008 in its full configuration, it aims to detect high-energy cosmic neutrinos. In the absence of an astrophysical standard cand le, a possible way to measure the angular resolution and the pointing accuracy for a neutrino telescope is to look at "Moon shadow" in the atmospheric muon flux. The analysis method and the first results of the observation of the Moon shadow with ANTARES will be presented and discussed. The data, analysed in this work,were collected between Jan 31st, 2007 and Dec 31th 2010, for a total live time of 814 days.
