Description

This thesis is devoted to ANTARES, the first underwater neutrino telescope in the Mediterranean sea.�As the main scientific analysis, a search for high-energy neutrino emission from the region of the Fermi bubbles has been performed using data from the ANTARES detector. A method for the background estimation using off-zones has been developed specially for this measurement. A new likelihood for the limits calculation which treats both observations in the on-zone and in the off-zone in the similar way and also includes different systematic uncertainties has been constructed.�The analysis of 2008�2011 ANTARES data yielded a 1.2 ?� excess of events in the Fermi bubble regions, compatible with the no-signal hypothesis. For the optimistic case of no energy cutoff in the flux, the upper limit is within a factor of three of the prediction of the purely hadronic model based on the measured gamma-ray flux. The sensitivity improves as more data are accumulated (more than 65% gain in the sensitivity is expected once 2012�2016 data are added to the analysis).Typham this is the title: Neutrino Astrophysics with the ANTARES Telescope
