I performed my PhD Thesis inside the ANTARES telescope collaboration. This telescope allows magnifying our vision of the Universe through the neutrinos. Now, it's arrived at the end of the deployment and connection period of each detection line in the Mediterranean Sea at ~2500m in depth. It comprises an array of 900 photomultipliers (12 lines) that are sensitive to the Cherenkov light emitted by high-energy muons, resulting from the interaction of a neutrino close to the detector. My PhD thesis consisted in calibration of the detector, in time and charge, before the deployment to extract the crucial data for the reconstruction and tracks identifications (Astrophysical neutrinos or atmospherics neutrinos/muons). Among this, the indirect search of Dark Matter is possible, and I focused my work onto the self-annihilations into the Sun.
