ANTARES : Un observatoire du fond de la mer aux confins de l’Univers

Abstract : Neutrino astronomy is a new and unique method to explore the Universe. It is full of promises, such as improving our knowledge on cosmic accelerators or distinguishing unambiguously between hadronic and electronic acceleration mechanisms of very high energy cosmic rays. In this document the issues of neutrino astronomy are introduced and an overview of current and former neutrino telescopes is given, with a description of the performance results expected from the ANTARES underwater detector. My research path is marked by contributions to the detector calibration and by studies of the trigger system with the development of a new data selection algorithm. The potential for discovery of the ANTARES telescope is then illustrated with two analyses, one dedicated to the research of high-energy neutrinos from gamma ray bursters and the other dedicated to the search for magnetic monopoles. Within this dissertation, I also discuss the opportunity offered by a submarine detector to understand the deep-sea environment. Indeed, ANTARES is a multidisciplinary, permanent marine observatory bringing its brick to the edifice of the global understanding of physical phenomena and biological oceanography in the context of global changes. I illustrate these remarks with studies on marine bioluminescence observed by ANTARES and its connection to the dense water formation originating from the Gulf of Lion.
