【 摘 要 】

The ANTARES neutrino telescope is located in the Mediterranean Sea off the coast of France and offers a high visibility of the Galactic plane. Its main scientific goal is the detection of cosmic neutrinos, which is achieved by measuring the Cherenkov light emitted by the products of neutrino interactions. A limit on the all-sky diffuse neutrino flux has been set using muon-neutrinos, and a new analysis provides an improved sensitivity by also using showers created in electron- and tau-neutrino interactions. In addition, the high visibility of the Galactic plane is exploited in a dedicated analysis focussing on the Galactic plane. In this analysis the diffuse muon-neutrino flux of a region around the Galactic plane is compared with the flux from multiple equivalent off-source regions. Results of these analyses using five years of data will be reported.
