Abstract

In this proceedings we report on the status of searches for diffuse fluxes of cosmic neutrinos with the ANTARES neutrino telescope data. A complete overview of diffuse neutrino searches will be given, together with the search for a neutrino emission from regions such as the Fermi Bubbles or the Galactic Plane. A non-significant, though intriguing, excess of events above the atmospheric background is observed in all-sky analysis both for the track and shower channels.

Summary

Introduction

Cosmic Rays (CR) produced at astrophysical objects such as Supernova Remnants, Active Galactic Nuclei or Gamma Ray Bursts can interact in the interstellar medium and produce neutrinos. The ANTARES detector [1] is at present the largest neutrino telescope in the Northern Hemisphere, located at a depth of 2475 m in the Mediterranean Sea, 40 km off-shore Toulon, France and has been continuously operated since 2007. It consists of 885 photomultiplier tubes (PMTs), distributed along 12 mooring lines anchored to the sea bed and kept taut by top buoys. The IceCube Collaboration has reported [5] the observation of an all-flavour diffuse and isotropic excess of high energy neutrinos, not compatible with atmospheric expectations. The good agreement between data and Monte Carlo allowed for a final cut choice based on simulations
