Abstract
Operating 40 km off the coast of France since 2007, the ANTARES detector is the largest deep-sea neutrino telescope in the Northern Hemisphere with an instrumented volume of more than 0.01 cubic kilometers. It consists of an array of 885 photomultipliers detecting the Cherenkov light induced by charged leptons produced by neutrino interactions in and around the detector. The primary goal of ANTARES is to search for astrophysical neutrinos in the TeV–PeV range. This comprises generic searches for any diffuse cosmic neutrino flux as well as more specific searches for astrophysical galactic and extragalactic sources. The search program also includes multi-messenger analyses based on time and/or space coincidences with other cosmic probes. The ANTARES observatory is sensitive to a wide-range of other phenomena, from atmospheric neutrino oscillations to dark matter annihilation. In this contribution, recent results from the ANTARES neutrino telescope will be presented.
Highlights
After almost 50 years since the first proposal of exploiting deep-sea waters to detect cosmic high-energy neutrinos we are at the verge of opening a neutrino era in high-energy astrophysics thanks to the results of the IceCube neutrino telescope in Antarctica that show mounting evidence of a flux of neutrinos in the 10 TeV – 1 PeV range exceeding the known flux of atmospheric neutrinos by a statistically significant factor [1]
Some of these limits are relatively close to the expected fluxes, suggesting that at least part of the phase space for hadronic models of gamma-ray emission in the Fermi Bubbles (FBs) could be probed with the full ANTARES data set, or after about 1 year of operation of the next-generation KM3NeT neutrino telescope [26]
The ANTARES detector is currently the largest neutrino telescope that has ever operated in the Northern Hemisphere, and the first to be deployed in the deep sea
Summary
After almost 50 years since the first proposal of exploiting deep-sea waters to detect cosmic high-energy neutrinos we are at the verge of opening a neutrino era in high-energy astrophysics thanks to the results of the IceCube neutrino telescope in Antarctica that show mounting evidence of a flux of neutrinos in the 10 TeV – 1 PeV range exceeding the known flux of atmospheric neutrinos by a statistically significant factor [1]. The charged current interaction of a muon neutrino results in a muon that at an energy around 1 TeV has path lengths in water of the order of a few kilometers, providing a long lever arm for direction reconstruction. These track-like events are considered the golden channel for neutrino astronomy A search bin around the source position can be used
