Tau Airshower Astronomy in space
Session and Location
Wednesday Session, Poster Wall #171 (Ballroom)
The Ultra High Energy neutrino astronomy at PeV has been partially opened by Icecube few events. The several abundant tens or hundred TeVs neutrino might be polluted by common or prompt charmed atmospheric neutrino. Indeed the absence of any galactic plane clustering, the paucity or absence of AGN or GRB gamma correlated neutrino events, as well as the absence of any gamma or X signal along highest muon neutrino tracks, all point to a possible noisy atmospheric neutrino smeared sky. Indeed the persistent absence of a double bang signal within a dozen or more hundred TeV Icecube events suggest still an atmospheric polluted neutrino record. However PeVs up to EeVs tau neutrino well expected by astrophysical mixed far sorces, but totally absent via short terrestrial oscillations, they may hit Earth crust , produce long life penetrating tau, leading to final horizontal or upgoing tau airshowers. Their airshower existence has been foreseen 20 years ago, on Earth and Space , now.
