  1. Showering Neutrino Astronomies at Horizons Astronomia con i neutrini

  2. Update article Astronomia con i neutrini

  3. Why Neutrino may see where and what gamma and UHECR are no allowed to accelerated protons interact: => the energy fluences in -rays and neutrinos are comparable due to isospin symmetry. For neutrinos the observable spectrum is practically identical to the production spectrum, whereas -rays pile up below the pair production threshold on the CMB at a few 1014 eV. The Universe acts as a calorimeter for the total injected electromagnetic energy above the pair threshold. This constrains gamma but only part of the neutrino fluxes. Astronomia con i neutrini

  4. High Energy Neutrino Astronomyare a Must just behind the corner • Solar,Supernovae Neutrino Astronomy are probed. • Cosmic rays flux as rich as BBR, being charged, are bent and smeared, blinding most CR astronomy. • UHECR are direct, but BBR cut them, GZK cut , locally. • UHECR themselves must produce GZK- EeV neutrinos. • AGN, GRBs, Star Burst Galaxy must also produce PeV neutrinos. • UHE neutrinos must emerge above atmospheric neutrino noises: muons tracks and tau showers by their decay in flight (double bang) are their best trace.

  6. Local number flux of particles Astronomia con i neutrini

  7. Why Horizontal – Upward Tau air-showers are easier to be revealed than muon tracks ? Because an air- shower is amplified By its huge secondary number. Millions muons, billions gamma and e-pairs, trillions or more Cerenkov photons. Muon is single, alone and shine little. Astronomia con i neutrini

  8. Why Horizontal – Upward Tau Showering is so much linked to neutrino mass and mixing ? Because mixing, even for minimal masses guarantee the flavour transformation from Muon Neutrinos to the Tau Neutrinos. Galactic and cosmic distances are huge respect oscillation lenghts. 8.3pc Astronomia con i neutrini
