Ultrahigh energy neutrinos scattering off relic light neutrinos to explain UHECR above GZK cut off and thin blazars
Daniele Fargion, Barbara Mele
UHE neutrinos may transfer highest cosmic-rays energies overcoming BBR and radio-waves opacities (the GZK cut off) from most distant AGN sources at the age of the Uni…

Scattering of Ultrahigh Energy (UHE) Extragalactic Neutrinos onto Light Relic Neutrinos in Galactic HDM Halo Overcoming the GZK Cut off
D. Fargion, B. Mele
The rarest cosmic rays above the GZK cut'off are probably born at cosmic distances ( tens Mpc) by AGNs (QSRs, BLac, Blazars...).…
