Abstract
Ultra High Energy Cosmic Rays (UHECR), made mostly by Helike lightest nuclei might fit the observed spread clustering along Cen-A; He like UHECR nuclei explain also Virgo absence because these light nuclei fragility and opacity above a few Mpc. UHECR He from Cen-A AGN being fragile should partially fragment into secondaries at tens EeV multiplet (D, 3He, p) as it appears in a twin multiplet discovered (AUGER-ICRC-2011), at 20 EeV along the same Cen-A UHECR clustering. We suggest that UHECR are also (possibly mostly) heavy radioactive galactic nuclei as 56Ni, 57Ni and 57Co, 60Co widely bent (tens degree up to ≥ 100◦) by galactic fields. UHECR radioactivity (in β and γ channels) and decay in flight at hundreds keV is boosted (by huge Lorentz factor ΓNi 109–108) leading to PeVs electrons and consequent synchrotron TeVs gamma offering UHECR-TeV correlated wide area sky anisotropy. Additional electron and tau neutrinos secondaries at PeVs might be the first signature of such expected radioactive secondary tail. Being smeared such decayed neutrinos will be hardly clustered in small scale.
