UHECR besides CenA: hints of galactic sources

Abstract

Ultra High Energy Cosmic Rays, UHECR, maybe protons, as most still believe and claim, or nuclei; in particular lightest nuclei as we advocated recently. The first (Auger Collaboration) nucleon proposal (2007)[2] foresaw to trace clearly the UHECR GZK Universe reaching far (up to 100 Mpc) Super-Galactic-Plane, with little angular dispersion. On the contrary Lightest Nuclei model (2008)[3], inspired by observed composition and by nearest CenA clustering (almost a quarter of the AUGER events) explains a modest and narrow (few Mpc) Universe view, as well as the puzzling Virgo absence: lightest nuclei offer a fragile (and therefore very nearby) blurred Astronomy. Here we address to a part of the remaining scattered events in the new up-dated Auger map (March 2009-ICRC09). We found within rarest clustering the surprising imprint of a few galactic sources, a partial component of UHECR sources. In particular we recognize a first trace of Vela, brightest gamma and radio galactic source, and smeared sources along Galactic Plane and Center. The clustering may imply additional tails of fragments (by nuclei photo-dissociation) at half energies. The UHECR light-nuclei fragility and opacity may also reflect into a train of secondaries as gamma and neutrinos UHE events at tens-hundred PeVs. These UHE neutrinos might be detectable in a coming future within nearest AUGER and Array Fluorescence Telescope views,(few km distances) by fast fluorescence flashing of horizontal up-going tau Air-showers.
