Where are UHECR originated ? [HEAP]

http://arxiv.org/abs/1805.01572


Recent and abundant (2013-2015) UHECR air-shower shape detections, by AUGER and TA, their air-shower slant depth records, finally convinced that the UHECR are mostly lightest nuclei. The rich unexpected anisotropy (7%) of ten EeV UHECR have shown (2017) a remarkable (5 sigma) signal showing an unexpected UHECR dipole anisotropy . This year, an updated 39 EeV and 60 EeV UHECR event maps by AUGER (2018), are showing enhanced clustering on nearest localized AGN or star-burst sources in the local universe, as have been suggested earlier (2008-2015). We show the chain of argument that led us to identify first extragalactic Cen A, M82, NGC 253 and Fornax D as the main nearby sources. We explain as the dipole anisotropy might finally find a main component (at 10 EeV UHECR) born within nearby galactic sources. We finally underline two uncorrelated clustering around 3C 454 and Markarian 421: we revive for them a ZeV (UHE) neutrino model (by cosmic far AGN) hitting onto a cosmic relic neutrino (with an eV mass, maybe sterile one) making a Z boson resonance overcoming the GZK cut off.
