UHECR narrow clustering correlating IceCube through-going muons

Abstract

The recent UHECR events by AUGER and the Telescope Array (TA) suggested that wide clusterings as the North and South, named Hot Spot, are related to near AGNs such as the one in M82 and Cen A (as most authors and us convened). In the same frame since 2008 we assumed that the UHECR are made by light and lightest nuclei to explain the otherwise embarrassing absence of the huge nearby Virgo cluster, absence due to the fragility and the opacity of lightest nuclei by photo-dissociation from Virgo distances. Moreover UHECR map exhibits a few narrow clustering, some near the galactic plane, as toward SS 433 and on the opposite side of the plane at celestial horizons: we tagged them in 2014 suggesting possible near source active also as a UHE neutrino. Indeed since last year, 2015, highest IceCube trough-going muons, UHE up-going neutrino events at hundreds TeV energy, did show (by two cases over three tagged in North sky) the expected overlapping of UHE neutrinos signals with narrow crowding UHECR. New recent data with higher energy threshold somehow re-confirmed our preliminary proposal offering also new possible sources by a additional correlated UHE-neutrino versus UHE-neutrino and-or with narro

Where are the Ultra High Energy Cosmic Ray (UHECR) originated?

“…In the same section we also discuss the case of an unexplained clustering correlated to a half cosmic radius 1 far source: 3C454. We proposed [9] and confirm here that this clustering, if growing (as it is) and being confirmed, might be associated and originated by a far beamed AGN, whose ZeV neutrino are scattering onto a relic cosmic neutrino background (with 1 − 2eV mass) via Z boson resonance (the so called Z burst model) [10][11][12][13]. Indeed the UHE ZeV neutrinos, emitted by far AGN do not interact with the cosmic photons and do not suffer of a GZK cutoff.…”

“…Finally a main cornerstone for an exciting new physics might be linked with the 3C 454 AGN clustering of UHECR events (see Fig.7 in this paper and also Fig. 5, arrow A in [13]). Also Mrk 421 and PKS 0208-512 may play such a role in additional two hot spots.…”

“…A ZeV UHE neutrino does scatter well with relic neutrinos in Z boson resonant peaked cross section [10]. The UHE Z boson decay in pions, nucleons and anti nucleons might be the observed UHECR and its hard gamma brightening [12,13]. These relic neutrinos with a mass in a cosmic presence of a relic hot universe, might be also tuned with the exciting (but still controversial) sterile neutrino existence (claimed with a mass well tuned at 1.6 eV).…”

A charming IceCube discover?

“…The poor shower (or cascade) directionality has been forcing us toward a more meaningful astronomy, even made mainly by through-going or crossing induced neutrino muons [4]. Within first several dozens of highest energy ICECUBE events we searched a signal correlation among these sources, [5,6]. More recent analogous attempts have been considered [7].…”
