1 Ultra High Energy Cosmic Ray radioactivity in flight painting TeV anisotropy sky
D.Fargion; Rome Univ.1 and INFN , Rome , Italy Introduction; The presence of large scale TeVs anisotropy in Milagro, ARGO, ICECUBE and today Hawc sky remain a mistery: how may charged cosmic rays at tens TeV remain correlated while being bent by local solar and galactic magnetic fields in an expected smeared nearly homogeneous maps? Consider the Main CR anisotropy nearby Crab D.Fargion_CERN_

2 There are two main TeVs CR anisotropy in last Hawc Map: Region A and B, C

3 The previous ARGO multi-energy gamma-CR sky is somehow the most telling in this source search connection. D.Fargion_CERN_

4 The same image seen from an anticentric galactic coordinate
Map based on Crab. The role of the TeV anisotropy below (A) is well linked to the pulsar Crab in the ARGO center map D.Fargion_CERN_

5 Consider the zoomed region A at TeV anisotropy not far from Crab

6 Does the origin of the Milagro-ARGO-Hawc anisotropy A be the small square or the black (Crab) circle? Crab is the probable source D.Fargion_CERN_

7 How may tens TeV reach such kpc distances ?
We considered_2012_ UHECR as mostly light (or lightest ) radioactive nuclei whose decay in flight may feed by alfa and neutron as well as by gamma secondaries at the tens TeVs anisotropy. D.Fargion_CERN_

8 Addditional Taces We showed in the past the overlapping of UHECR and TeV sky, with remarkable correlation, whose presence might point for nearby galactic sources as Crab, Vela, Cygnus X3 and maybe nearest AGN as Cen A. D.Fargion_CERN_

9 More recent maps (2015) of UHECR and TeVs anisotropy

10 Conclusions UHECR by Light nuclei in flight and their decay may pollute by their (smeared) direction the tens TeV sky by He (alfa) and neutrons and gamma leading to present tiny large scale TeV anisotropy in sky. D.Fargion_CERN_
