Energy-position correlation anisotropy of ultra-high energy cosmic rays with Telescope Array Data
Indication of an energy dependent intermediate-scale anisotropy has been found in the arrival directions of ultra-high energy cosmic rays with energies above 20 EeV in the northern hemisphere, using 7 years of TA surface detector data. The previously reported “hotspot“ excess for E>57 EeV is found to correspond to a deficit, or “coldspot“, of events for energies 20<E<57 EeV. At the center of maximum combined significance the excess for energies E>57 EeV has a Li-Ma statistical significance of 4.62σ, and the deficit for energies 20<E<57 EeV a significance of -3.23σ. This combined feature is centered at R.A. = 146◦, decl. = 47◦(3◦ degrees from previously reported hotspot) and is 17◦ from the supergalactic
plane. The hot/coldspot feature suggests energy dependent magnetic deflection of the isotropic background and cosmic-rays from a source.
