Sidereal anisotropy of galactic cosmic ray observed by the tibet air shower experiment and the IceCube experiment

Abstract:

We analyze for the first time the large-scale sidereal anisotropy of -10 TeV cosmic ray intensity observed in two hemispheres, by best fitting a model to the anisotropies observed with the Tibet AS array in the northern hemisphere and the IceCube in the southern hemisphere. We find that the first and second harmonics of the right ascension distribution observed in two hemispheres are consistent with each other and well reproduced by a model of the superposed uni-directional and bi-directional cosmic ray flows. It is also shown that the best-fit amplitude and orientation of each flow are consistent with the best-fit parameters reported so far by the Tibet AS experiment.
