Description
abstract: We will start by reviewing the searches for anisotropy of the ultra-high energy cosmic rays in the Telescope Arrray. With the exception of the "hot spot" in the highest energy region which still needs to be confirmed, no anisotropy is found. We will then address a question whether this is compatible, at the quantitative level, with theoretical expectations given that at highest energies the UHECR propagation distance is limited by O(100) Mpc, while the sources should follow the matter distribution which is inhomogeneous at these scales.
