Abstract: The Telescope Array experiment has collected 5 years of data and accumulated the largest to date UHECR data set in the Northern hemisphere. We make use of this data set to search for large- and small-scale anisotropy of UHECR. We begin by testing the previously existing claims of anisotropy at highest energies, namely, the clustering at small scales and correlations with the nearby AGNs. We then extend the search by including other classes of extragalactic objects – putative sources of UHECR. Finally, we cross-correlate the UHECR events with the large-scale structure of the Universe. We also present the results of the search for point-like sources of neutral particles and for a large-scale anisotropy at energies around 1 EeV. While low-energy sets are compatible with isotropy, the highest-energy set with E> 57 EeV shows deviations from isotropy in most of the tests at 2−3σ C.L. (pre-trial)
