[CRI272] Arrival directions of the highest-energy cosmic rays detected by the Pierre Auger Observatory



Primary authors


The Pierre Auger Observatory located near the town of Malargüe (Argentina) is the largest facility for studying cosmic rays above 10^17 eV. The searches for anisotropies in the arrival direction distribution carry important information on the sources distribution and on the propagation of cosmic rays. We update the results of the searches for anisotropies in the distribution of arrival directions of cosmic rays detected above 4 × 10^19 eV at the Pierre Auger Observatory. We report the searches for self-clustering of event directions at small and intermediate angular scales and at different energy thresholds. We examine the correlation with celestial structures in the Galaxy (Galactic Center and Galactic Plane) and in the local universe (the Super Galactic Plane). We also compare the distribution of arrival directions with that of different populations of relatively nearby extragalactic objects and with Centaurus A.
