Abstract: We present the results of a blind search for overdensities with respect to isotropic expectations in the cosmic ray flux detected by the Pierre Auger Observatory. We analyze maps of significances in different energy ranges and for various angular scales. We have also searched for correlations of cosmic ray arrival directions with some promising candidate sources: the directions close to the Galactic Plane and the Galactic Center itself, in the perspective of a galactic origin of cosmic rays, and the Super-Galactic Plane and Centaurus A, in the perspectiveof an extra-galactic origin.
