On the arrival directions of the highest energy cosmic rays detected by the Pierre Auger Observatory

We report different analyses of the arrival directions of the highest energy cosmic rays detected by the Pierre Auger Observatory between 1 January 2004 and 31 December 2009. We update the measured fraction of arrival directions correlating with the positions of objects in the Véron-Cetty and Véron (VCV) catalog. We examine the arrival directions in relation to other populations of nearby extragalactic objects: galaxies in the 2 Microns All Sky Survey and active galactic nuclei in the Swift-BAT hard X-ray catalog. We also show the 2-point autocorrelation function and analyse the sky region with the largest excess compared to isotropic expectations.
