Abstract
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.
