Title: Results of the Pierre Auger Observatory on High Energy Cosmic Rays
Abstract: The Pierre Auger Observatory is a hybrid detector comprising water tank detectors covering an area of 3000 km2 and fluorescence detectors located in 4 stations surrounding that area. The Pierre Auger Observatory has been in operation for the past few years while its components were being gradually assembled and deployed on the field. In spite of the limited acceptance the data which have been gathered have already delivered interesting results on High Energy Cosmic Rays. This paper reviews the most interesting results published by our collaboration so far, including limits on high energy photons and neutrino fluxes, the spectrum, the anisotropy of Ultra High Energy Cosmic Rays and their correlation with extragalactic objects.
