The Pierre Auger Observatory: Results on Ultra-High Energy Cosmic Rays
arXiv:0807.4871 · doi:10.1143/JPSJS.78SA.114
Abstract
The focus of this article is on recent results on ultra-high energy cosmic rays obtained with the Pierre Auger Observatory. The world's largest instrument of this type and its performance are described. The observations presented here include the energy spectrum, the primary particle composition, limits on the fluxes of photons and neutrinos and a discussion of the anisotropic distribution of the arrival directions of the most energetic particles. Finally, plans for the construction of a Northern Auger Observatory in Colorado, USA, are discussed.
