Upper limit on the primary photon fraction from the Pierre Auger Observatory | The Pierre Auger Collaboration
; | Date: |
18 Jul 2005 | Subject: | astro-ph | Abstract: | Based on observations of the depth of shower maximum performed with the hybrid detector of the Auger Observatory, an upper limit on the cosmic-ray photon fraction of 26% (at 95% confidence level) is derived for primary energies above 10^19 eV. Additional observables recorded with the surface detector array, available for a sub-set of the data sample, support the conclusion that a photon origin of the observed events is not favoured. | Source: | arXiv, astro-ph/0507402 | Services: | Forum | Review | PDF | Favorites |
