Observation of the highest energy cosmic rays by the Pierre Auger Observatory
Tuesday, 4. March, 11:00 h, KGII-Audimax
The Pierre Auger Observatory was designed to search for the sources of the highest energy cosmic rays. The Observatory, located in Argentina, is a hybrid detector which detects the cosmic rays by the shower particles arriving on the ground and the fluorescence produced by the shower particles passing through the atmosphere. It consists of 1600 particle detectors covering 3000km2 overlooked by four fluorescence detectors. The properties of the Observatory will be described. The measurement of the energy spectrum above 1018.5eV will be presented. The anisotropy will be shown as well as the observed correlation with nearby AGN’s.
