Search for intrinsic anisotropy in the UHECRs data from the Pierre Auger Observatory
THE PIERRE AUGER COLLABORATION (AUTOR 434 DE 474); M. TUEROS
Conferencia; 31st International Cosmic Ray Conference; 2009
We discuss techniques which have been developed for determining the intrinsic anisotropy of sparse ultra-high-energy cosmic ray datasets, including a two point, an improved two point and a three point method. Monte-Carlo studies of the sensitivities of these tests are presented. We perform a scan in energy above the 100 highest energy events (corresponding to 43 EeV) detected at the Pierre Auger Observatory and find that the largest deviation from isotropic expectations occurs for events above 52 EeV.
