Search for localized excess fluxes in Auger sky maps and prescription results

Abstract

Using the first surface detector data of the Pierre Auger Observatory, we present the results of a blind search for overdensities in the cosmic ray flux with respect to isotropic expectations. We consider two energy bands: 1<E<5 EeV and E>5 EeV at two angular scales: 5$^\circ$ and 15$^\circ$. We also report the results of searches for excesses in target directions already defined in a set of prescriptions presented at the ICRC in 2003. Both analyses give results that are compatible with isotropy.
