Resumen:
A thorough search of the sky exposed at the Pierre Auger Cosmic Ray Observatory reveals no statistically significantexcess of events in any small solid angle that would be indicative of a flux of neutral particles from a discrete source.The search covers from −90◦ to +15◦ in declination using four different energy ranges above 1 EeV (1018 eV).The method used in this search is more sensitive to neutrons than to photons. The upper limit on a neutron flux isderived for a dense grid of directions for each of the four energy ranges. These results constrain scenarios for theproduction of ultrahigh energy cosmic rays in the Galaxy.
