Resumen:
A thorough search of the sky exposed at the Pierre Auger Cosmic Ray
Observatory reveals no statistically significant excess 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 is derived for a dense grid
of directions for each of the four energy ranges. These results
constrain scenarios for the production of ultrahigh energy cosmic rays
in the Galaxy.
