Resumen:
Abstract: The Pierre Auger Observatory, located in Argentina, provides an unprecedented exposure for detecting photons with energies above 10E17 eV over most of the sky. In this work, the information from the surface array of water Cherenkov detectors and from the fluorescence telescopes of the Observatory, are combined in a multivariate analysis to search for photons in the EeV energy range. The arrival directions of candidate photons in the Auger Observatory are here analyzed for the first time. No photon point source is detected. Upper limits on regularlyemitting non-beamed photon sources in the Galaxy do not exceed 0.25 eV cm−2 s−1 and constrain models for the acceleration in the Galaxy of the EeV protons.
