A search for point sources of EeV photons

Understand

Measurements of air showers made using the hybrid technique developed with the fluorescence and surface detectors of the Pierre Auger Observatory allow a sensitive search for point sources of EeV photons anywhere in the exposed sky.

• A multivariate analysis reduces the background of hadronic cosmic rays.
• The search is sensitive to a declination band from -85{\deg} to +20{\deg}, in an energy range from 10^17.3 eV to 10^18.5 eV.
• No photon point source has been detected.
