A Targeted Search for Point Sources of EeV Photons with the Pierre Auger Observatory

Mostrar todas las versiones(2)

Simultaneous measurements of air showers with the fluorescence and surface detectors of the Pierre Auger Observatory allow a sensitive search for EeV photon point sources. Several Galactic and extragalactic candidate objects are grouped in classes to reduce the statistical penalty of many trials fro...
