Upper limit on the cosmic-ray photon fraction at EeV energies from the Pierre Auger Observatory
The Pierre Auger Collaboration, J. Abraham, P. Abreu +458
From direct observations of the longitudinal development of ultra-high energy air showers performed with the Pierre Auger Observatory, upper limits of 3.8%, 2.4%, 3.5% and 11.7% (a…

The Absolute, Relative and Multi-Wavelength Calibration of the Pierre Auger Observatory Fluorescence Detectors
R. Knapik, P. Bauleo, B. R. Becker +20
Absolute calibration of the Pierre Auger Observatory fluorescence detectors uses a 375 nm light source at the telescope aperture. This end-to-end technique accounts for the combine…
