Multi-wavelength calibration procedure for the Pierre Auger Observatory fluorescence detectors
(Elsevier Science, 2009-12)
We present a method to measure the relative spectral response of the Pierre Auger Observatory Fluorescence Detector. The calibration was done at wavelengths of 320, 337, 355, 380 and 405 nm using an end-to-end technique ...
Ultra-high energy neutrinos at the Pierre Auger Observatory
(Sociedade Brasileira de Fisica, 2016)
Neutrinos in the sub-EeV energy range and above can be detected with the Surface Detector (SD) of the Pierre Auger Observatory. They can be identified through the broad time structure of the signals induced in the SD ...
The muon content of hybrid events recorded at the Pierre Auger Observatory
(The International Union of Pure and Applied Physics, 2014)
The hybrid events of the Pierre Auger Observatory are used to test the leading, LHC-tuned, hadronic interaction models. For each of 411 well-reconstructed hybrid events collected at the Auger Observatory withenergy 10E18.8 ...
An upper limit to the photon fraction in cosmic rays above 1019 eV from the Pierre Auger Observatory
(2007)
An upper limit of 16% (at 95% c.l.) is derived for the photon fraction in cosmic rays with energies greater than 1019 eV, based on observations of the depth of shower maximum performed with the hybrid detector of the Pierre ...
Measurement of the energy spectrum of cosmic rays above '10 POT.18' eV using the Pierre Auger Observatory
(ElsevierAmsterdam, 2010-03)
We report a measurement of the flux of cosmic rays with unprecedented precision and statistics using the Pierre Auger Observatory. Based on fluorescence observations in coincidence with at least one surface detector we ...
The exposure of the hybrid detector of the Pierre Auger Observatory
(2011)
The Pierre Auger Observatory is a detector for ultra-high energy cosmic rays. It consists of a surface array to measure secondary particles at ground level and a fluorescence detector to measure the development of air ...
