Spectral Calibration of the Fluorescence Telescopes of the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Aab, P. Abreu +403

We present a novel method to measure precisely the relative spectral response of the fluorescence telescopes of the Pierre Auger Observatory. We used a portable light source based…

Probing the origin of ultra-high-energy cosmic rays with neutrinos in the EeV energy range using the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Aab, P. Abreu +389

Neutrinos with energies above eV are detectable with the Surface Detector Array of the Pierre Auger Observatory. The identification is efficiently performed for neutrinos…

Inferences on Mass Composition and Tests of Hadronic Interactions from 0.3 to 100 EeV using the water-Cherenkov Detectors of the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Aab, P. Abreu +403

We present a new method for probing the hadronic interaction models at ultra-high energy and extracting details about mass composition. This is done using the time profiles of the…

Observation of inclined EeV air showers with the radio detector of the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Aab, P. Abreu +392

With the Auger Engineering Radio Array (AERA) of the Pierre Auger Observatory, we have observed the radio emission from 561 extensive air showers with zenith angles between 60$^\ci…

Measurement of the fluctuations in the number of muons in extensive air showers with the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Aab, P. Abreu +365

We present the first measurement of the fluctuations in the number of muons in extensive air showers produced by ultrahigh energy cosmic rays. We find that the measured fluctuation…

Reconstruction of Events Recorded with the Surface Detector of the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Aab, P. Abreu +378

Cosmic rays arriving at Earth collide with the upper parts of the atmosphere, thereby inducing extensive air showers. When secondary particles from the cascade arrive at the ground…
