Measurement of the Muon Production Depths at the Pierre Auger Observatory
Laura Collica
The muon content of extensive air showers is an observable sensitive to the primary composition and to the hadronic interaction properties. The Pierre Auger Observatory uses water-…
Searches for Anisotropies in the Arrival Directions of the Highest Energy Cosmic Rays Detected by the Pierre Auger Observatory
Pierre Auger Collaboration
We analyze the distribution of arrival directions of ultra-high energy cosmic rays recorded at the Pierre Auger Observatory in 10 years of operation. The data set, about three time…
Depth of Maximum of Air-Shower Profiles at the Pierre Auger Observatory: Measurements at Energies above 10^17.8 eV
Pierre Auger Collaboration
We report a study of the distributions of the depth of maximum, Xmax, of extensive air-shower profiles with energies above 10^17.8 eV as observed with the fluorescence telescopes o…
Muons in air showers at the Pierre Auger Observatory: Mean number in highly inclined events
Pierre Auger Collaboration
We present the first hybrid measurement of the average muon number in air showers at ultra-high energies, initiated by cosmic rays with zenith angles between and $80^\ci…
Muons in air showers at the Pierre Auger Observatory: Measurement of atmospheric production depth
Pierre Auger Collaboration
The surface detector array of the Pierre Auger Observatory provides information about the longitudinal development of the muonic component of extensive air showers. Using the timin…
Probing the radio emission from air showers with polarization measurements
Pierre Auger Collaboration
The emission of radio waves from air showers has been attributed to the so-called geomagnetic emission process. At frequencies around 50 MHz this process leads to coherent radiatio…
Constraints on the origin of cosmic rays above eV from large scale anisotropy searches in data of the Pierre Auger Observatory
Pierre Auger Collaboration
A thorough search for large scale anisotropies in the distribution of arrival directions of cosmic rays detected above eV at the Pierre Auger Observatory is reported. For…
Large scale distribution of arrival directions of cosmic rays detected above eV at the Pierre Auger Observatory
Pierre Auger Collaboration
A thorough search for large scale anisotropies in the distribution of arrival directions of cosmic rays detected above eV at the Pierre Auger Observatory is presented. Th…
Atmospheric aerosols at the Pierre Auger Observatory and environmental implications
K. Louedec
The Pierre Auger Observatory detects the highest energy cosmic rays. Calorimetric measurements of extensive air showers induced by cosmic rays are performed with a fluorescence det…
Description of Atmospheric Conditions at the Pierre Auger Observatory Using Meteorological Measurements and Models
Bianca Keilhauer, Martin Will
Atmospheric conditions at the site of a cosmic ray observatory must be known well for reconstructing observed extensive air showers, especially when measured using the fluorescence…
Measurement of the proton-air cross-section at TeV with the Pierre Auger Observatory
Pierre Auger Collaboration
We report a measurement of the proton-air cross-section for particle production at the center-of-mass energy per nucleon of 57 TeV. This is derived from the distribution of the dep…
An upper limit to the photon fraction in cosmic rays above 10^19 eV from the Pierre Auger Observatory
Pierre Auger Collaboration
An upper limit of 16% (at 95% c.l.) is derived for the photon fraction in cosmic rays with energies greater than 10^19 eV, based on observations of the depth of shower maximum perf…
Quality studies of the data taking conditions for the Auger Fluorescence Detector
R. Caruso, R. Fonte, A. Insolia +3
As more than half of the Fluorescence Detector (FD) of the Auger Observatory is completed, data taking is becoming a routine job. It is then necessary to follow strict procedures t…
Statistical and systematic uncertainties in the event reconstruction and S(1000) determination by the Pierre Auger surface detector
Pierre Auger Collaboration
We discuss the statistical and systematic uncertainties in the event reconstruction (core location, and determination of S(1000), i.e., the signal at a distance of 1000 m from the…
