An improved limit to the diffuse flux of ultra-high energy neutrinos from the Pierre Auger Observatory
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +462
Neutrinos in the cosmic ray flux with energies near 1 EeV and above are detectable with the Surface Detector array of the Pierre Auger Observatory. We report here on searches throu…
Large scale distribution of ultra high energy cosmic rays detected at the Pierre Auger Observatory with zenith angles up to 80
The Pierre Auger Collaboration
We present the results of an analysis of the large angular scale distribution of the arrival directions of cosmic rays with energy above 4 EeV detected at the Pierre Auger Observat…
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…
Search for patterns by combining cosmic-ray energy and arrival directions at the Pierre Auger Observatory
The Pierre Auger Collaboration
Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-ener…
Depth of Maximum of Air-Shower Profiles at the Pierre Auger Observatory: Composition Implications
Pierre Auger Collaboration
Using the data taken at the Pierre Auger Observatory between December 2004 and December 2012, we have examined the implications of the distributions of depths of atmospheric shower…
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…
A Targeted Search for Point Sources of EeV Neutrons
The Pierre Auger Collaboration, A. Aab, P. Abreu +482
A flux of neutrons from an astrophysical source in the Galaxy can be detected in the Pierre Auger Observatory as an excess of cosmic-ray air showers arriving from the direction of…
A search for point sources of EeV photons
Pierre Auger Collaboration, A. Aab, P. Abreu +483
Measurements of air showers made using the hybrid technique developed with the fluorescence and surface detectors of the Pierre Auger Observatory allow a sensitive search for point…
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…
Ultrahigh Energy Neutrinos at the Pierre Auger Observatory
Pierre Auger Collaboration
The observation of ultrahigh energy (UHE) neutrinos has become a priority in experimental astroparticle physics. UHE neutrinos can be detected with a variety of techniques. In part…
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…
A Search for Point Sources of EeV Neutrons
The Pierre Auger Collaboration
A thorough search of the sky exposed at the Pierre Auger Cosmic Ray Observatory reveals no statistically significant excess of events in any small solid angle that would be indicat…
A search for anisotropy in the arrival directions of ultra high energy cosmic rays recorded at the Pierre Auger Observatory
Pierre Auger Collaboration
Observations of cosmic ray arrival directions made with the Pierre Auger Observatory have previously provided evidence of anisotropy at the 99% CL using the correlation of ultra hi…
