A new method to measure the attenuation of hadrons in extensive air showers
W. D. Apel
Extensive air showers are generated through interactions of high-energy cosmic rays impinging the Earth's atmosphere. A new method is described to infer the attenuation of hadrons…
Test of the hadronic interaction model EPOS with air shower data
Grande Collaboration, W. D. Apel
Predictions of the hadronic interaction model EPOS~1.61 as implemented in the air shower simulation program CORSIKA are compared to observations with the KASCADE experiment. The in…
Anisotropy studies around the galactic centre at EeV energies with the Auger Observatory
The Pierre Auger Collaboration
Data from the Pierre Auger Observatory are analyzed to search for anisotropies near the direction of the Galactic Centre at EeV energies. The exposure of the surface array in this…
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…
