Description

Authorship: The Pierre Auger Collaboration The Pierre Auger Observatory is measuring the ultra-high energy cosmic ray extended air showers from simultaneous observation of fluorescence and surface detectors with unprecedented precision. The high statistics of the surface detector allows a good determination of the cosmic ray flux above an energy of 3 EeV. This bound is extended down to 1 EeV using a unique technique that exploits the hybrid detection power. The spectrum is presented displaying two clear features in the energy range between 1 and 100 EeV.
