Ultra-high energy cosmic rays - Recent results and status of the Pierre Auger Observatory — •Daniela Mockler for the Pierre Auger collaboration — Institut für Experimentelle Teilchenphysik, Karlsruhe Institut für Technologie
The Pierre Auger Observatory is the world’s largest detector arrangement for detecting extensive air showers initiated by cosmic rays with energies above 3×1017 eV. Equipped with 1660 water-Cherenkov stations, the surface detector array (SD) spans an area of 3000 km2. The combination with 27 fluorescence telescopes (FD) that overlook the atmosphere and measure the calorimetric energy allows for a hybrid detection. The Pierre Auger Observatory is extended by buried scintillators for a direct muon detection (AMIGA) as well as radio antennas measuring the emission of radio signals from air showers (AERA). The current upgrade (AugerPrime) with scintillators on top of each detector station will allow the discrimination between the electromagnetic and muonic shower components. Thus, it will extend the sensitivity for primary masses which allows for an improved search for possible sources of cosmic rays at the highest energies.
An overview of the latest results and the current status of the Pierre Auger Observatory will be given in this talk.
