Depth of Maximum of Air-Shower Profiles at the Pierre Auger Observatory — •Thomas Thomas for the Pierre Auger collaboration — Karlsruhe Institute of Technology, Institute for Astroparticle Physics, Karlsruhe, Germany
The Pierre Auger Observatory is the largest ultra-high energy cosmic ray observatory in the world. Using a hybrid technique (fluorescence telescopes and surface detectors) it is possible to estimate the mass composition of cosmic rays. The main mass-sensitive observable measured with fluorescence telescopes is the depth of maximum of air-shower profiles called Xmax.
In this presentation, we will present the analysis of the most recent datasets for the standard eyes and also for the low energy measurements performed with the High Elevation Auger Telescope (HEAT). This low energy measurements allow to study the energy region where the transition between Galactic and extragalactic cosmic rays is expected.
