Shower Maximum

We present the status and the recent measurements from the Pierre Auger Observatory. The energy spectrum is described and its features discussed. We report searches for anisotropy of cosmic rays arrival directions in large scales and through correlation with catalogues of celestial objects. The measurement of the cross section proton-air is discussed. Finally, the mass composition is addressed with the measurements of the variation of the depth of shower maximum with energy and with the muon density at ground.

Scientific Results

Since June 2008 the Pierre Auger Observatory, designed for the research of ultra high energy cosmic rays, is taking data in its final configuration. In this paper I will present a short overview of its recent scientific results. More specifically, I will discuss the all particle energy spectrum and the evidence for the GZK features, the measurement of the elongation rate and the resulting inferences on mass composition, the evidence for anisotropy in the subset of the highest energy events.

Arrival Directions

The Pierre Auger Observatory has been designed to investigate the origin and nature of the ultra high energy cosmic rays using a hybrid detection technique. A review of selected results is presented, with the emphasis given to the measurement of energy spectrum, mass composition and arrival directions.
