Title: First cosmic-ray grapes ripen in Argentina: Results and progress of the Pierre Auger Observatory
Abstract: The Pierre Auger Observatory is the largest detector ever built for the study of ultra‐high energy cosmic rays. The construction of its southern site in Mendoza Province in Argentina is almost complete and the observatory has been acquiring scientific data for more than two years. The cumulative exposure achieved during this period is greater than the exposure of any forerunner experiment. Furthermore, the Pierre Auger Observatory uses the innovative hybrid technique which combines the advantages of fluorescence telescopes (precise and nearly model‐independent energy measurement) and the advantages of surface detector arrays (exact geometrical definition of exposure). A preliminary analysis of this initial data set will be presented, namely the spectrum and the results of anisotropy searches.
