Correlation of the highest energy cosmic rays with nearby extragalactic objects
Using data collected at the Pierre Auger Observatory during the past 3.7 years, we demonstrate that there is a correlation between the arrival directions of cosmic rays with energy above {approx} 6 xExpand

Measurement of the depth of maximum of extensive air showers above 10{18} eV.
We describe the measurement of the depth of maximum, X{max}, of the longitudinal development of air showers induced by cosmic rays. Almost 4000 events above 10;{18} eV observed by the fluorescenceExpand
