Journal ArticleDOI

Correlation of the highest-energy cosmic rays with nearby extragalactic objects.

J. Abraham, +452 more
- 09 Nov 2007 - 
TL;DR: In this article, the authors demonstrate that there is a correlation between the arrival directions of cosmic rays with energy above 6 x 10{sup 19} eV and the positions of active galactic nuclei lying within 75 Mpc.
Journal ArticleDOI

Measurement of the energy spectrum of cosmic rays above 10(18) eV using the Pierre Auger Observatory

J. Abraham, +492 more
- 08 Mar 2010 - 
TL;DR: In this article, the authors reported a measurement of the flux of cosmic rays with unprecedented precision and statistics using the Pierre Auger Observatory based on fluorescence observations in coincidence with at least one surface detector.
Journal ArticleDOI

Update on the correlation of the highest energy cosmic rays with nearby extragalactic matter

P. Abreu, +495 more
TL;DR: In this paper, anisotropy was measured by the fraction of arrival directions that are less than 3.1 degrees from the position of an active galactic nucleus within 75 Mpc (using the Veron-Cetty and Veron 12th catalog).
Journal ArticleDOI

Measurement of the proton-air cross section at √s=57 TeV with the Pierre Auger Observatory.

P. Abreu, +521 more
TL;DR: A measurement of the proton-air cross section for particle production at the center-of-mass energy per nucleon of 57 TeV is reported, derived from the distribution of the depths of shower maxima observed with the Pierre Auger Observatory.
Journal ArticleDOI

Upper limit on the diffuse flux of ultrahigh energy tau neutrinos from the Pierre Auger Observatory

J. Abraham, +467 more
TL;DR: The surface detector array of the Pierre Auger Observatory is sensitive to Earth-skimming tau neutrinos that interact in Earth's crust to place an upper limit on the diffuse flux of nu(tau) at EeV energies.
