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

Observation of the suppression of the flux of cosmic rays above 4x10(19) eV

J. Abraham, +488 more
TL;DR: The energy spectrum of cosmic rays above 2.5 x 10;{18} eV, derived from 20,000 events recorded at the Pierre Auger Observatory, is described and the hypothesis of a single power law is rejected with a significance greater than 6 standard deviations.
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

The major upgrade of the MAGIC telescopes, Part II: A performance study using observations of the Crab Nebula

Jelena Aleksić, +164 more
TL;DR: In this paper, the MAGIC-I camera and its trigger system were replaced with a new one for low and medium zenith angles to assess the key performance parameters of MAGIC stereo system for point-like sources with Crab Nebula-like spectrum.
Journal ArticleDOI

Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei

J. Abraham, +483 more
TL;DR: In this paper, the Pierre Auger Observatory data was used to confirm the anisotropy of the arrival direction of the highest-energy cosmic rays with the highest energy, which are correlated with the positions of relatively nearby active galactic nuclei (AGN) at a confidence level of more than 99%.
