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

Properties and performance of the prototype instrument for the Pierre Auger Observatory

J. Abraham, +356 more
TL;DR: The first phase of the Pierre Auger Observatory has been completed and all of the sub-systems that will be used in the full instrument to be tested under field conditions as discussed by the authors.
Journal ArticleDOI

Relic neutrino decoupling including flavour oscillations

TL;DR: In this article, the effect of three-neutrino flavour oscillations on the decoupling process of neutrinos has been studied by solving the momentum-dependent kinetic equations for the neutrino spectra.
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

Primordial nucleosynthesis: From precision cosmology to fundamental physics

TL;DR: In this paper, an up-to-date review of Big Bang Nucleosynthesis (BBN) is presented, and the main improvements which have been achieved in the past two decades on the overall theoretical framework, summarize the impact of new experimental results on nuclear reaction rates, and critically re-examine the astrophysical determinations of light nuclei abundances.
