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

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%.
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

The Fluorescence Detector of the Pierre Auger Observatory

J. Abraham, +529 more
TL;DR: The Pierre Auger Observatory is a hybrid detector for ultra-high energy cosmic rays as discussed by the authors, which combines a surface array to measure secondary particles at ground level together with a fluorescence detector to measure the development of air showers in the atmosphere above the array.
Journal ArticleDOI

Measurement of the atmospheric neutrino-induced upgoing muon flux using MACRO

M. Ambrosio, +135 more
- 27 Aug 1998 - 
TL;DR: In this article, a measurement of the flux of neutrino-induced upgoing muons ( ν >∼ 100 GeV) using the MACRO detector is presented, where the ratio of the observed to expected events integrated over all zenith angles is 0.74 ± 0.036 (stat) ±0.13 (theoretical).
