Mysterious cosmic rays linked to galactic powerhouses
11-08-2007 · EurekAlert!The sprawling Auger Cosmic Ray Observatory in South America has produced its first major discovery while still under construction. The international Auger collaboration has traced the rain of high-energy cosmic rays that continually pelts the Earth to the cores of nearby galaxies, which emit prodigious quantities of energy.

- Auger Observatory closes in on mystery, links highest-energy cosmic rays with violent black holes
11-08-2007 · EurekAlert!
The Pierre Auger Collaboration announced that active galactic nuclei are the most likely candidate for the source of the highest-energy cosmic rays that hit Earth. Using the Pierre Auger Observatory in Argentina, the team of scientists found that the sources of the highest-energy particles are not distributed uniformly across the sky. Instead, the Auger results link the origins of these mysterious particles to the locations of nearby galaxies that have active nuclei in their centers.

- New experiment to investigate the effect of galactic cosmic rays on clouds and climate
10-23-2006 · EurekAlert!
A novel experiment, known as CLOUD (Cosmics Leaving OUtdoor Droplets), begins taking its first data today with a prototype detector in a particle beam at CERN , the world's largest laboratory for particle physics. The goal of the experiment is to investigate the possible influence of galactic cosmic rays on Earth's clouds and climate. This represents the first time a high energy physics accelerator has been used for atmospheric and climate science.

- Scientists discover a connection between active galactic nuclei and cosmic rays
12-19-2007 · EurekAlert!
'Science' has published the results of this research. The so-called Pierre Auger Collaboration, with headquarters in Argentina and participation from the UGR, has proved that there is an anisotropy in the arrival directions of the most energetic particles ever detected, correlated with areas in which there are galaxies with active nuclei in the centre. These conclusions have been obtained from the first data provided by the Pierre Auger Observatory of the Southern Hemisphere in Argentina.

- Auger Observatory links highest-energy cosmic rays with violent black holes
11-08-2007 · EurekAlert!
Scientists of the Pierre Auger Collaboration, which includes New York University physics professor Glennys R. Farrar, have concluded that active galactic nuclei are the most likely candidate for the source of the highest-energy cosmic rays that hit Earth. Using the Pierre Auger Observatory in Argentina, a team of scientists from 17 countries found that the sources of the highest-energy particles are nearby galaxies that have active nuclei in their centers.
