Do the most energetic particles in the uni-verse come from supermassive black holes? New results from the Pierre Auger Observatory make that case.

The Pierre Auger Collaboration has begun the public release of one percent of the cosmic-ray events recorded by the Observatory in Argentina. New cosmic-ray data—about 70 events per day—will be posted on a daily basis.

Un Ciel Dégagé Pour Le Laboratoire Pierre Auger

Quelle est l’origine des rayons cosmiques? C’est pour résoudre cette énigme que des chercheurs ont investi la pampa argentine.

The most energetic particles in the universe have a message for us. The gigantic Pierre Auger Southern Observatory, still under construction in Argentina, is already trying to decipher it.

The Pierre Auger Observatory is a topic in many magazines and journals.
