The Auger Engineering Radio Array (AERA) measures radio properties of cosmic-ray induced air showers within the Pierre Auger Observatory.
Scientists home in on the make-up of cosmic rays, which are more nuanced than previously thought.
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.
