New measurements from an observatory in Argentina suggest that all the most energetic cosmic rays arise from the same types of extragalactic accelerators.
Scientific Highlights
Recently, the Pierre Auger Collaboration systematically studied the distribution of ultra-high-energy cosmic rays at an intermediate angular scale...
When ESA's groundbreaking Aeolus satellite began experiencing a mysterious signal loss in 2019, help came from the Pierre Auger Observatory.
As part of the AugerPrime upgrade, scintillator detectors (SSD) have been added to the existing water-Cherenkov surface detector stations.
