The Pierre Auger Observatory: Unlocking the Secrets of Cosmic Rays

Ultra-high-energy cosmic rays (UHECRs) are a mystery. Scientists still don’t know where or how they are created. A new study combines three kinds of data measured at the Auger Observatory: the energy spectrum, shower maximum depth distributions, and arrival directions of UHECRs. Publication: A.A.
