The Large High Altitude Air Shower Observatory (LHAASO) has accurately measured the cosmic ray all-particle energy spectrum and the mean logarithmic mass in the range of 0.3–30 peta-electronvolts (PeV). It has also discovered an “elbow” feature in the mean logarithmic mass spectrum of cosmic rays. The achievement, “Measur...
The Large High-Altitude Air Shower Observatory (LHAASO) officially published its first catalog of gamma-ray sources in the Astrophysical Journal Supplement Series on Feb. 27. The first LHAASO catalog contains 90 very-high-energy (VHE) gamma-ray so...
