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 sources, 32 of which are new VHE sources, significan...

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 r...

The Large High Altitude Air Shower Observatory (LHAASO) has officially released the precise energy spectrum for the highest-energy gamma-ray radiation from Gamma-Ray Burst (GRB) 221009A, the brightest GRB observed to date. This finding challenges the standard radiation model of GRB afterglows, re...
