The Large High Altitude Air Shower Observatory (LHAASO) officially released the precise measurements of high-energy gamma radiation from the W51 complex, confirming it as a cosmic-ray accelerator boosting particles up to so-called ultra-high energies (UHE, above 1014 electronvolts). This study al...

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 discovered a giant ultra-high-energy gamma-ray bubble structure in the Cygnus star-forming region, which is the first time in human history that the origin of cosmic rays with energy higher than 10 Peta-Electronvolt (PeV, 1PeV=1015eV) ha...

In recognition of research groups or individuals who have completed or demonstrated significant achievements within the past five years, the Chinese Academy of Sciences (CAS) awarded the 2023 Outstanding Science and Technology Achievement Prize on Dec. 23, 2023. The research group of Large High ...

New research findings on the gamma-ray burst (GRB) named GRB 221009A from the Large High Altitude Air Shower Observatory (LHAASO) were published online by the journal Science on June 8, 2023. The study, entitled "A tera-electronvolt afterglow from a narrow jet in an extremely bright GRB 221009A",...

The Large High Altitude Air Shower Observatory (LHAASO) project, one of China's major national scientific and technological infrastructure facilities, has successfully passed national acceptance and formally gone into operation. LHAASO is a facility focusing on cosmic ray observation and research...

Scientists from the Large High Altitude Air Shower Observatory (LHAASO) have presented roughly 1.5 years of observational data, calculating new limits on the lifetime of heavy dark matter particles that have masses between 10^5 and 10^9 giga-electron volts. The study, entitled “Constraints on he...

Researchers from the Institute of High Energy Physics of the Chinese Academy of Sciences examined the validity of the theory of relativity with the highest accuracy in a study entitled “Exploring Lorentz Invariance Violation from Ultrahigh-Energy γRays Observed by LHAASO,” which was published ...
