Chinese Astronomers Discover Giant Ultra-High-Energy Gamma-Ray Bubble

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 that the origin of cosmic rays with energy higher than 10 Peta-Electronvolt (PeV, 1PeV=1015eV) has been discovered.

This achievement was published in the form of a cover article in Science Bulletin on February 26.

The research was completed by the LHAASO Collaboration led by Prof. Cao Zhen as the spokesperson from the Institute of High Energy Physics of the Chinese Academy of Sciences. Dr. Gao Chuandong, Dr. Li Cong, Prof. Liu Ruoyu, and Prof. Yang Ruizhi are the co-corresponding authors of the paper.
