An international team of researchers studying data from China's Dark Matter Particle Explorer (DAMPE) has measured cosmic ray protons up to the energy of 100 TeV with high precision for the first time. In their paper published ...
Gamma-ray bursts, short and intense flashes of energetic radiation coming from outer space, are the brightest explosions in the universe. As gamma rays are blocked by the atmosphere, the bursts were discovered accidentally ...

Using NASA's Chandra X-ray observatory, astronomers have spotted X-ray-emitting clumps being ejected with high velocities from the gamma-ray binary PSR B1259–63/LS 2883. The findings were presented in a paper published ...
Using Major Atmospheric Gamma-ray Imaging Cherenkov (MAGIC) telescopes, an international group of astronomers has detected a fast, very high-energy (VHE) flare from the blazar BL Lacertae. The finding is detailed in a paper ...
During the formation of a black hole, a bright burst of very energetic light in the form of gamma rays is produced, these events are called gamma ray bursts. The physics behind this phenomenon includes many of the least understood ...
