Astronomers from the Chinese Academy of Sciences (CAS) and elsewhere report the detection of a new ultra-high energy (UHE) gamma-ray source in the Galactic plane. The newly identified source, designated LHAASO J0341+5258, ...
Using the Large High Altitude Air Shower Observatory (LHAASO), astronomers have performed a search for new high-energy gamma-ray sources. As a result, they have identified a new ultra-high energy gamma-ray source, which received ...
A new study based on high-quality radio observations with the Karl G. Jansky Very Large Array (VLA) has investigated the origin of a very high-energy gamma-ray source known as VER J1907+062. Results of the study, published ...
The strongest explosions in the universe produce even more energetic radiation than previously known: Using specialized telescopes, two international teams have registered the highest energy gamma rays ever measured from ...

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 ...
Researchers have identified a new blazar-like narrow-line Seyfert 1 galaxy that emits gamma-ray radiation. The new galaxy, designated SDSS J211852.96−073227.5, could offer insights into formation and evolution of jets of ...
In April 2015, after traveling for about half the age of the universe, a flood of powerful gamma rays from a distant galaxy slammed into Earth's atmosphere. That torrent generated a cascade of light - a shower that fell onto ...
