Argentinian astronomers have conducted radio observations of a very-high-energy gamma-ray source known as HESS J1857+026. Results of this study provide new insights into the nature of this mysterious source. The research ...

Astronomers detect ultra-high energy gamma-ray source

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, ...

New ultra-high energy gamma-ray source detected

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 ...
