Study sheds more light on the nature of HESS J1857+026

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 ...

HESS J1943+213 is an extreme blazar, study finds

An international group of astronomers have carried out multi-wavelength observations of HESS J1943+213 and found evidence supporting the hypothesis that this gamma-ray source is an extreme blazar. The finding is reported ...

Fermi finds record-breaking binary in galaxy next door

Using data from NASA's Fermi Gamma-ray Space Telescope and other facilities, an international team of scientists has found the first gamma-ray binary in another galaxy and the most luminous one ever seen. The dual-star system, ...

Fermi data tantalize with new clues to dark matter

(Phys.org) —A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe. ...
