A team of researchers at the Chinese Academy of Sciences has found evidence of a powerful particle accelerator in the galactic center. In their paper published in the journal Nature Communications, the group describes their ...
Star-forming galaxies are responsible for creating gamma-rays that until now had not been associated with a known origin, researchers from The Australian National University (ANU) have confirmed.
