Astronomers have discovered a record-breaking black hole moving at over 1,000 km/s, believed to have been ejected after ...

The central region around a galaxy is compact and emits a large amount of radiation of all different wavelengths across the electromagnetic spectrum. This region, known as AGN, has a high ...

AGN becomes a blazar when its directed jet points toward Earth ... The study proved that the nucleus of this galaxy stopped powering up its lobes because these structures existed from times past. The ...

also determine that the gas near the central galaxy exhibits only a low variation in its velocity. This suggests that the energy released by the AGN hosted in the central galaxy has a limited ...
