Multifrequency observations explore radio galaxy 3C 111 and its jet
Using the Very Long Baseline Array (VLBA), European astronomers have carried out multi-wavelength radio observations of a radio galaxy designated 3C 111. Results of the observational campaign, published March 24 on the arXiv ...
Jets from powerful black holes can point astronomers toward where to look for life in the universe
One of the most powerful objects in the universe is a radio quasar—a spinning black hole spraying out highly energetic particles. Come too close to one, and you'd get sucked in by its gravitational pull, or burn up from ...
