Gargantuan Black Hole Jets Are Biggest Seen Yet
The jumbo jets blast hot plasma well beyond their own host galaxy.
To find the galaxy from which Porphyrion originated, the team used the Giant Metrewave Radio Telescope(GMRT) in India along with ancillary data from a project called Dark Energy Spectroscopic Instrument(DESI), which operates from Kitt Peak National Observatory in Arizona. Keck Observatory in Hawai‘iImage LightboxThe fact that Porphyrion came from a radiative-mode black hole came as a surprise because astronomers did not know this mode could produce such huge and powerful jets. "Martijn's work has shown us that there isn't anything particularly special about the environments of these giant sources that causes them to reach those large sizes," says Hardcastle, who is an expert in the physics of black hole jets.
