Massive central black holes in galaxies have the most powerful jets, but their structure and behaviours are similar to those of smaller galactic neutron stars and black holes. These SMBH systems are often called microquasars and show a large range of velocities. SS 433 jet, for example, has a mean velocity of 0.26c. [9]
[4] [5] The giant black hole jet system was named after Porphyrion, a Giant from Greek mythology, by co-discoverer Aivin Gast from the University of Oxford. [6] To find the galaxy from which Porphyrion originated, the Giant Metrewave Radio Telescope in India was used along with ancillary data from the Dark Energy Spectroscopic Instrument in ...
However, astronomers have long questioned whether long, powerful jets could be spotted in the distant universe because the black holes responsible for them behaved differently in the early ...
A 2010 paper suggested that the black hole may be displaced from the galactic center by about seven parsecs (23 light-years). [79] This was claimed to be in the opposite direction of the known jet, indicating acceleration of the black hole by it. Another suggestion was that the offset occurred during the merger of two supermassive black holes.
Astronomers have spotted a massive pair of jets releasing material from a distant black hole. The jets are so large they span about 140 Milky Way galaxies in length.
PSO J352.4034–15.3373, or PJ352-15, is a quasar with an astrophysical jet ascribed to a billion-solar-mass supermassive black hole. It is one of the brightest objects so far discovered. Its discovery, using the Chandra X-Ray Observatory, was reported in March 2021. At 12.7 billion light years from Earth, the X-ray jet became an observational ...

The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list.. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.
