Large Hubble Survey Confirms Link between Mergers and Supermassive Black Holes with Relativistic Jets
A team of astronomers using the Hubble Space Telescope found an unambiguous link between the presence of supermassive black holes that power high-speed, radio-signal-emitting jets and the merger history of their host galaxies. Almost all galaxies with the jets were found to be merging with another galaxy, or to have done so recently.
