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
Cygnus A Stellar Mass Black Hole. Artist's illustration shows the black hole drawing mass from a companion blue star. The material forms a disc around the black hole before falling into it or being ejected by powerful jets.
Astronomers reveal supermassive black hole's intense magnetic field Astronomers from Chalmers University of Technology have used the giant telescope Alma to reveal an extremely powerful magnetic field very close to a supermassive black hole in a distant g
