The study, carried out by two researchers at the Instituto de Astrofísica de Canarias, shows that the “change in position” observed in the nucleus of the galaxy M87 is not due to a displacement of its supermassive black hole, but to variations in the emission of light in the centre of the galaxy caused by outbursts coming from its jet, a flow of relativistic material along a narrow beam, emitted from just outside the black hole itself.
