The 2018 observations confirmed the luminous ring seen in 2017, with a diameter of about 43 microarcseconds, matching theoretical predictions for the shadow of a 6.5 billion solar-mass black hole. The ...

A new computer simulation suggests this prolonged existence of accretion disks may owe itself to each disk being almost completely controlled by the magnetic fields of its respective black hole.

Using observations from 2017 and 2018, the Event Horizon Telescope (EHT) Collaboration has advanced our understanding of the supermassive black hole at the center of Messier 87 (M87*). This study ...

allows us to probe the properties of the black hole itself. We numerically model the appearance of these systems in X-rays (see Fig. 1). While current X-ray observatories cannot directly image the ...

When matter is fed to a black hole from the flattened cloud of matter around it called an accretion disk, that matter can spiral inwards in the direction that the black hole spins in — or ...
