A new form of black hole archeology, linking spin to gas and dust, has revealed that these cosmic titans spin faster than ...
Observations from 2017 and 2018 by the Event Horizon Telescope have enhanced understanding of the supermassive black hole M87*, focusing on its turbulent accretion flow.
The speed at which a black hole spins is difficult to distinguish from the speed at which the surrounding flattened cloud of gas and dust — the accretion disk — rotates. "The challenge lies in ...
Data from NASA's Chandra X-ray Observatory reveals that black holes can cool gas to the proper temperature for a cosmic feast.
This material generates a flattened, swirling cloud of gas and dust called an accretion disk around the black hole. The tremendous mass of the supermassive black hole generates tidal forces and ...
"The problem is that mass is hard to measure, and spin is even harder." The speed at which a black hole spins is difficult to distinguish from the speed at which the surrounding flattened cloud of gas ...
U sing 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 ...
(Left) Artist’s impressions of a black hole and its accretion disk with different spins. (Right) the corresponding multiwavelength spectrum that would be observed in each one.
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 ...
