The image of M87*, the supermassive black hole at the center of massive elliptical galaxy M87, changed the world. It was the ...

Scientists used changes in the supermassive black hole M87*'s accretion disk to infer its orientation, size and turbulence ...

Some of this glowing matter envelops the black hole in a whirling region called an accretion disk. Even the matter that starts falling into a black hole isn't necessarily there to stay.

The interferometer team, led by Steve Ertel, associate astronomer of Steward Observatory, observed several phenomena ...

How much does a black hole change in a year? Scientists may now have an idea, after taking a fresh look at the first-ever black hole to be imaged — the supermassive black hole M87*, , which ...

matching theoretical predictions for the shadow of a 6.5 billion solar-mass black hole. The brightest part of the ring is shifted 30 degrees counter-clockwise, due to turbulence in the accretion disk.

1). While current X-ray observatories cannot directly image the accretion disk, X-ray spectra can be used to learn about the spacetime (e.g., is the black hole spinning?) and accretion disk close to ...
