This helped to constrain the size of the accretion disk as the team could see the hydrogen line comes from a distance of 16.77 light-days from the central supermassive black hole, while the oxygen ...

They found the black hole's accretion disk emits a constant stream of flares with no periods of rest. This video shows the 2.1 micron data taken on April 7, 2024.
An artist’s illustration depicts the supermassive black hole at the center of the Milky Way galaxy, known as Sagittarius A*. It’s surrounded by a swirling accretion disk of hot gas and dust.
Accretion, not colliding spaghetti, flares up as star is devoured by black hole. In their experiment, the researchers were able to control both the liquid’s rotation speed, and its level of turbulence ...
This is the first time that astronomers have seen an accretion disc in an extragalactic area. The discovery is described in a study published November 29 in the journal Nature .
The gas in the black hole’s accretion disk had levels of nitrogen up to 100 times than the Sun’s and much lower levels of carbon (only about 40 percent of what the Sun contains).
For the first time, astronomers have glimpsed a young star outside the Milky Way galaxy that’s ringed by a dense disk where planets may form. The massive star, called HH 1177, and its rotating ...
The material that PSR J1023 strips from its companion star forms an accretion disk around the pulsar. This material, full of highly energetic charged particles, is pulled inward by the pulsar’s ...
To put that in perspective, the inner edge of its accretion disk is whipping around at about 14% the speed of light—that's around 42 million meters per second.
Astronomers believe the flares are coming from the inner edge of the accretion disk just beyond the black hole’s event horizon, or the area around a black hole where the pull of gravity is so ...
Lab top accretion disc: Cutaway diagram of the experimental setup used by Wang and colleagues. The data shown in the left portion of the gap between cylinders illustrates the simulated shear profile ...
