An illustration of a black hole with an accretion disk, accompanied by diagrams showcasing the team's research. Astronomers have observed the outer edge of a disk of matter surrounding a feeding ...

Black holes exert a tremendous influence on their surroundings, meaning that when they spin, they literally drag the very fabric of space and time around with them. That means nothing can sit still ...

Quasars and active galactic nuclei (AGN) are likely powered by matter accretion onto a super-massive black hole located at their center. Before being swallowed by the black hole, matter spirals ...

Researchers conducted innovative simulations of spinning black holes grounded in general relativity, which clarified that the ultraluminous accretion disk (i.e., gaseous spiral surrounding a black ...

To understand the mysteries surrounding black holes, researchers at Tohoku University have created a simulation of accretion disk turbulence that possesses the highest-resolution currently available.

An international scientific team has revealed for the first time the magnetic field transport processes in the accretion flow of a black hole and the formation of a "MAD"—a magnetically arrested ...

Black hole accretion processes remain at the forefront of astrophysical research, offering critical insights into how matter is captured by these extreme objects. Accretion occurs when gas, dust, and ...

Astronomers have viewed the outer region of an active supermassive black hole's accretion disk, thereby improving our understanding of these feeding cosmic monsters. When you purchase through links on ...

Artistic image of accretion disk turbulence. The inset is the magnetic field fluctuations computed by the simulation of this study. Researchers at Tohoku University and Utsunomiya University have made ...
