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 ...

NASA has released a stunning new video and images visualizing the distortion you would see if you observed two black holes, and their visible accretion disks, orbiting each other. The visualization ...

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 ...

Black holes are regions of austere darkness, gobbling up everything — even light — that strays too close. But the environment immediately surrounding a black hole is not so dark. Astronomers often ...

Accretion is one of the most fundamental processes in the cosmos. It is a universal phenomenon triggered by gravity, and the process by which bits of matter accumulate and coalesce with more bits of ...

Supermassive black holes may tear apart and devour their disk of surrounding dust and gas at a shocking speed, perhaps explaining the behavior of a mysterious class of rapidly brightening quasar.

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 ...

A close encounter more than 10,000 years ago stirred up spirals in the accretion disk surrounding the black hole at the center of our galaxy. Dr. LU Xing, an associate researcher from the Shanghai ...

A model of ultraviolet and optical emission from the tidal disruption event AT 2018hyz is shown in this schematic diagram. As an accretion disk forms quickly after the TDE, it generates x-ray emission ...

Interacting binary stars, a class of stellar systems consisting of two gravitationally bound stars, exhibit a rich diversity of phenomena driven by mass transfer and angular momentum exchange. In many ...

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.
