The step-by-step process of gas transport to form accretion disks had not previously been understood. The researchers used the Atacama Large Millimeter/submillimeter Array (ALMA), combined with maser ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. An illustration of a black hole with an accretion disk, accompanied by diagrams showcasing the team's research. Astronomers have ...

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 ...

A research team from the Yunnan Observatories of the Chinese Academy of Sciences (CAS), in collaboration with other researchers, has developed a new method to estimate how stellar-mass compact objects ...

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 ...

Researchers at Tohoku University and Utsunomiya University have made a breakthrough in understanding the complex nature of turbulence in structures called "accretion disks" surrounding black holes, ...

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 ...

A schematic view of the history of the accretion disk and the intruding object. The three plots starting from the bottom left are snapshots from the numerical simulation, depicting the system at the ...

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.
