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 ...

Figure 1: P Cyg profiles observed during days 2, 6, 7–9 and 10 in He I λ = 5,876 Å. The sustained disk wind that we have discovered in V404 Cyg could be a new fundamental driver in the accretion ...

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 ...

Our project will increase the spatial resolution reachable in the optical by thousands, opening new fields of investigation in astronomy in general. For instance, images could be obtained of 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.

Some supermassive black holes announce their presence with screaming hot disks of orbiting gases. But the behemoth at the center of the Milky Way has been shy and demure. Now, astronomers have finally ...

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 ...

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 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 ...

Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the stars rotate, gas and dust accumulates in a rotating disk around the star ...
