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 ...

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 ...

I asked my friend Julie Ménard how Earth formed. She’s a planetary scientist at Washington State University. She told me it started with the Big Bang. That was nearly 14 billion years ago. “The Big ...

An image of Pōwehi, a supermassive black hole in the galaxy Messier 87. This image, which is the most detailed to date taken of a black hole, uses polarized light to reveal relativistic jets (in ...

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.

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 ...

This disk-like structure emitting thermal light is called an accretion disk. Note that other objects can also lead to accretion disk, like a forming planet or star.

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, by definition, places where gravity is so strong, not even light can escape. So, they’re black — dark — and impossible to image. Right? Why is there a disk at all? Can’t all the ...

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 ...

Quasars initially confused astronomers when they were discovered. First identified as sources of radio-frequency radiation, later observations showed that the objects had optical counterparts that ...
