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 ...

"Instead of Webb's 6.5-meter diameter, it's like we are observing this region with a 13-meter space telescope." ...

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 ...

New simulations show flickering black hole signals arise from unstable shocks inside accretion discs, revealing how matter ...

A newly identified quasar shows sustained growth beyond the Eddington limit, prompting new examination of accretion physics, radiation trapping and jet activity in early supermassive black holes.

Black holes themselves emit no light, but the matter spiralling into them forms a hot, dense accretion disc that radiates ...

Researchers accidentally stumbled on a way to measure the size of the accretion disks of dust, gas and plasma that surround black holes. When you purchase through links on our site, we may earn an ...

When astronomers look out into the cosmos, they see supermassive black holes (SMBH) in two different states. In one state, they're dormant. They're actively accreting only a tiny amount of matter and ...

Scientists smashed plasma jets together to create artificial accretion disks that could help reveal how black holes grow. When you purchase through links on our site, we may earn an affiliate ...

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 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 ...

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 ...
