Scientists have discovered that some supermassive black holes rotate much more rapidly than expected. The discovery came as ...
When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study 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.
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 ...
The researchers used the Atacama Large Millimeter/submillimeter Array (ALMA), combined with maser astrometry—a way to measure the positions of gas using microwaves—to trace the complete process of gas ...
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.
New simulations show flickering black hole signals arise from unstable shocks inside accretion discs, revealing how matter ...
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 ...
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 ...
"We know discs are vital to forming stars and planets in our galaxy, and here, for the first time, we're seeing direct evidence for this in another galaxy." When you purchase through links on our site ...
Starting from the upper left and moving clockwise from large to small scales: upper left —"spiral-like" system; upper right — "bar-like" structure; lower right — rotating infalling envelope; lower ...
