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 ...

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 ...

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.

A lonely world drifting through space with no star to orbit is gorging on gas and dust at a staggering pace, swallowing ...

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 ...

Astronomers have viewed the outer region of an active supermassive black hole's accretion disk, thereby improving our understanding of these feeding cosmic monsters. When you purchase through links on ...

Artistic image of accretion disk turbulence. The inset is the magnetic field fluctuations computed by the simulation of this study. Researchers at Tohoku University and Utsunomiya University have made ...
