An international team led by a researcher at the Chiba Institute of Technology has discovered an extremely rare phenomenon: a ...

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 ...

Astronomers studying a quasar roughly 10 billion light-years from Earth have documented one of the most extreme dimming ...

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 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 ...

New UNLV-led research is helping to unravel clues to a cosmic mystery that has eluded scientists for decades. Cataclysmic ...

There’s a pretty hot party raging in the black hole at the center of our galaxy. Using new observations from NASA’s James Webb Space Telescope (JWST), a team of astrophysicists found that the swirling ...

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 ...

Interacting binary stars, a class of stellar systems consisting of two gravitationally bound stars, exhibit a rich diversity of phenomena driven by mass transfer and angular momentum exchange. In many ...

In December 2020, astronomers spotted an unusual burst of light in a galaxy roughly 848 million light-years away—a region with a supermassive black hole at the center that had been largely quiet until ...
