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 ...

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 ...

Some stars never really die. Pulsars are the undead magnetized cores of massive stars that have met their end in a supernova. They rotate furiously, spewing jets of electromagnetic radiation from ...

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.

Astronomers are uncovering the secrets of quasi-periodic oscillations (QPOs) — subtle, rhythmic X-ray pulses from black hole systems. Using cutting-edge telescopes and advanced analysis methods, ...

An international scientific team has revealed for the first time the magnetic field transport processes in the accretion flow of a black hole and the formation of a "MAD"—a magnetically arrested ...

Supermassive black holes lie in the centers of all large galaxies. And a group of astronomers including researchers from MIT and NASA have, for the first time, measured how fast one of these behemoths ...
