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.

The primary growth pathway of both stellar mass black holes (such as those found in X-ray binary systems), and supermassive black holes (found in active galactic nuclei) is through the accretion of ...

Abstract: Understanding the plasma physics of accretion disks and coronae around black holes is crucial for interpreting the radiation observed from these systems. However, these plasmas span several ...

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 ...

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

Ultraluminous X-ray sources (ULXs) represent some of the most energetically extreme phenomena in neighbouring galaxies, emitting X‐ray luminosities that can far exceed the Eddington limit. Long ...

Astronomers have discovered a previously unknown link between the way young stars grow and the way black holes and other exotic space objects feed from their surroundings. The study, ...

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 ...

Could one cosmic event outshine 10 trillion suns? Astronomers have now observed just that a record-breaking flare from a supermassive black hole, fueled by the cataclysmic destruction of a massive ...
