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 ...

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 ...

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 ...

Scientists based in the U.S., Italy, and Spain, set their sights on a mysterious cosmic duo called PSR J1023+0038, or J1023 for short. The J1023 system is comprised of a rapidly rotating neutron star ...

The research comprises two papers, one published in The Astrophysical Journal in April 2024, and one as yet unpublished that will be submitted to the same journal. The results will be presented at the ...

In the article published today in the Astronomy & Astrophysics journal, new evidence suggests how supermassive black holes, with masses of several billion times that of our Sun, formed so rapidly in ...

Black hole accretion processes remain at the forefront of astrophysical research, offering critical insights into how matter is captured by these extreme objects. Accretion occurs when gas, dust, and ...

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 ...

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 ...

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, ...
