This newly expanded and thoroughly updated third edition examines accretion as a source of energy in both binary star systems containing compact objects, and in active galactic nuclei. Assuming a ...

Stellar-mass and supermassive black hole coronas have some similarities, and this is great news for black hole physicists.

From the discovery of gravity to the first mission to defend Earth from an asteroid, here are the most important physics ...

The latest X-ray observatory found a warped black hole disk and a supernova spewing iron — and it’s just getting started ...

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 ...

XRISM is transforming our understanding of supermassive black holes and their galactic neighborhoods, providing ...

Astronomers from Italy and Chile have investigated an accreted stellar stream named Icarus in the Milky Way's disk. Results ...

One of the key components for the evolution of life as we know it is the presence of “volatiles”: elements and compounds that ...

Gas swirls around a black hole due to its intense gravity, forming an accretion disk. These accretion disks, being among the most efficient energy conversion mechanisms in the universe ...
