Scientists may have found the smallest black hole yet by listening to its X-ray "heartbeat." The black hole, if it truly exists, would weigh less than three times the Slide 18 of 48 Slide 18 of 48

This image shows the distribution of gas density (colors from blue for low density to red for high density) in a black hole accretion disk simulation. A new technique to study the bright disc of matter surrounding a distant black hole is as precise as spotting individual grains of sand on the surface of the moon. Abstract: This review covers the main aspects of black hole accretion disk theory. We begin with the view that one of the main goals of the theory is to better An international team of astronomers has used a new technique to study the bright disc of matter surrounding a faraway black hole.

The existence of the radius of marginal stability means that accretion flows around black holes invariably undergo a transition from a MHD turbulent disk-like flow to team of researchers working at the Astrophysical Institute of the Canary Islands has found evidence of a previously unknown structure in the accretion

Researchers find 'structure' in black hole accretion disk Simulation of the X-ray binary system Swift J1357.2-0933. In this view, the dips produced by the vertical A dipole magnetic field topology showing gas densities in a black hole accretion disk. Dark blue indicates low gas density and dark red indicates high gas density.
