- Accretion around black holes: The geometry and spectra
The thin disk is a geometrically thin, optically thick accretion flow, characterized by multi-color blackbody radiation with effective temperatures ranging from 10 5 K to 10 7 K from supermassive black holes to stellar mass black holes
- Light bending and X-ray echoes from behind a supermassive black hole
The innermost regions of accretion disks around black holes are strongly irradiated by X-rays that are emitted from a highly variable, compact corona, in the immediate vicinity of the black hole1–3
- Explanation found for X-ray radiation from black holes
This slowly flowing stream of gas often forms an accretion disk around the black hole, a bright, observable source of X-rays Since the 1970s, attempts have been made to model the radiation from

- Returning radiation in strong gravity around black holes: reverberation . . .
Measured samples of X-ray reverberation lags are shown to be consistent with X-rays returning to the accretion disc in strong gravity Understanding the effects of returning radiation is important in interpreting reverberation observations to probe black holes
- Researchers Unveil Mechanism Behind X-ray Emissions from Black Hole . . .
Insights into the Origins of Radiation The study showed that turbulent plasma naturally produces the type of X-ray radiation observed from accretion disks Additionally, the simulation revealed that plasma around black holes can exist in two distinct equilibrium states, depending on the external radiation field
- Chandra :: Resources :: Black Holes (Illustrations)
1 Accretion Disk Around Black Hole As gas swirls toward a black hole, frictional forces heat the gas to increasingly higher temperatures On the inner edge of the disk, temperatures reach millions of degrees and the gas produces X-rays Note that the inner edge of the disk is white on the right side, and red on the left side This is because the gas on the right side is moving toward the
- Solving the Puzzle of X-Ray Radiation From Black Holes
Since the 1970s, attempts have been made to model the radiation from the accretion flows around the black holes At the time, X-rays were already thought to be generated through the interaction of the local gas and magnetic fields, similar to how the Sun’s surroundings are heated by its magnetic activity via solar flares
- NASA SVS | Black Hole Accretion Disc Energies
A black hole is a massive object whose gravitational field is so intense that nothing - not even light (electromagnetic radiation) — can escape from within its so-called event horizon Accretion disks of hot material encircle many black holes, and this material emits X-rays and other forms of energy Gas closer to the black hole is hotter and emits more energetic radiation Gas at the
