Sentences with phrase «black hole accretion»

But Saint Andrews's Forgan thinks Batygin's approach could be particularly useful for modeling black hole accretion disks that are warped by companion stars.

This study enables astronomers to understand how quickly the jet direction is changing, which reveals information about the black hole spin as well as the orientation and size of the rotating disk and other difficult - to - measure properties of black hole accretion.

«In fact, the energy and timescale of the gamma - ray emission is a better match to some types of supernovae, or to some of the supermassive black hole accretion events that Swift has seen,» Fox said.

Black hole accretion powers its jets.

In doing so, the researchers hope to create a model that better predicts the emission of radiation from black hole accretion at the galactic center, bringing the predictions in line with astrophysical observations made using NASA's Chandra X-ray observatory.

The mechanisms behind black hole accretion are poorly understood, but the researchers suggest that this example may just have been an «early bloomer» that had an extremely active youth, only to settle down as a «regular» supermassive black hole in a large elliptical galaxy.

The resulting disk has a series of vibrational «modes,» rather like resonances in a tuning fork, that might be excited by small disturbances — think of a planet - forming stellar disk nudged by a passing star or of a black hole accretion disk in which material is falling into the center unevenly.

«If there are many axion stars in the centres, we expect that some of them collide with the black hole accretion disc,» says Iwazaki.

And indeed, David Spergel, a Princeton University astrophysicist who did not contribute to the study, explains that black hole accretion and starbursts can be related.

Although the central black hole is millions of times smaller than the jet, black hole accretion is the only known physical mechanism powerful enough to launch such a jet.
