Sentences with phrase «radiation near a black hole»

Another source of radiation near a black hole is the corona.

Not exact matches

Brilliant outbursts of radiation from near the black hole had spread outward, struck iron atoms in surrounding gas clouds, and then reflected toward Earth, becoming visible here long after the original eruption.

As the black holes drew near in a deepening pit of spacetime, they also churned up that fabric, emitting gravitational radiation (or gravity waves, as scientists often call them).

A gamma ray burst is thought to emerge when jets of hot matter moving at near — light - speed shoot out along the rotational axis of the newborn black hole, beaming radiation into space like a lighthouse.

The ionization increases, the astronomers say, near black holes that are swallowing up matter at a higher rate relative to their mass, which creates more radiation capable of stripping away electrons.

To limit inherent systematic uncertainties, Ghez's group accounted for overlapping light sources when one star passes in front of another or near the black hole itself, where infalling material emits radiation.

In the new study, Charles Hailey, an astrophysicist at Columbia University, and his colleagues scrutinized the past dozen years of data gathered by the Chandra X-ray Observatory, an orbiting craft whose instruments are designed to detect high - energy radiation emitted by the immensely hot material surrounding exploded stars and near black holes.

The observations also showed that radiation from the black hole was consistently near or above the Eddington limit, the point of balance between the force of outward radiation from the hot gases inside and the gravitation force acting inward.
