Sentences with phrase «cloud by a black hole»

A cosmic phenomenon on a colossal scale, resulting from the acceleration of a gas cloud by a black hole and its reacceleration by the shock waves from the merging of two galaxy clusters, has been observed, described and interpreted by an international collaboration of astronomers that included three Brazilians: Felipe Andrade - Santos, Vinicius Moris Placco, and Rafael Miloni Santucci.

In the new observations, certain wavelengths seem to be absorbed by fast - moving gas clouds, presumably debris from a doomed star: relatively cool gas laden with ionized carbon and silicon, flowing away from the black hole with a velocity of some 6000 kilometers per second.
Now a team led by Fabio Pacucci at Scuola Normale Superiore in Pisa, Italy, thinks it has found two examples of the latter: baby black holes that formed directly from a collapsing gas cloud without becoming a star first.
The researchers conclude that galaxies may thus be formed by clouds of gas that are bombarded by streams of matter and energy from black holes — which are building their own homes.
Astronomers believe it was shot from the Large Magellanic Cloud by an as - yet - unseen black hole.

This cloud is now making its closest approach and new VLT observations show that it is being grossly stretched by the black hole's extreme gravitational field.
The clouds were probably energised by nearby monster black holes that had blasted them with intense radiation.
New observations from ESO's Very Large Telescope show for the first time a gas cloud being ripped apart by the supermassive black hole at the centre of the galaxy.
According to the researchers, there are two possible scenarios in which such a cloud could have been created — the first one that involves the expanding gas shell of the supernova remnant passing by a static black hole, and the other wherein a fast - moving black hole plunges through a cloud of dense gas that is then dragged along by the former's strong gravity.
See images of new observations from ESO's Very Large Telescope showing a gas cloud ripped apart by the supermassive black hole at the center of our galaxy, the Milky Way.
Astronomers using the National Science Foundation's Very Long Baseline Array (VLBA) of radio telescopes have discovered a cloud of gas apparently being struck by a jet of ultrafast particles powered by the energy of a supermassive black hole at the core of a galaxy 450 million light - years away.

Using data from three of NASA's Great Observatories (the Hubble Space Telescope, Chandra X-ray Observatory, and Spitzer Space Telescope), scientists have found the best evidence to date that supermassive black holes in the early universe were produced by the direct collapse of a gas cloud.
An image of clouds accelerating due to gravitational scattering caused by the intermediate - mass black hole.
SDSS studies have probed the dark matter environments of quasars through clustering measurements, revealed populations of quasars whose central engines are hidden by obscuring dust, captured changes in quasar spectra that show clouds moving in the gravitational grip of the central black hole, and allowed a comprehensive census of the much fainter accreting black holes (active galactic nuclei, or AGN) in present - day galaxies.
