Sentences with phrase «gas near the black hole»

That was consistent with a quasar, but dust blocked the definitive quasar signature of spectral lines emitted by gas near the black hole.

To find out what's going on, Daniel Wang at the University of Massachusetts Amherst and his colleagues used NASA's Chandra X-ray Observatory to measure the temperature and abundance of gas near the black hole.

Instead, the X-ray data show the gas near the black hole likely originates from winds produced by a disk - shaped distribution of young massive stars.

Not exact matches

These observations help clarify the origin of the powerful jet of gas streaming from the galaxy's center at a high fraction of the speed of light: it is likely driven by the swirling matter near the black hole's boundary.»

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.

Blobs of gas roughly the mass of Jupiter (several illustrated) could form near the black hole at the center of the Milky Way and shoot into intergalactic space.

In the simulation, Bonnell and colleague Ken Rice of the University of Edinburgh placed a cloud of gas 10 light years away from a black hole on a path that would take it near the edge of the black hole.

Their tendency would be to cluster near the centre of galaxies, making them more likely to pass near the supermassive black holes that sit there and run into the accretion discs of gas that surround them.

Assuming this is the orbital period of hot gas revolving near the black hole, the astronomers deduce that the monster weighs 450,000 to 5 million times more than the sun, agreeing with previous estimates and making the black hole comparable to the 4 - million - solar - mass one at the Milky Way's center — but located in a galaxy 3.9 billion light - years away.

Previously, astronomers have used x-ray telescopes to observe strong winds very near the massive black holes at galactic centers (artist's concept, inset) and infrared wavelengths to detect the vast outflows of cool gas (bluish haze in artist's concept, main image) from such galaxies as a whole, but they've never done so in the same galaxy.

Scientists can also do reverberation mapping, which uses X-ray telescopes to look for time differences between emissions from various locations near the black hole to understand the orbits of gas and photons around the black hole.

Light from near a baby black hole still enshrouded in a gas cloud would emerge in infrared wavelengths, so redness is a good indicator that you've found one.

Now, professional researchers and Galaxy Zoo volunteers working together have found 19 similar objects — glowing gas clouds near galaxies whose black holes appear quiet but probably blasted the clouds in the past.

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.

Astronomers find evidence of enormous black hole one hundred thousand times more massive than the sun in a gas cloud near the galaxy's centre.

Most X-rays are emitted by pockets of hot gases found between galaxies and near black holes.
