Sentences with phrase «such large black holes»

We infer this based on our current understanding of massive - star winds (which drive mass loss) and their dependence on metallicity: had the environment been high - metallicity, it is unlikely that such large black holes would have been able to form.

Such large black holes are already known to have strong magnetic fields and to make polarized light rotate.

Merritt and Ekers project that a typical large galaxy will undergo a black - hole - tilting crash once every billion years — enough for one such event to pop off somewhere in the universe each year.

We once thought that dark matter might be made up of large objects such as black holes or exotic types of faint stars — neutron stars or white dwarfs — that are nearly invisible to our telescopes.

«It is the first time that we have seen outflowing cold gas moving at these large speeds at such large distances from the supermassive black hole,» said Claudia Cicone, a PhD student at Cambridge's Cavendish Laboratory and Kavli Institute for Cosmology, and lead author on the first of the two papers.

The team expects to disentangle the two possible scenarios and find more solid evidence for a black hole in the Bullet with higher resolution observations using a radio interferometer, such as the Atacama Large Millimeter / submillimeter Array (ALMA).

Imagine that such a black hole is orbited by a wide, cold disk of material — like the rings of Saturn but larger than our entire solar system — and that this disk possesses an almost transparent outer region and a denser inner region.

The universe is currently described using two distinct frameworks: gravity for larger objects such as planets and black holes, and quantum mechanics for the tiny world of bosons and quarks.

Residing in the dwarf galaxy IC 10, 1.8 million light - years away in the constellation Cassiopeia, the new black hole puzzles researchers because it is thought that the kind of star that would give birth to it would not have retained enough mass to produce such a large object.

The supermassive black hole found in NGC 1600 is one of the first successes of the project, proving the value of a systematic search of the night sky rather than looking only in dense areas like those occupied by large clusters of galaxies, such as the Coma and Virgo clusters.

Astronomers have known for some 10 years that nearly every large galaxy contains at its core an immense black hole — an object having such intense gravity that even light can not escape.

Reinhard Genzel will discuss measurements over the last two decades, employing adaptive optics imaging and spectroscopy on large ground - based telescopes that prove the existence of such a massive black hole in the center of our Milky Way, beyond any reasonable doubt.

«This is remarkable that the supermassive black hole is able to impact stars forming at such large distances,» says Wright.

Based on their observations, they have concluded that the rate of a TDE occurring increases «dramatically» when two galaxies are colliding, most likely due to the fact that such events cause a large number of stars to be formed near the central supermassive black holes of the merging systems.

Or in the case of a 2015 result using Hubble observations of large elliptical galaxies, jets from supermassive black holes may regulate star formation in such a way that it keeps going, albeit at a slower rate.
