Sentences with phrase «such black holes»

But theorists struggle to explain how such black holes could form pairs.
Before this signal, the very existence of such black hole binaries was an open question.
Before the signal came in, the very existence of such black hole binaries was contested.
Because such black holes are most likely to exist at the cores of galaxies, a close enough look at a quasar should usually reveal the host around it.
If the new model is correct, then such black hole mergers may occur as frequently as once a year somewhere in the Universe.
It's more than 35,000 light years from the galaxy's centre, where such black holes usually live, and hurtling further out at 2000 kilometres per second.
The first such black hole to be observed was Cygnus X-1, and there are now a number of well - measured X-ray binaries with black holes of...
There maybe millions of such black holes floating around our own galaxy, eachfive or 10 times as massive as our sun and roughly 50 miles around, each spinning more or less furiously — once a millisecond or so would bepossible.
Astronomers have long predicted the presence of such black holes at the center of the galaxy, which they said could number in the thousands.
Such black holes in the stellar and planetary configurations have black holes of the weaker varieties unlike galactic centered black holes.
First, because such a black hole would tug the star to and fro in the sky, it would create an easily detectable wobble — a wobble that Boyajian's team looked for and did not detect.
Such black holes should each weigh 10 to 20 times more than our sun.
Physicists are reasonably sure that no such black holes could escape and consume Earth.
That is of interest because there are competing theories about what would happen to such black holes.
Such black holes are possibly responsible for the gravitational wave events observed by the Laser Interferometer Gravitational - Wave Observatory.
Researchers who have measured the spin of a supermassive black hole in a quasar — the shining core of a distant galaxy — 6.1 billion light - years away say that such black holes have likely grown through mergers between their host galaxies and other galaxies.
Such a black hole (and its hypothetical disk) would have escaped Boyajian's efforts at high - resolution imaging because it would emit no light itself.
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.
But this slow process can't explain the problem of supermassive black holes existing in the early universe — such black holes would have formed less than one billion years after the Big Bang.
Moreover, statistical estimates do suggest that such a black hole could have passed in front of at least one of the 150,000 stars monitored by Kepler during the four years of its survey.
Now, a team of researchers using the ASTE Telescope in Chile and the 45 - meter Radio Telescope at Japan's Nobeyama Radio Observatory, has, quite serendipitously, discovered one such black hole — one that is estimated to be roughly 36 times as massive as the sun.
However, such black holes (those with close companions) are very rare.
