Not exact matches

According to their model, an incoming black hole with at least 20 % of the mass of its partner will knock the main black hole off kilter, no matter how rapidly it spins.
Now Enrico Barausse, also at the University of Maryland in College Park, and his colleagues reckon that such incoming particles needn't strip spinning black holes.
But in 2009, physicists Ted Jacobson and Thomas Sotiriou at the University of Maryland at College Park calculated that, under some circumstances, an incoming particle might cause a spinning black hole to rotate so fast that this horizon is destroyed, allowing light to escape.
«Remarkably, we could also infer that at least one of the two black holes in the binary was spinning
This head - spinning idea is one cosmologist's conclusion based on a modification of Einstein's equations of general relativity that changes our picture of what happens at the core of a black hole.
Most black holes must spin at least a little bit.
LIGO researchers found that the black hole spins were not aligned, and that there's an 80 % probability that at least one of them spun in generally the opposite sense of the orbital motion.
Every gravity field is made of circulating dark matter where the circulation is due to a maximall spinning black hole at the center.
WASHINGTON, D.C. — A furiously blinking x-ray source near the center of the Milky Way has given the best evidence to date that black holes spin, astronomers reported here 30 April at a meeting of the American Physical Society.
These rapidly spinning neutron stars flash regular radio pulses, and in an upcoming issue of The Astrophysical Journal astronomers say that the timing of such pulses could provide a new understanding of the 4 million solar mass black hole at the center of the Milky Way.
At the end of this process, the spins and orbits of both black holes would have become inextricably linked, so each black hole's equator would be aligned with the plane of their shared orbit.
They are powered by supermassive black holes at the centre of galaxies, surrounded by a rapidly spinning disk - like region of gas.
It comes from the spinning space - time around the black hole and in fact it is not very well known, but that energy is there for the taking — up to 29 percent of the so - called rest mass energy of a spinning black hole is extractable — an d original conjecture, which is not, as I say [said], yet established fact, but certainly taken much more seriously than it was at that time — 10 or 15 percent of the rest mass energy of the black hole, about half of the spin energy, is in practice according to our conjecture, is in fact, the power source for these relativistically moving jets.
From the radiative efficiency they were able to calculate the spin of the black hole at the center.
A team led by Dr. Andreas Schulze at the National Astronomical Observatory of Japan investigated the possibility that the spin of the supermassive black hole might play a role in determining if the high - speed jets form.
If the black hole is spinning, it drags on the field, winding it into a tight cone at the rotational poles of the black hole.
GRBs occur when massive, spinning stars collapse to form black holes and spew out jets of gas at nearly the speed of light.
The teams also suspect that the final black hole was spinning at perhaps 100 revolutions per second, although the margin of error on that estimate is large.
Quasars are generally thought to be supermassive black holes at the cores of galaxies, the black hole surrounded by a spinning disk of material being drawn inexorably into the black hole's gravitational maw.
In 2013, researchers determined that one massive black hole measuring more than 2 million miles (3.2 million kilometers) across was spinning at around 84 percent of the speed of light [source: Fazekas].
