Sentences with phrase «hole spin»
The phrase "hole spin" refers to the tiny spinning motion of a hole, which is a concept in physics. It helps scientists understand the behavior of particles at a very small scale. Full definition

«This contrasts with the recent X-ray determinations of (close to) maximal black hole spin in other [similar galaxies] based on relativistic smearing of the iron profile,» the researchers wrote in the study, which was published online today (July 29) in the journal Monthly Notices of the Royal Astronomical Society.
It represents a giant black hole spinning at nearly the speed of light, the space - time around it twisted like a whirlpool, and the fluorescent iron atoms that trace that fantastic motion cast like leaves on swirling water.
And so, like a merry - go - round that goes around faster and faster with every additional push given to it along its rotational direction, the black hole spun faster and faster with time.
Maity was an author of the article, «Black hole spin dependence of general relativistic multi-transonic accretion close to the horizon,» which was published online last December in the journal New Astronomy and in print in the journal's May issue.
The highest - energy light arises from the center of a crescent - shaped region on the side of the black hole spinning toward us.
This study enables astronomers to understand how quickly the jet direction is changing, which reveals information about the black hole spin as well as the orientation and size of the rotating disk and other difficult - to - measure properties of black hole accretion.
That graph, he and his colleagues claim, says it all if you read it right: a giantblack hole spinning at nearly the speed of light, the space - time aroundit twisted up like a whirlpool, and the fluorescent iron atoms thattrace that fantastic motion cast like leaves on swirling water.
«Black hole spin cranks - up radio volume.»
«This makes the black hole spin faster — a bit like an ice skater doing a pirouette.»
«Some supermassive black holes spin at more than 90 % of the speed of light, which suggests that they gained their mass through major galactic mergers.»
Data from these waves will test Einstein's predictions about how fast black holes spin and exactly what happens when they smash into neutron stars and into each other.
One theory is that it must be spinning very slowly — the slower a black hole spins, the weaker its repulsive burps may be, and the longer it can gorge uninterrupted.
There is, however, also the chance that both possibilities are true — that there are instances of black holes spinning slowly in the field and instances of black holes spinning rapidly in a dense environment.
One of the weirdest implications of Einstein's general relativity theory is that as a black hole spins, it pulls space - time along.
Black holes spin.
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.
The faster the black hole spins, the larger its ergosphere becomes, which allows high - energy collisions further from the event horizon.

Anatomy of a Black Hole One of the weirdest implications of Einstein's general relativity theory is that as a black hole spins, itpulls space - time (represented above by green grid lines) along for thetwisty ride.
So although evidence is mounting that black hole spin is powering jets, astrophysicists may have to wait until they can measure the spin of a supermassive black hole before they can nail it.
Fabian says he still has a «slight reservation» about the assertion that the results prove the role of black hole spin.
