Sentences with phrase «as black hole jets»

MHD simulations, the magnetism of electrically conducting fluids such as black hole jets, add a layer of understanding but are notoriously difficult for even the fastest supercomputers.

We speculate that when the black hole was being rapidly force - fed by its companion orbiting star, it reacted violently by spewing out some of the material as a fast - moving jet.

The most powerful jets, called quasars, arise when black holes weighing as much as billions of suns fling infalling matter and energy back out into the galaxy, heating up loads of dust and gas and creating blinding beams of energy.

Jets are narrow streams of gas that emergefrom the cores of some galaxies, travel at more than 99 percent thespeed of light, and penetrate as much as several million light - yearsinto intergalactic space before fanning out into broad, luminous lobes.How might a black - hole whirlpool generate such a pair of waterspouts?Swirling bundles of magnetic field lines, flinging particles outwardfrom the poles of the hole, provide a natural explanation.

The idea that neutron stars can produce x-ray jets as powerful as those created by black holes is «a pretty big deal» that challenges some of the current models of the phenomena, says astrophysicist Rob Fender of the University of Southampton in the U.K..

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.

It is this twisted field that accelerates particles away from the black hole as jets and, in the process, extracts energy from the rotation of the black hole.

He says existing models of the jets assume they require certain properties unique to black holes, such as event horizons.

Minkel: So, the jets that you said were sort of a generic feature coming out of, I think, you said proto - planetary disks and as well as around black holes — so, what's the mystery with those, are they, especially powerful or impressive in some way?

Some possible scenarios: incredibly massive black holes erupting in jets of matter, galaxies colliding or star - producing factories known as starburst galaxies.

A small fraction of supermassive black holes — the ginormous ones that lurk at the centers of galaxies — fire off light - speed jets of particles as they snack.

A rapidly rotating but unseen companion star — one that collapsed as a neutron star or black hole at the time of the supernova — could have produced these jets.

In rare cases, black hole births are even more spectacular, with the star firing out powerful jets of high - energy radiation as it dies — a phenomenon known as a gamma - ray burst.

As a result of this massive «meal» the black hole begins to launch a powerful jet that we can detect with radio telescopes.

The discovery is the first time scientists have been able to see both a disk of material falling into a black hole, known as an accretion disk, and a jet in a system of this kind.

As matter is broken down around a black hole, jets of electrons are launched by the magnetic field from either pole of the black hole at almost the speed of light.

Among them, Active Galactic Nuclei (AGN) represents a type of supermassive black hole which are gulping down surrounding gas very actively and emitting some amount of gas as a high - speed gas flow (jet).

The black hole has a mass of about 2 billion solar masses, and as matter falls into the black hole it is concentrated by the intense magnetic fields around the black hole and some of it is propelled outwards to form the jet.

Researchers think these bubbles drag trails of relatively cooler gas (about 1 million degrees), and as the bubbles detach from the jets and drift farther out into the galaxy, the cooler gas trails become even cooler, becoming extremely cold (just slight above absolute zero), and rain back on the black hole as fuel for star formation.

Cosmic jets, most astronomers believe, arise when a massive object, such as a neutron star or a black hole, draws in material.

As the distance to that galaxy is only 70 Megaparsec or 230 million light years, we are able to examine the jet structure with an unprecedented accuracy of only a few hundred black hole radii or 12 light days», concludes Professor Anton Zensus, director at the Max Planck Institute for Radio Astronomy in Bonn, Germany and head of its VLBI research department, a co-author of the paper.

Polarimetry is an important method to investigate magnetic fields in the Universe and astronomers eager to use ALMA for unveiling magnetic mysteries, such as the launching mechanism of high energy jets from supermassive black holes.

This ultra-powerful field becomes better organized and forms two outwardly directed funnels along the new black hole's rotational axis, which then creates the two bi-polar jets of particles moving near the speed of light that are detected as a short GRB (NASA news release; Seil Collins, New Scientist, April 13, 2011; and Rezzolla et al, 2011; and more discussion and images from Bruno Giacomazzo's presentation).
