(PhysOrg.com) -- A team of Japanese astrophysicists and space scientists have found a way to more precisely describe where in space a very large, but distant black hole lies. In their paper published in Nature, the team describes how they’ve used data from a large array of radio telescopes spread across the Pacific ocean to measure high energy emissions that are ejected from areas inside the galaxy M87 due to the actions of the massive black hole that lies somewhere near its center.

While it is commonly known that generally suck up everything around them, there is one exception; of radio waves that are thought to form when material that is being sucked in spirals, forming a cone that ejects material as it spins. Sort of like a tornado that sucks up material then spits it out into the air. Only in this case, the jets are all perpendicular to the source. It’s because of these radio jet emissions that we here on Earth are able to find black holes. And though the process by which the jets form is still rather a mystery, scientists are getting closer, and that’s where this new research comes in.

To get a better picture of where the radio waves are actually emanating from inside of relative to the black hole at its center, the team traced the radio jets (using data from the Very Long Baseline Array of radio satellites in the Pacific and complex mathematical models) to near their origin, which then allowed them to better estimate where the black hole actually resides. To their surprise they found that the core of the radio jet appears to be closer to the black hole itself (a fraction of a light year) than had been previously thought.

As with any advance in understanding the cosmos, the results of this latest research while providing new information on how galaxies and black holes work, they also whet the appetite for more. Newer and better radio telescopes still in the planning stages will hopefully give more detail about matter as it is being pulled into a black hole, giving new clues about what is emitted in the process.

Abstract
Powerful radio jets from active galactic nuclei are thought to be powered by the accretion of material onto the supermassive black hole (the ‘central engine’)1, 2. M87 is one of the closest examples of this phenomenon, and the structure of its jet has been probed on a scale of about 100 Schwarzschild radii (Rs, the radius of the event horizon)3. However, the location of the central black hole relative to the jet base (a bright compact radio ‘core’) remains elusive4, 5. Observations of other jets indicate that the central engines are located about 104–106Rs upstream from the radio core6, 7, 8, 9. Here we report radio observations of M87 at six frequencies that allow us to achieve a positional accuracy of about 20 microarcseconds. As the jet base becomes more transparent at higher frequencies, the multifrequency position measurements of the radio core enable us to determine the upstream end of the jet. The data reveal that the central engine of M87 is located within 14–23Rs of the radio core at 43 GHz. This implies that the site of material infall onto the black hole and the eventual origin of the jet reside in the bright compact region seen on the image at 43 GHz.

Sorry, but Black Holes, Big Bang, the AGW model of Earth's climate, and the SSM (Bilderberg) model of stars are utter fiction!

Like the Emperor's new invisible suit!

World leaders and consensus scientists must now face decades of experimental observations and data that they ignored since agreeing to adopt the Bilderberg model [1] of the Sun in 1971.

They are reviewed here [2,3]

I deeply regret the harshness of my comment here. You are not at fault.

I failed to grasp and to communicate that our most cherished values were compromised by political leaders who started using government science for political ends about 40 years ago (1971-2011) .

Eisenhower warned of this danger in 1961, when I was a young graduate student being trained by Professor (Paul) Kazuo Kuroda, formerly of the Imperial University of Tokyo.

Einstein Quote:
Its a shame to create Black Holes even for fiction.

The truth is that no forces of nature can be limitless. There cannot be extreme unlimited conditions of nature that can exist and still be stable, it will blowup sooner or later. Why should a BH singularity if it exists be stable and then regard the BB singularity was not stable? Well that is a double standard for singularities. Any way I have concluded that the force of gravity can be extremely strong but is limited, I call it the G force boundary, which will safely eliminate the possibility of the existence of singularities of any kind.
Black holes should outshine any star, but we dont see such objects, because they dont exist!
A simple test to detect black holes( if they exist) is to base it on the good old concept of the bending of star light around a massive body. And in this case if that massive body is a BH we should see a halo of back ground stars projected all around the alleged BH position because o

Btw, Einstein also concluded that Quantum Mechanics could not be real. "God doesn't play dice" he said in respect to the probability distribution of the electrons around an atom. But still it is so.

Einstein was a genuine genius but not always right. He had problems with his own theories. He had a strong believe of what was true, like physics being subject to the same laws everywhere in the universe and he proved this!
Unfortunately, his formula's also pointed out singularities of gravity so strong that they would be able to catch light (black holes). He also tried to rewrite the formula's to find his error (because he could not imagine this to be true) but he never succeeded.

Perhaps he was still right?

But on a serious note, can you explain in common english what mechanism you believe to be responsible for the appearence of jets at what commenly is believed to be a black hole (I know you will probably explain that it is neutron repulsion but explain the mechanism in simple and plain english).

Neutron repulsion is probably the driving force. But i do not know the mechanism of creating the jets.

This topic has been discussed on the "Neutron Repulsion Discussion Group."

I suspect that the answer may be found in the similarity between nuclei of stars and nuclei of atoms.

I think we can both agree that gravity around a BH/Neutron star is immens and this will attract a lot of mass. Since both are very fast spinning, it is likely that also huge magnetic fields are created. This field can (and if present it certainly will) act as an accelerator. Only thing needed for such a field is that the mass inside (BH/Neutron Star) has a net magnetic value.

If I am not mistaken, the jets tend to broaden and at the end go into opposite positions what would certainly add to to theory that magnetic fields are created.

If the star, or the mass that is crushed in the accretion disk created enough X-rays, etc, a magnetic field component is always present. This would mean that it is not "really relevant" what is inside for creating the jets. The object inside could focus the magnetic field though.

Omatumr, what are your thought regarding this?

Isn't a black hole simply a huge amount of mass with an event horizon? I don't believe a singularity is required to form an event horizon, right? If we assume that a singularity is not possible (after formulating a quantum theory of gravity),what would the inside of a black hole contain? If you look at the most extreme conditions we can think of, shouldn't the interior of the black hole consist of some kind of stable quark gluon plasma (again, assume that a singularity is not possible)?

Also a thought, only supported by imagination ;-)
Im familiar with a lot of theories but does anyone know whether energy itself can sustain a form of gravity? If so, a black hole could simply be the most compact form of mass, being solely energy. Friction due to gravity could be so high that the interior is composed of pure energy.

Dear Oliver.

As the article states is that the universe is expanding due to the solar radiation of particles. I presume this mechanism will be spherically distributed.

My question however was concerning the jets around black holes which can hardly be described as "spherical expansion"...

So basically, I don't really know what the article had to contribute to my question. Could you please elaborate?

Some think the jets are evidence of a z-pinched plasma.

But if we use your own theory of Neutron Repulsion then we MUST come to the conclusion that there are no Neutron Stars.

Can you explain how Neutron Stars form when Black Holes can't due to Neutron Repulsion?

Not answering shows that you don't have an answer for this very important question.

IF Black Holes are impossible due to Neutron Repulsion
THEN Neutron Stars MUST also be impossible

Please explain this contradiction in your claims.
