Twin jets pinpoint the heart of an active galaxy

An international team of astronomers has measured the magnetic field in the vicinity of a supermassive black hole. A bright and compact feature of only 2 light days in size was directly observed by a world-wide ensemble of millimeter-wave radio telescopes in the heart of the active galaxy NGC 1052. The observations yield a magnetic field value at the event horizon of the central black hole between 0.02 and 8.3 Tesla. The team, led by the PhD student Anne-Kathrin Baczko, believes that such a large magnetic field provides enough magnetic energy to power the strong relativistic jets in active galaxies. The results are published in the present issue of Astronomy & Astrophysics.

The technique used to investigate the inner details of NGC 1052 is known as very-long-baseline interferometry, and has the potential to locate compact jet cores at sizes close to the event horizon of the powering black hole. The black hole itself remains invisible. Usually, the black hole position can only be inferred indirectly by tracking the wavelength-dependent jet-core position, which converges to the jet base at zero wavelength. The unknown offset from the jet base and the black hole makes it difficult to measure fundamental physical properties in most galaxies. The striking symmetry observed in the reported observations between both jets in NGC1052 allows the astronomers to locate the true center of activitiy inside the central feature, which makes, with the exception of our Galactic Centre, the most precisely known location of a super massive black hole in the universe. Anne-Kathrin Baczko, who performed this work at the Universities of Erlangen-Nürnberg and Würzburg and at the Max-Planck-Institut für Radioastronomie, says: "NGC 1052 is a true key source, since it pinpoints directly and unambiguously the position of a supermassive black hole in the nearby universe."

NGC 1052 is an elliptical galaxy in a distance of approximately 60 million light years in the direction of the constellation Cetus (the Whale).

The by the supermassive black hole was determined measuring the compactness and the brightness of the central region of the elliptical galaxy NGC 1052. This feature is as compact as 57 microarcseconds in diameter, equivalent to the size of a DVD on the surface of the moon. This amazing resolution was obtained by the Global mm-VLBI Array, a network of radio telescopes in Europe, the USA, and East Asia, that is managed by the Max-Planck-Institut für Radioastronomie. "It yields unprecedented image sharpness, and is soon to be applied to get scales in nearby objects", says Eduardo Ros from the MPI für Radioastronomie and collaborator in the project.

The unique powerful twin jets at a close distance, similar to the well-known active galaxy M 87, puts NGC 1052 in the pole position for future observations of nearby powerful galaxies in the oncoming era opened by the addition of ALMA, the Atacama Large Millimetre array, to the world-wide networks in radio interferometry.

The observation may help solving the long-standing mystery of how the powerful relativistic jets are formed, that can be seen in many . The result has important astrophysical implications, since we see that jets can be driven by the extraction of magnetic energy from a rapidly rotating .

They have the structure correct, but the mechanism wrong. The image shows a classic flux tube pinch, but the jets are in reality the regions where particles are glowing due to acceleration, synchrotron radiation, TOWARDS the supposed BH, which is really a vacuum arc at the point where the longitudinal magnetic field tension creates a gap in the flux tube, and the formation of a hard gamma ray source. Gamma-gamma physics models can then be used to explain the matter being created and the magnetic fields observed.
Studies of such jets, as with M87, have not had the temporal resolution to determine a flow direction, and just because they look like jets does not mean they are.

The theme we can do a simple.
Fast the rotating or elliptical galaxy (M 87, NGC 1052, M 32, M49, 59, 60, etc., of the total number of galaxies make up 30%), have the jets and there is a point (Quasars are also elliptical galaxies).

Jets is not tied to a black hole, because 70% of galaxies do not have jets. Jets is tied for the speed of rotation of galaxies or the cyclone in the center of the galaxy.

OK. Most of your post is pure nonsense, but you make a claim/prediction (like good scientists should). You say:

Wager? Unless you can post a picture of a Black Hole it's a hands down win for wduckss. Maybe you can talk Schneibo into posting his pics of BHs?

Oh, don't bother with challenging me on that wager, I don't need anymore money.

........coming from someone who has already made it clear in this chatroom that "Mass & Energy are not EQUAL".

Asstrophysics needs to keep up the charade of this narrative, or poof.......there goes the psycho-babble theory of BHs. The concept that infinite gravity wells can exist on the surface of a finite stellar mass is the most cockamamie unscientific narrative ever conceived, you know this must be the case because who comes here most frequently to defend it?

Mass & Energy are not EQUAL

In physics scrawled on Cartoon blackboards, maybe that's true. Maybe you really are Homer Simpson, living in a cartoon world.

But in real science, in real, actual physics, that statement is only true under one special condition: that the particle, or system of particles, under consideration is measured in a reference frame where it is at rest. In any other reference frame, the energy of its motion must also be added to the energy of its mass. (specifically: it's added in quadrature to the mass, like the pythagorean theorem kind of equation).

Hey Maggie, I do have it figured out & so did Albert Einstein when he warned Schwarzschild about the predicament he would encounter with his Black Hole Math, that INFINITE GRAVITY WELLS cannot exist at the surface of any FINITE STELLAR MASS.

Such a cockamamie concept as Schwarzschil's Black Hole Math totally violates the MASS/ENERGY EQUIVALENCE PRINCIPLE of Special Relativity, that INFORMATION CANNOT BE LOST..........which I know is a tough concept for Asstro-physicists to follow but not so much for those of us who have Nuclear Physics Sciences as the hearts & souls of our professional endeavors, and has become an issue Hawking is trying to straighten out.

WHOA there... We've already established, you have nothing at all to do with the Nuclear Physics community.

I think it's in exceedingly poor taste for one educated group to look down upon another educated group as if they're 'worse,' so I preface my next comments with my own distaste for them. I'm a nuclear physicist. As in went to graduate school in nuclear physics and did research in nuclear physics and so on. You claim to be a nuclear 'engineer.' Fine, even if we're both pretending we accept each other's online credential claims, your comments on what the "nuclear physics" community has to say about things are absolutely disconnected with anything I've ever seen in the nuclear physics community. Maybe it's because you're only an engineer, and are just cranking bolts at a power plant, but you know nothing of actual physics (evidence example 12837: "INFINITE GRAVITY WELLS," a phrase with 0 scientific meaning)
