So far only weak magnetic fields have been discovered and they are also at a great distance from the black hole - at least a few light years. In the current study, astronomers from the Klammers University of Technology and the Onsla Observatory in Sweden were able to observe using Alma signals directly belonging to strong magnetic fields very close to the event horizon of a massive black hole in a distant galaxy called PKS 1830-211.
Astronomers have uncovered an enormous magnetic field - much larger than any magnetic field discovered so far in the core of a galaxy, very close to the event horizon of the supermassive black hole.
The Alma Atacama Large Millimeter/submillimeter Array (ALMA) telescope has revealed an enormous magnetic field, beyond all those discovered so far, in the core of a galaxy, very close to the event horizon of a supermassive black hole.
The new observations help astronomers understand the structure and composition of supermassive black holes at the centers of galaxies and the twin plasma jets they emit from their poles. The findings were published in the April 17 issue of the journal "Science".
Supermassive black holes whose mass reaches billions of times the mass of the Sun are at the core of almost all galaxies in the universe. These black holes accelerate enormous amounts of matter into the disk surrounding them. While most of the matter is fed into the black hole, another part of it can escape just before capture and fly into space at the speed of light as part of a plasma jet. However, it was not known until now how the process is carried out, although it was clear that it must involve magnetic fields operating very close to the event horizon that help matter escape from the powerful jaws of darkness.
So far only weak magnetic fields have been discovered and they are also at a great distance from the black hole - at least a few light years. In the current study, astronomers from the Klammers University of Technology and the Onsla Observatory in Sweden were able to observe using Alma signals directly belonging to strong magnetic fields very close to the event horizon of a massive black hole in a distant galaxy called PKS 1830-211. These magnetic fields are located exactly where matter is suddenly accelerated out of the black hole in the form of a jet.
The team members measured the strength of the magnetic field by investigating the way light is polarized as it moves away from the black hole. "Polarization is an important property of light that is also used by us in our everyday life. For example in sunglasses or XNUMXD glasses in the cinema" says Ivan Marti-Vidal, the lead researcher. "When it occurs naturally, the polarization can be used to measure magnetic fields, because light changes its polarization when it passes through a magnetized medium. In this case, the light we discovered with Alma moves through matter very close to the black hole, a place full of strongly magnetized plasma."
The astronomers used a new analysis technique they developed for the Alma data and found that the direction of polarization of the radiation coming from the center of PKS 1830-211 had rotated. These are the shortest waves used so far in this type of research, which made it possible to observe areas very close to the center of the black hole.
"We found clear signals for rotation caused by strong polarization thousands of times the strongest polarization we found in the universe" said Sebastian Müller, a partner in the study. "Our discovery is a big step in terms of frequency of observations thanks to the use of ALMA, and in terms of research from the black hole where magnetic fields were observed - orders of magnitude of several light days from the event horizon. These findings and future studies will allow us to understand what is really happening in the immediate vicinity of the supermassive black hole at the center of the galaxy.

Chaim + Keshit you are retarded! Learn to read! Why who are you anyway!

May I know what the branch is? What you are doing at best is mixed Jerusalem. If they opened a department for gibberish sciences, you would receive a doctorate with high honors.

Someone calls the circus director and tells him that he has a great show for him: he can explain Maxwell's theory to the audience.
Go away, says the director, this is a circus, not a university.
But I can also explain Einstein's theory - the aforementioned insists.
Sir, the director gets angry, call the Technion and leave me alone.
Wait, wait, don't hang up, I can also explain Newton's theory...
The manager gets angry and hangs up the phone.
The one on the other side mumbles: Oh, what a fool I am, I forgot to tell him that I'm even a horse...
We will not agree that Sesum Eskensi will enter the Selno website, will we?
Asaf,
If you continue to "deploy" your line of thought
Let's say you are Russian. drunk
that measured the horizon of events
The bouncer comes and puts an explosion in your head.
And on this Maxwell said:
One horse enters the beck and orders a beer
The bartender asks him: "Shall I add you a straw?"
"Yes", replies the horse, "add me a lot of straw".
post Scriptum.

We are open to new information, but it's better if you open it yourself and don't throw us comments in a row. Response style:
"It is possible that the dark matter is radioactive fallout: i.e. radioactive dust - which can be measured." End quote is not a response we can take seriously. After all, dark matter is not a bully. And if it was radioactive, then it would have been discovered a long time ago. Hence the name "dark matter". If you keep responding like this we will just ignore you.
Good Day

It is better for screenwriters to test your theories - maybe they will find interest in them 🙂
Assaf our brother, why curses? Is it not possible to transfer sections with ease? Why take everything with a heavy head. Why not Sotul, Shanti, Ananim...
Where, where is this Ashkenazi you were talking about. Bring him here now, Israel is mowing him down.
My theory is laid out here, with physicists interested in testing it I would be happy. Greetings, Asaf Bar.
Israel Shafiar, I am disgusted by snobs like you. If I were not an Ashkenazi I would think that all Ashkenazim are full of themselves like you.
And the situation is doubly worse if instead of atomic bombs they use backup bombs.
Since a black hole was created in a violent super nova explosion, the desperate activity of the material to fill the void fails. Because due to the effort it collapses and ends in a nuclear explosion, which further expands the black hole!
It could be that the dark matter is radioactive fallout: i.e. radioactive dust - which can be measured.
Massive activity takes place at the entrance of the black hole, and a traffic jam is created. Let's say I'm an asteroid and I'm drifting into a vacuum. Right at the entrance, I get an atomic bomb in my face right before I also become such a bomb
The main problem is: when the light comes in, where does the darkness go?
Something to think about.
Since it is easier for light to move in a vacuum than in the middle of space. It seems that the light is attracted to the black hole. In my opinion, a black hole = empty (vacuum). Hence the hypothesis that, as in a laser, free electrons (operates in a vacuum). Likewise, light will operate inside the black hole.
Is the behavior of light in the black hole similar to free electron lasers? Maybe someone from Ariel University will give an answer?
And maybe things never happened?
With indeed dark matter is not attracted to black holes. Perhaps it serves as a brake on the growth of black holes. Perhaps when all matter is converted into dark matter, there will be another big bang. So much for theories, I will be happy with someone disproving all my theories. Thanks in advance.
And perhaps, massive jets of Kernix and dark matter that nephilite from massive black holes, causing the universe to expand. There is an ambivalent situation here, a dilution of material that is spread over more space!
And perhaps the vacuum created in the field (the surface) is what causes matter and light to be drawn in, i.e. as if there were water looking for a low place to flow and fill. The speed of movement, and the friction cause the atoms to melt. And the mechanical phenomena of an electromagnetic pulse, and the X-rays.
To Moshe, nuclear activity creates an electromagnetic pulse - this is known from atomic bombs. Since in a black hole the atoms are compressed under pressure, then it is likely that this is the source of the electromagnetic fields.
Gravity that turns into the electromagnetic force around a black hole?
