Telescopes around the world have teamed up to take amazing pictures like never before Black hole M87 * It explodes at 99 percent the speed of light in space.
The event is the same popular black hole captured by the Horizon telescope and released in 2019.
That first release was an amazing achievement. It took many years of work, and radio telescopes spread all over the world, combining their observations and showing a part of space. Not larger than the solar system 55 million light years away.
Now the team of scientists has added data from telescopes at multiple wavelengths of light, each of which reveals different characteristics of the black hole M87 * and the relativistic plasma jet that explodes in space.
“We know the first live picture of a black hole will be fantastic.” Astronomer Kasuhiro Hada said Of the National Astronomical Laboratory of Japan.
“But to use this remarkable image, we need to know everything we can about the behavior of the black hole at that time by observing the entire electromagnetic spectrum.”
There is a lot more to a black hole than the shadow of the M87 * we see in the magnified image and the halo above. The miraculous black hole is active, removing matter from the hot disk of dust and gas around it, which means that some pretty complex things can happen.
One of these is the emission of relative jets from the poles of the black hole.
Once we pass the critical proximity gateway, nothing we can find at the moment escapes from the black hole, but all the objects on the active disk rotating into the active black hole inevitably end up beyond the horizon. A small portion of it somehow travels from the interior of the accretion disk to the poles, where it explodes in space in the form of a jet of ionized plasma, at a significant percentage of the speed of light.
Astronomers believe that the magnetic field of the black hole plays a role in this process. According to this theory, magnetic field lines act in a synchronous manner, accelerating the object at very high speeds before it starts.
According to the M87 *, this is 99 percent of the speed of light – the speed at which relative jets can be obtained – and the jet we can see lasts about 5,000 light-years in space. The light it emits propagates the entire electromagnetic spectrum at least very energetically, so observing this only in one wavelength group does not find some information about the energy of the structure.
Therefore, the Hubble Space Telescope for optical light added group data from telescopes that observe jets at many wavelengths; Chandra X-ray Laboratory and Swift-X-Ray Telescope; Nustar space telescope for high-power X-rays; Neil Kehrals Swift Laboratory for UV and Optical; And Hess, Magic, Veridas and Fermi-Large Area Telescopes for Gas Radiation.

Its primary purpose, the researchers say, is to produce and publish a set of genetic data that astronomers can use for years to study the M87 * and its jets, in an attempt to gain further insight into the phenomenon and how it works.
“Understanding particle acceleration is really central to understanding both EHD film and jets in their ‘colors’.” Said astronomer Sera Markoff Of the University of Amsterdam in the Netherlands.
“These jets are able to carry the energy emitted by the black hole out to a scale larger than the host galaxy. It’s like a large electric pole.
The team’s first analysis of their data is interesting. This shows that during the Horizon telescope observation of the event in April 2017, the area around it was in a dim state that we had not seen. Instead of hardening the shadow of the black hole, it actually made things easier because it means the M87 * is the brightest thing in its immediate environment, not obscured by glare.
Gamma radiation – which can be produced by contact with cosmic rays, the origin of which is not currently known – during those observations they also found that the occurrence of the black hole did not emanate from near the horizon, but somewhere far away.
Precisely there is still a conundrum, but that is the beauty of this work – something that scientists have been constructing for a long time, especially since the phenomenon Horizon telescope continues to operate. It now, at the time of writing, conducts an observational flow, and that data gives scientists a lot of things.
“We know that with the release of this data, along with re-monitoring and improved EHT, we will see many exciting new results on the horizon,” said Yaslav Astronomer Mislav Balokovich. Said.
The results have been released Letters from the Journal of Astronomy.
