Black hole in Messier 87 Has Jet Pushing Cosmic Speed Limit, Using the Chandra X-ray Observatory, astronomers have discovered that the giant black hole famous at Messier removes 87 particles at speeds of more than 99% of the speed of light.
In collaboration with the Horizon Telescope, the first image of a black hole was observed last April, which observed a large dark object at Messier 87 or the center of the M87 galaxy. This black hole is about 6.5 billion times the mass of the Sun and about 55 million light years from Earth.
The black hole is called astronomer M87 * and was recently given the Hawaiian name “Powehi”. and the black hole has jet pushing cosmic speed limit.
For years, astronomers have observed radiation from the flow of high-energy particles – driven by black holes – that explode from the center of M87. They checked the jets on radio, optics and X-rays, including Chandra.
And now, based on Chandra’s observations, researchers have seen that jet parts travel almost at the speed of light.
When the material approaches the black hole to taste, it enters a vortex model called the accretion disk. Part of the inside of the folding disc falls on the black hole and part of it folds from the black hole in the form of a narrow beam or ray of material along the magnetic field line.
Because this inflation process is irregular, the nozzles consist of lumps or vertices which can sometimes be identified with Chandra and other telescopes.
The researchers used Chandra’s observations from 2012 and 2017 to track the movements of two X-ray units on the plane, which are around 900 and 2500 light years from a black hole.
X-ray data shows a real speed of 6.3 times the speed of light for an X-ray node closer to a black hole and 2.4 times the speed of light for another.
Ultra-light motion occurs when objects move near the speed of light in a direction close to our line of sight. The light moves almost as fast as the light it creates, creating the illusion that the movement of light is much faster than the speed of light. In the case of M87 *, the jet is oriented close to our direction, which leads to this exotic artificial speed.
So far, astronomers have observed such movements in M87 jets * at radio wavelengths and optical wavelengths, but have not been able to show clearly that matter moves in jets at the very low speed of light. For example, moving features can be waves or shocks, such as sonic explosions, and do not track the movement of matter.
This latest result shows the ability of X-rays to act as an accurate space speed cannon. The team found that its function, moving at speeds that are seen 6.3 times the speed of light, also decreased by more than 70% between 2012 and 2017. This decay is likely due to the loss of particle energy caused by disruption of emissions around the magnetic field.
To do this, the team must see X-rays of the same particle which are not moving in waves twice.
Chandra data is a great addition to EHT data. The size of the ring around the black hole seen with the Event Horizon telescope is about one hundred million times smaller than the size of the jet observed at Chandra. Another difference is that EHT monitors M87 for six days in April 2017 to get a portrait of the current black hole. Chandra’s observations examined material fired into jets from black holes hundreds and thousands of years ago.
The Event Horizon telescope looks like a close-up of a launch rocket, researchers said.
