Scientists successfully capture multi-band fingerprints of black holes: Will verify Einstein’s general theory of relativity

Recently, “Astrophysical Journal Newsletter” published an academic report that scientists successfully captured the multi-band fingerprints of black holes, which is expected to test Einstein’s general theory of relativity.

In the observational research,

scientists coordinated 19 telescopes (arrays) around the world on the black hole and its jet radiation, and carried out multi-band simultaneous observations with the widest frequency coverage so far, and successfully collected observations from the end of March to mid-May 2017 Data, and thus successfully captured the “fingerprint” of the supermassive black hole in the center of the M87 galaxy.

It is reported that the above results are expected to give mankind an unprecedented understanding of this black hole and the system it drives, and improve the test of Einstein’s general theory of relativity.

Kazuhiro Hada of the National Astronomical Observatory of Japan,

a collaborator of this new research, said: “In order to get the maximum effect from this extraordinary image, we need to understand all the behavior of black holes at that time through observations of the entire electromagnetic spectrum.”

The huge gravitational force of a supermassive black hole can provide energy for particle jets that travel long distances at almost the speed of light. The light generated by the M87 jet spans the entire electromagnetic spectrum, from radio waves to visible light to gamma rays.

Every black hole has a different pattern.

Recognizing this pattern can give us an important understanding of the nature of a black hole—for example, its rotation and energy output—but it is a challenge because the pattern will change over times

 

Each telescope can provide different information about the behavior and impact of the 6.5 billion solar-mass black hole at the center of M87, which is about 55 million light-years away from Earth.

The data was collected from a team of 760 scientists and engineers from nearly 200 institutions in 32 countries or regions, using observatories funded by global institutions and institutions. Observations were concentrated from the end of March to mid-April 2017.

The first result shows that the light intensity

produced by the matter around the M87 supermassive black hole is the lowest observed so far. This creates ideal conditions for observing the “shadows” of the black hole, and at the same time it can isolate the light near the EHT from the light tens of thousands of light-years away from the black hole.

The combination of data from these telescopes and current (and future) EHT observation data will enable scientists to conduct important research on some of the most important and challenging fields of astrophysics research.

Scientists are looking forward to more amazing results of EHT in the next few years: “Understanding particle acceleration is essential for us to understand all the’colors’ of EHT images and jets,” said Sera Markoff, a collaborator from the University of Amsterdam: “We The results will help us calculate the energy carried and the impact of the black hole jet on the environment.”
