Incredible New Observation Shows Supermassive Black Holes Orbiting Each Other

Do you think our galaxy is special? Ha. Our drilling roll of gas and dark matter could be a good place for humans.

But within hundreds of light years, there is an elliptical galaxy, Galaxy 0402 + 379, that supermassive black holes are orbiting just 24 or more years of light. Their combined weight is about 15 billion times that of our sun.

If not convinced, a team led by scientists at the University of New Mexico has actually detected black holes moving relative to each other using the Very Long Baseline Array, a system of ten radio telescopes in the United States, with locations in Hawaii And the Caribbean.

Not only is it the first direct measurement of the galactic centers orbiting that way, but it was a difficult calculation to realize.

One of the study’s authors, Roger Romani of Stanford University, told Gizmodo: “I think it’s a tour de force technique to measure such movement in the sky,” a-t said. “It took me ten years of measurement with the largest telescope network on earth.”

These black holes are large, probably a few thousand times more massive than the monster in the center of the Milky Way, Sagittarius A *. They are probably the result of a set of fused galaxies, according to Romani.

And although they are 24 light-years away, it’s actually a very narrow range in regards to the orbit of black holes. “Two approaching black holes are quite exceptional,” he said. Even so, it would take about 30,000 years for the giants to complete a full orbit. The researchers published the results in The Astrophysical Journal.
Capturing a movement of this type of distant sources in the sky requires using the VLBA, a radio telescope set up to perform very long base interferometry or VLBI.

In essence, the Earth itself is transformed into a telescope, but instead of focusing light on a mirror as a simple telescope, light is captured on individual radio telescopes and the focus is by comparing the information contained in supercomputers . These types of observations allow researchers to solve very remote but relatively important things.

Other researchers were delighted to observe. “This is an absolutely wonderful result.This is a very convincing proof of what would be the first binary black hole known visual observed supermassive,” meaning a pair of very solid black holes that can be solved separately with a light telescope Grant Tremblay, an astrophysicist at Yale University and Harvard Gizmodo.

“It will be very convincing target tracking for years to come.” Romani emphasized that studying binary black holes like these could help understand how black holes are joining in the center of large galaxies.

Another astronomer Sarah Spolaor at the University of West Virginia explains how these binary black holes are hard to find and none of the candidates is not completely confirmed (though this one). She always thought this observation was exciting.

“Its target source 0402 + 379 … is one of the most credible candidates for a number of reasons, perhaps one of the highlights is that it has actually been” photographed “and we can see the material clearly mark the two holes Blacks, “he said.

“Therefore, the discovery of the orbital motion at 0402 + 379 would be a dream come true for many,” and perhaps one day scientists may be able to make a video on the radio waves of orbiting black holes.

He emphasized that “the orbital movement is not the only possible explanation of what they saw,” Romani said. You will feel more confident after taking more data for longer. Or maybe they can find another pair in orbit.
