In the final stage of unification of the galaxies, the black holes that were in the center of each other were combined to capture the rare scene just before the formation of a very large black hole.
A team of researchers from the American scientific research company Eureka Scientific, Dr. Michael Kos, reported that more than 20 years of data had been collected by the Hubble Space Telescope and the WM Keck Observatory telescope in Hawaii . In a recent issue of the journal Nature.
It is stated that the galaxy merges with the Andromeda galaxy, which can occur in billions of years, as well as with the situation in the early days of the formation of the Andromeda galaxy, which can occur in billions of years, as well as with the situation in the early days of the formation of the galaxy. universe, where the galaxy fuses more frequently.
Dr. Kos' research team began the study by examining the image of the Hubble Telescope that captured the "NGC6240". in which the two galaxies interacted.
First, we badyzed 10-year X-ray observations of BAT, an automatic space-explosion observation instrument mounted on NASA's Nilgrele Swift space telescope, and found fuzzy but active black holes. X-rays can penetrate the thick clouds of dust and gas that cover the center of the galaxy and can be observed by measuring them.
Then, we focused on the coalesced galaxy found in the X-ray data, followed the Hubble telescope data and observed in the Keck telescope's near-infrared near-vision that is not in the Hubble telescope data.
The researchers badyzed a total of 481 galaxies, including 96 galaxies measured by the Keck telescope and 385 galaxies obtained by the Hubble telescope. These galaxies are about 330 million light years away and most of them are about the size of our galaxy and the Andromeda galaxy.
As a result, it was found that the number of galaxies with black holes just before incorporation reached 17%. In computer simulations, this step is very short and the researchers say that they did not expect to find a black hole just before the merger of so many galaxies.
In a comparison of 176 different galaxies with lower black hole activity, only 1% of the galaxies had a black hole just prior to melting.
The research team confirmed that the brilliant spark at the center of the interacting galaxy indicates that two rapidly expanding black holes merge. This has been theoretically predicted up until now, but this has not been proven by observation.
The central part of the galaxy coalesces is covered with a thick layer of dust and gas, making it difficult to observe the ocean. For this reason, it is said that the closest black hole observed up to now is 10 times farther than that observed this time.
Dr. Cos said: "I have done a lot of research to observe the close interaction of the black hole, but it is the x-ray that could penetrate the dust that made it possible."
NASA's next-generation infrared telescope, the James Web Space Telescope (JWST), is expected to be launched in 2021, which will provide detailed insight into the mbad and rate of black hole growth across the planet. Thick clouds of dust and gas.
