Team Astronomers have discovered a curious personality in the universe. They are two distant galaxies colliding with each other to form a larger structure. From the point of view of the Earth, the intersection of the eighth lying tablets is similar to the endless code (∞).
Because of this similarity, the researchers – who reside at the universities of Yale and Copenhagen – called it “Infiniti the Galaxy” and the details of their discovery in a paper published in Astronomical Physics Magazine messages. Besides its exciting shape, the structure raises the interest of scientists because of its contents: within it can be the first direct evidence of a newly formed black puncture that has been formed.
Pictures were taken through James Web telescope for space Then he enriches information from Chandra X -ray ObservatoryThe most powerful X -ray telescope that was ever created. The light comes from this galaxy from a time when the universe was 470 million years ago – 13.5 billion years ago. In the structure of the dual galaxy, at least no less than uniform black holes can be observed, each of which is concentrated in a concerned disk (the yellow points in the image below), and an area of compressed gas at the intersection point indicates that there is an ultra -mass object (green point).
Scientists believe that they may have seen signs of a direct black hole. Usually, black holes are formed when the stars are running out of fuel and collapse under their own attractiveness, but there is an alternative formation phenomenon Discuss astronomical physicsWhere a black hole is formed through the collapse of the giant gas cloud, without the formation of a star. Theoretical of such a possibility has been done, but this type of black hole has not yet noticed.
The largest black holes in the universe, which are super black holes, were identified in galaxies that were formed only a few hundred years after the big explosion. But what made their formation possible is not completely understood yet. Many super black holes are believed to have become the result of the merging of smaller black holes. But with very ancient black holes, it does not seem to have enough time for the first stars in the universe to develop, and the collapse of black holes in the stellar mass, and then that to merge To huge sizes, SuperMassive.
Therefore, some astronomers suggested an alternative to the first super black holes in the universe. According to this hypothesis, black holes will not need to be formed from a star or arise from mergers. Instead, the theory says, dense blocks of the material that in other cases led to galaxies that can be pressed directly in huge black holes. Scientists are currently achieving in this scenario, although the decisive evidence of its occurrence is still not present.
Infinity Galaxy can provide evidence to reveal the possibility of this second track of training. “During the collision, the gas is shocked inside these two galaxies and pressure. This pressure may be sufficient to form a dense knot, then collapsed into a black hole,” Peter Van Docum, Professor of Astronomy and Physics in Yale and Coauthor on paperHe said in a post on University website. “While such collisions are rare events, extremist gas densities are believed to have been very common in the oldest cosmic era, when galaxies began to cost,” Van Docum added.
Scientists also study other alternatives less exciting regarding what is going on in the Infinity Galaxy. Instead of its creation through a direct collapse of the gas, this potential additional black hole – the green spot in the image above – can be signs of a black hole that is removed from another galaxy where the “infinity” pass. Another possible scenario is that this image actually shows the collision of three galaxies, with the third eclipse by the other big.
Currently, the team says the initial results are exciting. “We cannot categorically say that we have found a direct black hole for collapse. But we can say that this new data enhances the situation in which we see a newborn black hole, while getting rid of some competing explanations,” Van Docum concluded in a blog. Nasa.
