New research from The Harvard Center for Astrophysics suggests that the Grand Magelan Cloud, the Galaxy Dwarf Galaxy is the Milky Way, is the host of the gravitational structure of hundreds of thousands of the sun: a potential supermassive black hole.
The most commonly accepted theory of galactic evolution believes that supermassive black holes are only found in the largest galaxies, such as the Milky Way. So far, there was no reason to imagine that a small cluster like a large magelan cloud could host one. When X-ray telescopes or observators are trained on smaller clusters such as a large magelan cloud, they did not find signatures associated with black activities holes.
But then the stars of Hypervelocity came. Almost 20 years of astronomers noticed a fast journey of the star with enough acceleration to be ejected from their own galaxies. While the traditional star ranges about 100 kilometers per second, the star of hypervelocity is traveling up to 10 times faster. Experts think that such stars appear “cadapulted outwards” under the supervision of the gravitational structure under the mechanism of the hill – which is a binary star system with a black hole, with one star trapped by black holes, and the other from it.
On the milky path are hypervelocational stars that are probably created here. Studies suggest that they accelerated the shooter A *, supermasive black hole in the center of the galaxy. But at least 21 stars of Hypervelocity were discovered in accordance with the ejecting of a supermassive black hole, but it cannot be associated with the internal activity of the Milky Way. In the team simulations, it is credible for these stars to encourage these stars from the Great Magelan cloud.
For a team, led by Jiwon Jesse Han, this is one of the first main evidence for the presence of a supermassive black hole in our neighboring Dwarf Galaxy. According to the initial calculations of the team, this structure of the black hole could be between 251,000 and 1 million solar masses. His average mass would be 600,000 times bigger than the sun.
The study – currently in the Pretprint, but was published in the Astrophysical magazines used by the European Space Agency of Gaia Mission, whose purpose is to map millions of stars to calculate their movement.
It could, of course, be able to be able to be the second explanations for the phenomenon. The stars fleeing from their galaxies could arise from supernova or any other energy mechanism enough powerful to eject them. The authors of the newspaper explain, however, that it does not seem to be a case with the stars of hypervelocity, which look from the Great Magelan cloud.
The Grand Magelan cloud is irregular in the form of milk-shaped galaxies, along with other clusters of dwarf stars, such as arrows, customs or draco. It is 163,000 light years from the land and has a diameter of about 14,000 light years. Astronomers believe that in a distant future – for about 2.4 billion years – a large magelan cloud and a milky path will be connected into a larger cluster, along with other major structures, such as Galaxy Andromed. Experts believe that the merger process will be slow and, on the planetary extent will no problems represent.
