New research from A group at the Harvard Astronomical Center shows that the large cloud of Magellan, a nearby dwarf galaxy GalaxyStore an attractive structure hundreds of thousands of times sun: A super potential black hole.
The most widely accepted theory of galaxy evolution suggests that super large black holes are only found in the largest galaxies, like the galaxy. Until now, there is no reason to imagine that a small cluster like a large Magellan cloud can store a large Magellanic cluster. When X -ray telescopes or observatory have been trained on smaller clusters such as big clouds Magellanic, they have not found any signature related to the activity of black holes.
But then to the super -speed stars. For nearly 20 years, astronomers have discovered fast travel stars with enough acceleration to be pushed out of their own galaxies. While a traditional star moves at a speed of about 100 km per second, a super -speed star travels up to 10 times faster. Experts think that such stars appear by being transformed outside by a super -huge attractive structure in the hilly mechanism, which is where a binary star system interacts with a black hole, With a star caught by black holes and the other flew out of it.
In the Milky Way, there are Hypervelocity stars that can originate here. Studies show that they are accelerated by Sagittarius A*, super large black holes in the center of galaxy. But at least 21 super -speed stars were discovered suitable for being pushed out by a super -large black hole but could not be associated with the internal activity of the galaxy. In the group's simulation, the reason is that these stars instead originated from the large clouds of Magellanic.
For the team, led by Jiwon Jesse Han, this is one of the first evidence for the presence of a super -large black hole in our vicinity. According to the initial calculation of the group, this black hole structure can range from 251,000 to 1 million solar mass. Its average weight will be 600,000 times the sun.
StudyCurrently in the printed version but will be published in the journal Physics, data used data from the Gaia mission of the European Space Agency, with the purpose of mapping millions of stars To calculate their motion.
Of course, there may be other explanations for this phenomenon. The stars escaping from their galaxies can also originate from a super neo or any other energy mechanism strong enough to push them. However, the authors of the article explained that this seems to be the case with super -speed stars that seem to come from the big Magellanic cloud.
The large cloud of Magellan is an irregular shape around the galaxy, along with other dwarf clusters, such as Sagittarius, Carina or Draco. That is 163,000 light -years from the Earth and has a diameter of about 14,000 light -years. Astronomers believe that in the distant future in about 2.4 billion years, the large cloud of Magellan and the galaxy will merge into a larger cluster, along with other larger structures, like Thien Ha Andromeda. . Experts believe that the merger will be slow and on the scale of the planet, will not raise any problems.
