New research from A team at the Harvard Astrophysics Center suggests that the large Magelanic clouds, a galaxy of star d, adjacent to the Milky Way, host a gravity structure hundreds of thousands of times the mass of the Sun.
The most widely accepted theory of galaxy evolution believes that ultra-large black holes can only be found in the largest galaxies, such as the Milky Way. Until now, there was no reason to imagine a small cluster like a large Magellan cloud could be hosted. If an X-ray telescope or observatory was trained with small clusters such as a large Magellan cloud, no signatures related to black hole activity were found.
But then the Hyper Belt Lattist came. For nearly 20 years, astronomers have discovered stars that move rapidly, with enough acceleration to be ejected from their galaxy. Traditional stars travel around 100 kilometers per second, while superfast stars travel up to 10 times faster. Experts believe that such stars appear by being “catapulted outwardly” by gravity structures that are super-higher under the mechanism of the hill. This means that the binary star system interacts with the black hole, one star being captured by the black hole, and the other being away from it.
The Milky Way itself has the Hyper Belt Lattister, which was probably born here. Research suggests that they were accelerated by Sagittarius A*, a super-large black hole at the heart of the galaxy. However, at least 21 superfast stars detected are consistent with being ejected by ultrahigh Massive black holes, but cannot be linked to intrinsic activities of the Milky Way. In team simulations it is plausible that these stars instead come from the large Magellan cloud.
For a team led by Jiwon Jesse Han, this is one of the first major evidence regarding the existence of ultra-massive black holes in our adjacent dwarf galaxies. According to the team’s initial calculations, this black hole structure could be between 251,000 and 1 million solar masses. Its average mass is 600,000 times the size of the sun.
the study– Currently available in Preprint, but is featured in the Astrophysical Journal. This used data from the European Space Agency’s Gaia mission.
Of course, there may be other explanations about the phenomenon. Stars that escape from galaxies can come from supernovas or other energy mechanisms that are powerful enough to eject them. However, the authors of the paper explain that this does not seem to be the case for superfast stars that appear to come from the large Magellan cloud.
The large Magelanic Clouds are irregularly shaped galaxies orbiting the Milky Way, along with other d-star clusters such as Sagittarius, Carina, and Draco. It is 163,000 light years from Earth and has a diameter of approximately 14,000 light years. Astronomers believe that in the distant future, in about 2.4 billion years, the large Magellan clouds and Milky Way will merge into a single large cluster, along with other large structures such as the Andromeda Galaxy. Experts believe the merger process is slow and will not cause any problems on a planetary scale.
