4 billion 500 million light-years away outside the lens Galaxy "wandering black hole" black holes in the universe how much as shown in the figure, this is the Harbert space telescope lens Galaxy XJ1417+52, astronomers discovered that distant galaxies have a black hole wandering outside. According to the science news website, astronomers have discovered that there is a black hole in the outer region of the lens Galaxy GJ1417+52, evidence suggests that the black hole is about 100 thousand times the mass of the sun. Astronomers know that a black hole is usually 10-100 times the mass of the sun, and it is the remains of a dying star. The supermassive black hole is 100 thousand -100 times the mass of the sun and is located in the center of the galaxy. But there are some mysterious black holes in the universe, which are 100-100000 times the mass of the sun, which is hard to find. Scientists have pointed out that a galaxy and another supermassive black hole in the collision of the merger, the two galaxies supermassive black holes and medium mass black holes may be away from the center of the galaxy. As the stars, gas, and dust pass through the first galaxy from second galaxies, the black hole is moving. At present, the United States University of New Hampshire Lin Dacheng (transliteration), the formation of a team of astronomers to study and analyze, they use "Chandra" and "XMM-" Newton X – ray observatory found outside the GJ1417+52 lens Galaxy have a stray black hole, GJ1417+52 lenticular Galaxy about 4 billion 500 million light-years from earth. The lens Galaxy GJ1417+52 is very bright, assuming that the radiation force of the surrounding material is equivalent to the gravitational force, which is likely to have a mass of 100 thousand times that of the sun. Chandra X ray observatory data show that XJ1417+52 releases a large amount of X rays, which is an ultra bright X ray source (HLX). (long compile)相关的主题文章:
