The international team of researchers, some of whom are Russian scientist – Igor Chilingarian of State Astronomical Institute of the Moscow State University Sternberg – discovered a supermassive black hole in the center of the dwarf galaxy.
Ultra-compact dwarf galaxy with an index of M60-UCD1 is located about 54 million light-years from Earth, in the vicinity of an elliptical galaxy with the designation Messier 60. Half the mass of M60-UCD1 concentrated in the central area of the object, which has a diameter of about 160 light years. It is about a thousand times smaller than the size of our entire galaxy.
In the studied galaxy is about 140 million suns. Ultra-compact galaxies are among the most dense stellar systems in the universe. Their weight is usually not more than 200 million solar masses. Such a great value it could be due to the specifications of the galactic evolution of the matter or the presence of a supermassive black hole.
The authors concluded that in the center of M60-UCD1 is a supermassive black hole with a mass of about 15 per cent of the weight of all this dwarf galaxy. For comparison, the mass of a similar hole in the center of the Milky Way is only 0.01 per cent of the total mass of the galaxy.
