An international team of scientists, which entered a leading researcher at the State Astronomical Institute of the PK Moscow State University Sternberg Igor Chilingarian , found in the dwarf galaxy M60-UCD1 supermassive black hole, thus proving that they are found not only in large galaxies such as our Milky Way, reports “Times” with reference to the journal Nature.
Ultra-compact dwarf galaxies are among the most dense star systems in the universe. Now they know about a hundred. They belong to the galaxy M60-UCD1, one of the largest galaxies of this type, which is from the Earth at a distance of 54 million light-years away and is a satellite galaxy ?? M60.
A team of astronomers interested in this mini-galaxy last year, finding out that she has an abnormally high density and in addition has an internal source of gamma radiation. This year, they analyzed their observations at the telescope Geminy North, located on the Hawaiian Islands, and snapshots Space Telescope “Hubble».
The authors found that the stars in the dwarf galaxies are moving at speeds of 100 kilometers per second, and this for the simple star clusters too quickly and can be explained only by the presence of a large black hole.
The scientists also calculated its mass, which turned out to be five times greater than the mass of the central black hole in our galaxy.
Scientists believe that the M60-UCD1 is a remnant of the once very large elliptical galaxy, composed probably about 10 billion stars, this galaxy is about 10 billion years ago, met with an even larger M60, which fleeced her disrupting its gravity most of the stellar material.
