M22 star cluster in our
galaxy is located at a distance of 10,000 light-years from Earth. Administer to
make a discovery by observing a super-large array radio telescopes located in
New Mexico.
U.S. astronomers have
detected about two separate black holes in the same star cluster M22, located
in the constellation Sagittarius. The paper was published in the journal
Nature, a summary of its results ScienceNow.
M22 star cluster in our
galaxy is located at a distance of 10,000 light-years from Earth. Managed to
make a discovery by observing a super-large array radio telescopes located in
New Mexico. Scientists have discovered two separate radio signal coming from
the star cluster, the characteristics of which resembled the radio signals from
the known black holes. Either neutron stars or white dwarfs could not,
according to astronomers, be the source of these signals.
The authors believe
that the source of the radio signal is two separate massive black holes are
located near the center of the cluster. If so, it will be the first cluster M22
star cluster in the Milky Way, which discovered black holes, and the first
cluster, which found a pair of black holes. According to astronomers, this is
quite unusual, because the gravitational interaction of black holes had to
leave only one of them in the center of a cluster of stars.
Star clusters are
called clusters of stars inside galaxies associated gravitational forces and
moving together. Most star clusters in the Milky Way were formed a long time
ago, so they are massive stars had to go out and turn into a black hole.
Earlier, another group
of scientists were the first to measure the jet base supermassive black hole -
a jet of heated substances emitted perpendicular to the accretion disk.
