There are black holes, up to 100 times the mass of the Sun.
Researchers from the National astronomical Observatory of Japan (NAOJ) for the first time evidence for the existence of mysterious invisible black hole that wanders through our galaxy.
A Preprint of the article can be found on the website arXiv, and briefly talks about the opening of the portal, Science Alert. The authors believe that they managed to solve one of the cosmological mysteries.
It is known that there are black holes, up to 100 times the mass of the Sun, and supermassive, with a mass of 100 thousand and more times exceeds sun. It is believed that the range between them must also exist black holes. However, until recently, to detect them failed.
Scientists from Japan with the help of a radio telescope Atacama Large Millimeter / Submillimeter Array (ALMA) have detected a flow of molecular gas rotating around an invisible massive object.
In their opinion, this object is a rogue black hole, located at a distance of about 20 light-years from the center of the milky Way. It is named HCN-0,009-0,044. The calculations showed that the mass of the elusive black hole is about 32 thousand masses of the Sun.
