Discovered a hidden black hole in a galaxy

Discovered a ‘hidden’ black hole in a galaxy: it was discovered outside the Milky Way by the effects of its gravitational pull on a star and opened new frontiers for the first time. An international team led by Sarah Saracino John Moores of the University of Liverpool, the Palermo Astronomical Laboratory of the National Astronomical Institute, also took part in discovering the South European Laboratory’s largest telescope (Vlt – Eso). (ENAF) The results are published in the monthly announcements of the Royal Astronomical Society.

“Like Sherlock Holmes chasing a criminal, we noticed that every star in this cluster was looking for evidence for the existence of black holes without looking directly through a magnifying glass,” Saracino explained. Criminal ‘: A black hole 11 times the mass of the Sun, its existence changes the orbit of a nearby large star inside the constellation NGC 1850. Identifying the black hole is a very difficult task, can it be confirmed by X-ray emissions that occur only at certain stages in recent years or by gravitational waves that form when black holes merge with each other or when a neutron star connects? It now opens up important new possibilities for tracking black holes: “It’s one of the ‘wanted criminals’, but when you have one you are well on your way to finding many more.

It is possible to recognize the effects of black holes in the orbits of nearby stars by data collected over a period of about 2 years using the Muse instrument (Multi Unit Spectroscopic Explorer) installed on the Vlt Telescope in the Atacama Desert, Chile. “Muse – Sebastian Kaman, one of the authors of the Liverpool Institute of Astrophysics and Research, commented:” Allowing us to observe the most congested areas, such as the inner parts of star clusters, and to analyze the light of each nearby star, we received information about thousands of stars at once. At least 10 times as much.
