In Institute for extraterrestrial physics, max Planck Society and the University Observatory of Munich have found a black hole mass of 40 billion Suns. It is reported Phys.org.
Supermassive black hole is almost extinct in the galaxy Holm 15A in the cluster of galaxies Abell 85. It is distant from the Earth at a distance of 700 million light years and has a mass of about two trillion Suns.
The analysis of the photometric data showed that the detected object is the most massive black hole in the local Universe. Such masses have only black holes located in quasars at a distance of about 10 billion light years from Earth.
Holm 15A mass calculated on the basis of the movements of stars around the galactic core. Previously, a similar method was used for calculations with objects twice as closer to the Ground.
Such a supermassive black hole could be formed after the collision of several galaxies merge and their black holes.
