Russian Federation has created a technique for studying systems of double supermassive black holes

Scientists from the Crimean Astrophysical Laboratory of the Russian Academy of Sciences have proposed a new method for studying systems of double supermassive black holes. These objects, as experts suggest, are formed during the merger of galaxies.

The developed method allows to calculate their masses, orbital parameters, velocities, energy reserves and losses, as well as the period of life before the merger.

"The new method is based on long-term observational data of five blazars. They were studied using the 22-meter radio telescope RT-22 in Simeiz (Crimea). The history of continuous monitoring exceeds 50 years. Analyzing the information accumulated over this time, makes it possible to draw reliable conclusions about the properties of space objects. In particular, the researchers identified a class of objects with a special periodicity of radiation. Modeling showed that all five blazars - a system of paired supermassive black holes, and periodicity may be associated with their orbital motion at the stage of merger," - told "Izvestia" Deputy Director of KRAO RAS Alexander Volvach.

According to him, double supermassive black holes are a powerful source of gravitational waves. Their study will make it possible to clarify the size of the universe, better understand the nature of space-time and develop ultra-precise measuring equipment.
