A team of scientists led by Jonathan Williams from the University of Maryland discovered a cluster of three
Scientists used data from 27 radio telescopes inNew Mexico (USA) VLA, European Southern Observatory, W. M. Keck Observatory and Chandra X-ray Observatory and ALMA radio telescope (Atacama Large Millimeter / Submillimeter Array).
The unique system was found in a bright area of the sky at a distance of about 800 million light years from Earth.

All three galaxies in it are different from each other.One of them is the Seyfert galaxy. Let us remember that this is a spiral or irregular galaxy with an active nucleus, the emission spectrum of which contains many bright wide bands, which indicates powerful gas emissions at speeds of up to several thousand kilometers per second.
The second galaxy, according to somescientists, also contains supermassive black holes at its center. The third, a dwarf cluster of stars without an active supermassive black hole, leaves behind a trail of dust and moves perpendicular to the Earth.
It was this unique combination of galaxies that allowed scientists to obtain data on the physical characteristics of the merger that would otherwise be undetectable.
