Galaxy mergers reveal pairs of supermassive black holes

An article published in the journal “Nature” describes the discovery of five pairs of supermassive black holes in galaxies in the final stages of mergers. A team of researchers coordinated by the University of Maryland used data gathered at the Keck Observatory in Hawaii and in over twenty years by the Hubbble space telescope to find out these cases among hundreds of galaxies selected from those with strong X-ray emissions detected by the Swift space telescope.
