Dual Supermassive Black Hole Candidates

Leave a Comment Using publicly available data from the AGN and Galaxy Evolution Survey (AGES), conducted at the MMTO with the hectospec instrument, researchers have discovered seven new candidates for dual supermassive black hole systems in the centers of galaxies. Based on the new findings, they suggest that the number of galaxies containing dual supermassive black holes decreases over time, likely because more galaxies merged together in the past. AGES is a joint Arizona/CfA collaboration.
