Galaxy Mergers And Supermassive Black Holes

A team of Japanese scientists using the Subaru Telescope have found two merging galaxies that have active supermassive black holes, and they are certain of at least one. Black holes become active and luminous by accreting large amounts of material around them. Merging gas-rich galaxies with these huge black holes causes active star formation. However, the team also found that not all supermassive black holes in merging galaxies are actively accreting and that multiple black holes have different accretion rates. They concluded that local conditions around supermassive black holes dominate the mass accretion process rather than general properties of the galaxies.
