New Research From Harvard Astronomers Provides Clear Evidence for Moving Black Hole
Dominic Pesce said in an email that the findings of the study are significant in two ways. “At a surface level, these findings are significant for adding a data point to our currently nearly-empty list of known mobile supermassive black holes,” he said. “Looking at a somewhat bigger picture, these mobile [black holes] are evidence of supermassive black hole growth in action. A supermassive black hole that is moving with respect to its host galaxy is a strong indication that the system is either about to experience a supermassive black hole binary merger, or that it has recently done so.” In either scenario, the movement provides “exciting indirect evidence for the reality” of supermassive black hole mergers, he said.
