Pulsing light may indicate supermassive black hole merger
College Park MD (SPX) Apr 24, 2015
As two galaxies enter the final stages of merging, scientists have theorized that the galaxies' supermassive black holes will form a "binary," or two black holes in such close orbit they are gravitationally bound to one another. In a new study, astronomers at the University of Maryland present direct evidence of a pulsing quasar, which may substantiate the existence of black hole binaries. "We believe we have observed two supermassive black holes in closer proximity than ever before," said Suvi Ge ... read more
