Pulsing light may indicate supermassive black hole merger

20 abril 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 present direct evidence of a pulsing quasar, which may substantiate the existence of black hole binaries.
