Pulsing light reveals supermassive black hole merger

As two galaxies enter the final stages of merging, their supermassive black holes form a “binary” or two black holes that are gravitationally bound to one another. Now, astronomers from University of Maryland have found direct evidence of a pulsing quasar which may substantiate the existence of black hole binaries.
