Black Hole Emanating Magnetic Lines (IMAGE) Rochester Institute of Technology Caption Magnetic field lines emanate from a pair of supermassive black holes nearing merger within a large gas disk in a simulation by RIT scientists. Periodic light signals in the gas disk could someday help scientists locate supermassive binary black holes.
