Gravitational wave detectors are finding black hole mergers in the universe at the rate of one per week. If these mergers occur in empty space, researchers cannot see associated light that is needed to determine where they happened. However, a new study in The Astrophysical Journal Letters, led by scientists at the American Museum of Natural History and the City University of New York (CUNY), suggests that researchers might finally be able to see light from black hole mergers if the collisions happen in the presence of gas.
