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."With a light signature, astronomers could easily pinpoint the cosmic location of these mergers and study them in much more detail than is presently possible," said paper author Barry McKernan, a research associate in the Museum's Department of Astrophysics as well as a professor at the Borough of Manhattan Community College, CUNY, and a faculty member at CUNY's Graduate Center.Black holes form when massive stars die. Much like dense objects sinking into a river on Earth, black holes tend to sink into regions of galaxies where gravity is strongest. It is believed that large numbers of black holes build up in the centers of galaxies, where a much larger, single, supermassive black hole ...
