NASA Simulation to Reveal Spiraling, Supermassive Black Holes

A new supercomputer model at NASA could help astronomers find spiraling, merging systems of two supermassive black holes. These mergers happen often in the universe, but are hard to see. The simulation brings scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes spiral toward a collision. Scientists have previously detected merging stellar-mass black holes using the National Science Foundation's Laser Interferometer Gravitational-Wave Observatory (LIGO), but supermassive mergers are much more difficult to find.
