Probing supermassive black hole binaries with pulsar timing

Nature Astronomyvolume 3pages810 (2019) | Download Citation

The detection of a gravitational-wave background at nanohertz frequencies can tell us if and how supermassive black holes merge, and inform our knowledge of galaxy merger rates and supermassive black hole masses. All we have to do is time pulsars.
