The observation of gravitational-waves from merging supermassive black holes
will be transformative: the detection of a low-frequency gravitational-wave
background can tell us if and how supermassive black holes merge, inform our
knowledge of galaxy merger rates and supermassive black hole masses, and enable
the possibility of detecting new physics at nanohertz frequencies. All we have
to do is time pulsars.
