The recent direct detections of gravitational waves (GWs) from merging black holes by the Laser Interferometer Gravitational-wave Observatory (LIGO) marks the beginning of the era of GW astronomy and promises to transform fundamental physics. In the coming years, there is hope for detections across the mass scale of binary black holes.
Pulsar Timing Arrays (PTAs) are galactic-scale low-frequency (nHz - $\mu$Hz) GW observatories, which aim to directly detect GWs from binary supermassive black holes (SMBHs) ($\gtrsim 10^{7} \msun$). The frequency and black hole mass range that PTAs are sensitive to is orders of magnitude different from those LIGO is observing, …
