 Prospects for Future Binary Black Hole GW Studies in Light of PTA Measurements / Ellis, John ; Fairbairn, Malcolm ; Hütsi, Gert ; Raidal, Martti ; Urrutia, Juan ; Vaskonen, Ville ; Veermäe, Hardi NANOGrav and other Pulsar Timing Arrays (PTAs) have discovered a common-spectrum process in the nHz range that may be due to gravitational waves (GWs): if so, they are likely to have been generated by black hole (BH) binaries with total masses $> 10^9 M_{\odot}$.
