Red noise and evolving signals: a complete frequentist approach to supermassive black hole binary searches with pulsar timing array
Xuan Tao, Boris Goncharov, Yiqian Qian +2
Searches for gravitational waves (GWs) from isolated supermassive black hole binaries (SMBHBs) in pulsar timing array (PTA) data require simultaneous estimation of signal and noise…

Detection and parameter estimation of supermassive black hole ringdown signals using a pulsar timing array
Xuan Tao, Yan Wang, Soumya D. Mohanty
Gravitational wave (GW) searches using pulsar timing arrays (PTAs) are commonly assumed to be limited to a GW frequency of Hz given by the Nyquist rate as…
