Constraints on ultra-low-frequency gravitational waves with statistics of pulsar spin-down rates

Hiroki Kumamoto, Yuya Imasato, Naoyuki Yonemaru +2

We probe ultra-low-frequency gravitational waves (GWs) with statistics of spin-down rates of milli-second pulsars (MSPs) by a method proposed in our prevous work (Yonemaru et al. 2…
