On using inspiralling supermassive binary black holes in the PTA frequency band as standard sirens to constrain dark energy

Changshuo Yan, Wen Zhao, Youjun Lu

Supermassive binary black holes (SMBBHs) in galactic centers may radiate gravitational wave (GW) in the nano-Hertz frequency band, which are expected to be detected by pulsar timin…
