Prospective constraints on dark energy from nanohertz individual gravitational wave sources
Qing Yang, Gu-yue Zhang, Yi Huang +1
Nanohertz gravitational waves (GWs) from supermassive binary black holes (SMBBHs), detectable via pulsar timing arrays (PTAs), offer a novel avenue to constrain dark energy. Based…

Anisotropy of Nanohertz Gravitational Wave Background and Source Clustering from Supermassive Binary Black Holes Based on Cosmological Simulation
Qing Yang, Xiao Guo, Zhoujian Cao +2
Several pulsar timing array (PTA) groups have recently claimed the detection of nanohertz gravitational wave background (GWB), but the origin of this gravitational wave (GW) signal…
