Constraining the Nanohertz Gravitational Wave Background with an X-ray Pulsar Timing Array from NICER observations
Tian-Yong Cao, Shi-jie Zheng, Shu-Xu Yi +5
We present constraints on the nanohertz gravitational wave background (GWB) using X-ray pulsar timing data from the Neutron Star Interior Composition Explorer(\textit{NICER}). By a…
