Two-Dimensional Pulsar Distance Inference from Nanohertz Gravitational Waves
Si-Ren Xiao, Ji-Yu Song, Yue Shao +3
Pulsar timing arrays (PTAs) are limited in localizing nanohertz continuous gravitational waves (CGWs) by uncertainties in pulsar distances. We introduce a method to infer pulsar di…

Nanohertz gravitational waves from a quasar-based supermassive black hole binary population model as dark sirens
Si-Ren Xiao, Yue Shao, Ling-Feng Wang +4
Recently, several pulsar timing array (PTA) projects have detected evidence of the existence of a stochastic gravitational wave background (SGWB) in the nanohertz frequency band, p…
