Three-band dark-siren cosmology with intermediate mass black hole binaries: Synergy of Taiji, LGWA, and the Einstein Telescope
Ji-Yu Song, Yue-Yan Dong, Shang-Jie Jin +3
Gravitational-wave (GW) dark sirens provide an independent probe of the cosmic expansion history. Their cosmological constraining power, however, depends critically on precise lumi…
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…
Gravitational wave standard sirens: A brief review of cosmological parameter estimation
Shang-Jie Jin, Ji-Yu Song, Tian-Yang Sun +5
Gravitational wave (GW) observations are expected to serve as a powerful and independent probe of the expansion history of the universe. By providing direct and calibration-free me…
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…
