Synergy between CSST and future gravitational-wave detectors: Probing primordial black holes by cross-correlating dark sirens with galaxies
Ya-Nan Du, Ji-Yu Song, Jing-Fei Zhang +1
Gravitational-wave (GW) events and galaxies both trace the cosmic matter distribution, but the mergers of astrophysical black holes and primordial black holes (PBHs) are expected t…

Multi-band cross-correlation dark sirens: Enhancing cosmological parameter and gravitational-wave bias constraints
Ji-Yu Song, Ya-Nan Du, Yue-Yan Dong +2
Multi-band gravitational-wave (GW) observation, combining space-borne and ground-based detectors across different frequency bands, can improve the sky localization of compact binar…

Synergy between CSST and third-generation gravitational-wave detectors: Inferring cosmological parameters using cross-correlation of dark sirens and galaxies
Ya-Nan Du, Ji-Yu Song, Yichao Li +4
Gravitational-wave (GW) events are generally believed to originate in galaxies and can thus serve, like galaxies, as tracers of the universe's large-scale structure. In GW observat…
