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…
Cosmological prospects for multiband detection of intermediate-mass binary black holes with Taiji and ground-based detectors
Yue-Yan Dong, Ji-Yu Song, Jing-Fei Zhang +1
Intermediate-mass black holes (IMBHs) bridge the gap between stellar-mass and supermassive black holes, but remain challenging to detect electromagnetically. Gravitational-wave obs…
Three-band dark-siren cosmology with intermediate-mass black hole binaries: synergy of Taiji, LGWA, and 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…
Prospects for joint multiband detection of intermediate-mass black holes by LGWA and the Einstein Telescope
Yue-Yan Dong, Ji-Yu Song, Jing-Fei Zhang +1
Gravitational-wave (GW) detection offers a novel approach to exploring intermediate-mass black holes (IMBHs). The GW signals from IMBH mergers mainly fall in the decihertz frequenc…
Enhancing dark siren cosmology through multi-band gravitational wave synergetic observations
Yue-Yan Dong, Ji-Yu Song, Shang-Jie Jin +2
Multi-band gravitational-wave (GW) standard siren observations are poised to herald a new era in the study of cosmic evolution. These observations offer higher signal-to-noise rati…
