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…

Model-independent H0 from GWTC-4 standard sirens and TDCOSMO 2025 strong lensing time delays

En-Yu Xiong, Ji-Yu Song, Jing-Fei Zhang +1

The significant discrepancy between early- and late-Universe measurements of the Hubble constant, known as the Hubble tension, remains one of the most pressing open questions in co…

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…

Robust parameter inference for Taiji via time-frequency contrastive learning and normalizing flows

Tian-Yang Sun, Bo Liang, Ji-Yu Song +6

Transient noise artifacts, commonly referred to as glitches, pose a major challenge to parameter inference for space-based gravitational-wave (GW) observations. We develop a glitch…

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…

Bounding the number of spacetime dimensions from precessing black hole binaries with the third-generation gravitational-wave detectors

Xu-Jie Zhu, Ji-Yu Song, Tao Zhu +1

In the theories with extra dimensions, gravitational waves can leak into extra dimensions, resulting in a reduction in the amplitude of the observed gravitational waves. Such an ef…
