An agentic framework for gravitational-wave counterpart association in the multi-messenger era
Yiming Dong, Yacheng Kang, Junjie Zhao +3
With the detection of gravitational waves (GWs), multi-messenger astronomy has opened a new window for advancing our understanding of astrophysics, dense matter, gravitation, and c…
Cracking Gravitational Wave Multiple Ringdown Modes in Space
Ziming Wang, Han Wang, Yuxin Yang +4
Ringdown signals from perturbed black holes (BHs) offer a clean window into BH spacetime, strong-field gravity, and fundamental physics. Presently the quasi-normal modes of stellar…
Inferring neutron-star Love-Q relations from gravitational waves in the hierarchical Bayesian framework
Zhihao Zheng, Ziming Wang, Jinwen Deng +2
Despite the large uncertainties in the equation of state for neutron stars (NSs), a tight universal ``Love-Q'' relation exists between their dimensionless tidal deformability, …
Multiple Components and Spectral Evolution of BL Lacertae as Revealed by Multiwavelength Variability and SED Modeling
Hanxiao Xia, Ziming Wang, Jianghua Wu +2
BL Lac has entered an active state since 2020, with multiwavelength observations revealing intense flares. In this study, we conducted 12-night multicolor optical monitoring using…
A Realistic Pulsar -- Supermassive Black Hole Timing Model
Zexin Hu, Ziming Wang, Lijing Shao
Timing observation of pulsars orbiting around a supermassive black hole (SMBH) can measure the spacetime around the SMBH to a high precision and thus be a novel probe of the gravit…
Anatomy of parameter-estimation biases in overlapping gravitational-wave signals: detector network
Ziming Wang, Dicong Liang, Lijing Shao
With the significantly improved sensitivity and a wider frequency band, the next-generation gravitational-wave (GW) detectors are anticipated to detect GW signals per y…
