Ensemble-Based Residual Tests of GW231123 across Waveform Models
Dicong Liang, Hai-Tian Wang, Junlin Qin +3
GW231123 is an exceptional gravitational wave event for which different waveform models yield significantly different inferred source parameters. Residual tests provide a direct wa…
Asymptotically-flat Black holes in Bumblebee gravity: Exact solutions and Thermodynamics
Jinbo Yang, Zhan-Feng Mai, Dicong Liang +1
We construct analytic solutions to the bumblebee gravity theory in static and spherically symmetric spacetimes, where the bumblebee vector field admits only a non-vanishing tempora…
Residual Test for the Third Gravitational-Wave Transient Catalog
Dicong Liang, Ning Dai, Yingjie Yang
The residual test is commonly used to check the agreement between the gravitational wave signal and the theoretical waveform template. The basic idea of the residual test is to sub…
The stealth Kerr solution in the bumblebee gravity
Rui Xu, Zhan-Feng Mai, Dicong Liang
In this paper, we find Kerr solution accompanied with a nontrivial vector field as a solution to one of the simplest vector-tensor theories of gravity, namely the bumblebee model w…
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…
Constraining Fermionic Dark Matter with Galactic Neutron Stars
Jianyuan Luo, Dicong Liang, Lijing Shao
Dark matter (DM) remains one of the most significant open questions in modern physics, with its nature and interactions largely unexplored. In this study, we investigate the behavi…
