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…
Near-Horizon Deformation of Metric and the Black Hole Instability
Shi-Jie Ma, Zhan-Feng Mai, Run-Qiu Yang
Recent time-domain analyses suggest that black hole stability may be sensitive to localized near-horizon geometric deformations, while the underlying spectral mechanism remains unc…
Shadows and photon spheres of static black holes embedded in a Dehnen-(1,4,5/2)-type dark matter halo with a quintessential field
Hong-Er Gong, Junlin Qin, Yusen Wang +4
This paper investigates the appearance characteristics of static black holes embedded in Dehnen-(1,4,5/2)-type dark matter halos with a quintessential field, focusing on how the da…
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…
Shadow and Optical Imaging in Einstein-Maxwell-Dilaton Black Hole
Junlin Qin, Hong-Er Gong, Yusen Wang +4
This paper investigates photon motion in black hole of Einstein-Maxwell-dilaton theory, exploring black hole shadows and observational characteristics under various accretion model…
