Thermodynamics of rotating black holes with constrained primary hair
Wentao Liu, Di Wu, Shao-Wen Wei +1
An exact rotating geometry need not define a black hole in equilibrium when its surface gravity varies across the horizon. We construct an asymptotically flat, non-Kerr subfamily o…
Macroscopic Optical Nonreciprocity: A Black Hole as an Optical Diode
Wentao Liu, Di Wu, Xiongjun Fang +2
Optical reciprocity--the principle that light retraces the same path when source and detector are interchanged--is a foundational concept in geometric optics. In this Letter, we de…
A Universal Framework for Horizon-Scale Tests of Gravity with Black Hole Shadows
Wentao Liu, Yang Liu, Di Wu +1
In this Letter, we have developed a numerically efficient framework for evaluating parameters in metric theories of gravity, and applied it to constrain the horizon-scale magnetic…
Lorentz violation signatures in the low-energy sector of Hořava gravity from black hole shadow observations
Wentao Liu, Hongxia Huang, Di Wu +1
In this paper, we use the Hořava gravity model and EHT observations of supermassive black holes (BHs) to investigate signatures of Lorentz violation in real astrophysical environme…
Light rings and shadows of static black holes in effective quantum gravity II: A new solution without Cauchy horizons
Wentao Liu, Di Wu, Jieci Wang
Among the three known types of static solutions proposed within the Hamiltonian constraint approach to effective quantum gravity (EQG), the first two have been extensively investig…
Universal thermodynamic topological classes of rotating black holes
Xiao-Dan Zhu, Wentao Liu, Di Wu
In a recent study, Wei et al. [Phys. Rev. D 110, L081501 (2024)] proposed a universal classification scheme that interprets black hole solutions as topological defects within the t…
Thermodynamic topological classes of the rotating, accelerating black holes
Wentao Liu, Li Zhang, Di Wu +1
In this paper, we investigate the topological numbers for the rotating, accelerating neutral black hole and its AdS extension, as well as the rotating, accelerating charged black h…
Light rings and shadows of static black holes in effective quantum gravity
Wentao Liu, Di Wu, Jieci Wang
Recently, two types of static black hole models that retain general covariance have been proposed within the Hamiltonian constraint approach to effective quantum gravity (EQG). We…
Kerr-MOG-(A)dS black hole and its shadow in scalar-tensor-vector gravity theory
Wentao Liu, Di Wu, Xiongjun Fang +2
The scalar-tensor-vector gravity (STVG) theory has attracted significant interest due to its ability to effectively address the issue of galaxy rotation curves and clusters of gala…
Shadow of slowly rotating Kalb-Ramond black holes
Wentao Liu, Di Wu, Jieci Wang
Real astronomical objects possess spin, yet deriving exact solutions for rotating black holes within gravitational theories is a formidable challenge. To understand the shadow of r…
Static neutral black holes in Kalb-Ramond gravity
Wentao Liu, Di Wu, Jieci Wang
The Kalb-Ramond (KR) gravity theory, a modified gravity theory that nonminimally couples a KR field with a nonzero vacuum expectation value for the gravitational field, can spontan…
