Accuracy of source localization for eccentric inspiraling binary mergers using a ground-based detector network
Hsing-Po Pan, Chun-Yu Lin, Zhoujian Cao +1
The problem of gravitational wave parameter estimation and source localization is crucial in gravitational wave astronomy. Gravitational waves emitted by compact binary coalescence…
Static charged Gauss-Bonnet black holes cannot be overcharged by the new version of gedanken experiments
Jie Jiang
Based on the new version of the gedanken experiments proposed by Sorce and Wald, we examine the weak cosmic censorship conjecture (WCCC) under the spherically charged infalling mat…
Quantization of the nonstandard propagating gravitational waves in the cosmological background
S. X. Tian, Zong-Hong Zhu
Detections of gravitational wave (GW) stimulate the discussion of how GWs propagate in the expanding Universe. General relativity predicts that GWs are massless and propagate at th…
On the Size of a Black Hole: The Schwarzschild is the Biggest
H. Lu, Hong-Da Lyu
We consider static black holes in Einstein gravity and study parameters characterizing the black hole size, namely the radii of the horizon , photon sphere and bl…
Observational signature of a near-extremal Kerr-Sen black hole in the heterotic string theory
Minyong Guo, Shupeng Song, Haopeng Yan
We analytically study the optical appearance of an isotropically emitter orbiting near the horizon of a near-extremely rotating Kerr-Sen (KS) black hole which is an electrically ch…
Relativistic Mean Motion Resonance
Huan Yang, Béatrice Bonga, Zhipeng Peng +1
Mean motion resonances are commonly seen in planetary systems, e.g., in the formation of orbital structure of Jupiter's moons and the gaps in the rings of Saturn. In this work we s…
Constraint on the fifth force through perihelion precession of planets
Bing Sun, Zhoujian Cao, Lijing Shao
The equivalence principle is important in fundamental physics. The fifth force, as a describing formalism of the equivalence principle, may indicate the property of an unknown theo…
The fastest relaxation rate of higher-dimensional Reissner--Nordström black hole
Ming Zhang, Jie Jiang, Zhen Zhong
In the eikonal regime, we analytically calculate quasinormal resonance frequencies for massless scalar perturbations of the higher-dimensional Reissner--Nordström (RN) black holes.…
Validating the Effective-One-Body Numerical-Relativity Waveform Models for Spin-aligned Binary Black Holes along Eccentric Orbits
Xiaolin Liu, Zhoujian Cao, Lijing Shao
Effective-one-body (EOB) numerical-relativity (NR) waveform models for spin-aligned binary black holes (BBHs), known as the SEOBNR waveform models, are based on the EOB theoretical…
Information paradox and corrected thermodynamics for black holes
Ming Zhang
We generally consider that entropy and temperature of a spherically symmetric black hole are corrected by quantum effect. We calculate interior entropy variation of massless scalar…
Alternative route towards the change of metric signature
Fan Zhang
Beginning with Hartle and Hawking's no-boundary proposal, it has long been known that the pathology of a big bang singularity can be suppressed if a transition into Riemannian (Euc…
Scalar, Vector and Tensor Harmonics on the Flat Compact Orientable Three-Manifolds
Zhi-Peng Peng, Lee Lindblom, Fan Zhang
Observations suggest that our universe is spatially flat on the largest observable scales. Exactly six different compact orientable three-dimensional manifolds admit flat metrics.…

Hyat Huang, Jinbo Yang
By replacing the scalar with in the solution constructed in Ref\cite{Huang:2019lsl}, we obtain electrically-charged wormhole and black hole solutions in the Einstein-Maxwe…
Testing the Schwarzschild metric in a strong field region with the Event Horizon Telescope
S. X. Tian, Zong-Hong Zhu
Testing gravity theory in the strong field region becomes a reality due to the observations of gravitational waves and black hole shadows. In this paper, we discuss how to constrai…

Yi Gong, Zhoujian Cao, He Gao +1
For non-spinning, charged (Reissner-Nordström) black holes, the particles with an opposite sign of charge with respect to that of the black hole will be pulled into the black hole…

Yizhou Lu, Yungui Gong, Zhu Yi +1
Primordial black holes and secondary gravitational waves can be used to probe the small scale physics at very early time. For secondary gravitational waves produced after the horiz…

Junjie Zhao, Lijing Shao, Zhoujian Cao +1
We investigate the scalar-tensor gravity of Damour and Esposito-Farèse (DEF), which predicts non-trivial phenomena in the nonperturbative strong-field regime for neutron stars (NSs…
