Resonant bound orbits and kludge waveforms in rotating Konoplya-Zhidenko black hole spacetime
Qiyu Dai, Xiongjun Fang, Xiao-Mei Kuang +1
We investigate timelike bound motion, resonant periodic orbits, and their gravitational-wave signatures in the rotating Konoplya-Zhidenko (KZ) black hole spacetime. Using the separ…
Detecting Lorentz-violation induced by a tensor field with S-star's motion around Sgr A*
Qi Qi, Yu Sang, Xiao-Mei Kuang
Testing Lorentz symmetry in strong gravitational fields provides a unique probe of extensions to standard model. The orbiting motions of the S-stars around the supermassive black h…
Probing a Lorentz-violating parameter from orbital precession of the S2 star around the galactic centre supermassive black hole
Qi Qi, Yu Sang, Xiao-Mei Kuang
Testing Lorentz symmetry in strong gravitational fields provides a promising probe of extensions to general relativity. The supermassive black hole Sgr~A* and the orbit of the S-st…
Geodesic dynamics and multi-inclination images of a non-minimally coupled black hole with a thin accretion disk
Tian-Yu Chen, Yong-Zhuang Li, Xiao-Mei Kuang
In this paper, we investigate the optical properties of a black hole in non-minimal Einstein-Yang-Mills theory, illuminated by a thin accretion disk. In our setup, matter follows s…
The bound orbits and gravitational waveforms of timelike particles around renormalization group improved Kerr black holes
Yong-Zhuang Li, Xiao-Mei Kuang
In this article, we investigate the bound orbits of the timelike particles and the gravitational waveforms emitted from these orbits around a renormalization group improved Kerr bl…
The shadow and quasinormal modes of the asymptotically flat hairy black holes with a dilaton potential
Sheng-Han Xiong, Yong-Zhuang Li, Xiao-Mei Kuang +1
In this article, the shadow and the quasinormal modes (QNMs) of an exact asymptotically flat hairy electrically charged black hole solution with a dilaton potential are investigate…
Effects of hair on the image of a rotating black hole illuminated by a thin accretion disk
Yuan Meng, Xi-Jing Wang, Yong-Zhuang Li +1
In this paper, we investigate the shadow and optical appearance of the hairy Kerr black hole illuminated by a thin accretion disk, the materials of which outside the innermost stab…
Timelike bound orbits and pericenter precession around black hole with conformally coupled scalar hair
Qi Qi, Xiao-Mei Kuang, Yong-Zhuang Li +1
We investigate the geodesic motions of timelike particles around a static hairy black hole with conformally coupled scalar field. We mainly focus on the effects of the scalar charg…
Precessing and periodic timelike orbits and their potential applications in Einsteinian cubic gravity
Yong-Zhuang Li, Xiao-Mei Kuang
Einsteinian cubic gravity (ECG) is the most general theory up to cubic order in curvature, which have the same graviton spectrum as the Einstein theory. In this paper, we investiga…
Trajectories of photons around a rotating black hole with unusual asymptotics
Yong-Zhuang Li, Xiao-Mei Kuang
Most black hole solutions are characterized with asymptotically flat, or asymptotically (anti) de-Sitter behaviors, but some black holes with unusual asymptotics have also been con…
