Gravitational lensing by a black hole with torsion
Lu Zhang, Songbai Chen, Jiliang Jing
In this paper we have investigated the gravitational lensing in a spherically symmetric spacetime with torsion in the generalized Einstein-Cartan-Kibble-Sciama (ECKS) theory of gra…
Repulsive effect for the unbound high energy particles along the rotation axis in the Kerr-Taub-NUT spacetime
Lu Zhang, Songbai Chen, Jiliang Jing
We have investigated the acceleration of the unbound high energy particles moving along the rotation axis in the Kerr-Taub-NUT spacetime, and then study the dependence of the repul…
Shadows of Bonnor black dihole by chaotic lensing
Mingzhi Wang, Songbai Chen, Jiliang Jing
We have studied numerically the shadows of Bonnor black dihole through the technique of backward ray-tracing. The presence of magnetic dipole yields non-integrable photon motion, w…
Energy extraction from a Konoplya-Zhidenko rotating non-Kerr black hole
Fen Long, Songbai Chen, Shangyun Wang +1
We have investigated the properties of the ergosphere and the energy extraction by Penrose process in a Konoplya-Zhidenko rotating non-Kerr black hole spacetime. We find that the e…
Shadow casted by a Konoplya-Zhidenko rotating non-Kerr black hole
Mingzhi Wang, Songbai Chen, Jiliang Jing
We have investigated the shadow of a Konoplya-Zhidenko rotating non-Kerr black hole with an extra deformation parameter. The spacetime structure arising from the deformed parameter…
Detect black holes using photons for coupling model of electromagnetic and gravitational fields
Jiliang Jing, Songbai Chen, Qiyuan Pan +1
For a model of the electromagnetic field coupled to Weyl tensor, Maxwell equations are modified and photons at low frequencies no longer propagate along light cone. If we detect a…
