Gravitational Lensing by Black Holes in Einstein-nonlinear Electrodynamic Theories with Multiple Photon Spheres
Siyuan Hui, Benrong Mu, Peng Wang
In this paper, we study the gravitational lensing effects of non-linear electrodynamic black holes. Non-linear electrodynamic black holes serve as typical models for multi-event ho…

Schwarzschild Black Holes Immersed in Born-Infeld Magnetic Fields and Their Observational Signatures
Yiqian Chen, Guangzhou Guo, Benrong Mu +1
We investigate the influence of Born-Infeld (BI) nonlinear electrodynamics on magnetic field configurations, photon orbits, and black hole shadows for Schwarzschild black holes imm…

Quasinormal modes of Schwarzschild-like black hole surrounded by the pseudo-isothermal dark matter halo
Yanqiang Liu, Benrong Mu, Jun Tao +1
The merger of binary black holes produces a series of decaying oscillations, during which energy is radiated in gravitational waves. The characteristic signal in the ringdown phase…
