Vacuum breakdown in a misaligned magnetized Kerr spacetime
Ruixin Yang, Songbai Chen, Jiliang Jing
Electron-positron () pair creation by vacuum breakdown around compact objects is believed to power high-energy astrophysical transients like gamma-ray bursts (GRBs). In…
Shadow of a circular disformal Kerr black hole beyond GR
Fen Long, Songbai Chen, Jiliang Jing
We have studied the shadows of a circular disformal Kerr black hole with a deformation parameter, which represents a rotating solution within a generalized scalar-tensor framework…
Polarized image of an equatorial emitting ring around a Konoplya-Zhidenko rotating non-Kerr black hole
Xin Qin, Fen Long, Songbai Chen +1
We investigate the polarized images of an equatorial emitting ring around a Konoplya-Zhidenko rotating non-Kerr black hole, which introduces an additional deformation parameter. Th…
Chaotic motion of particles around a dyonic Kerr-Newman black hole immersed in the Melvin-swirling universe
Deshui Cao, Lina Zhang, Songbai Chen +2
We employ the Poincaré section, fast Lyapunov indicator, recurrence analysis, bifurcation diagram and basins of attraction to investigate the dynamical behaviors of the motion of p…
Effects of tidal charge on Blandford-Znajek process around braneworld black holes
Ruixin Yang, Songbai Chen, Jiliang Jing
The Blandford-Znajek (BZ) process is a pivotal mechanism to efficiently extract the energy from a rotating black hole (BH) via its plasma-filled magnetosphere in relativistic astro…
