Scattering of charged massive scalar waves by Kerr-Newman black holes
Qian Li, Qianchuan Wang, Junji Jia
The scattering of charged massive scalar waves by Kerr-Newman black holes, with incidence along the equatorial plane, is investigated in this work. The differential scattering cros…
On-axis absorption and scattering of charged massive scalar waves by Kerr-Newman black-bounce spacetime
Qian Li, Qianchuan Wang, Junji Jia
We investigate the absorption and scattering of charged massive scalar waves by the Kerr-Newman black-bounce spacetime when the waves are incident along the rotation axis. Our find…
Weak deflection angle of charged signal in magnetic fields
Qianchuan Wang, Junji Jia
We use the perturbative method to study the influence of the magnetic field on the weak deflection angle of charged signals in magnetized stationary and axisymmetric spacetimes wit…
Absorption and scattering of charged scalar waves by charged Horndeski black hole
Qian Li, Qianchuan Wang, Junji Jia
We investigate the absorption and scattering of a charged massive scalar field by a charged Horndeski black hole using both the approximation or classical geometric method and the…
Periapsis shift in spherically symmetric spacetimes and effect of electric interaction
Qianchuan Wang, Junji Jia
The periapsis shift of charged test particles in arbitrary static and spherically symmetric charged spacetimes are studied. Two perturbative methods, the near-circular approximatio…
Deflection in higher dimensional spacetime and asymptotically non-flat spacetimes
Jinhong He, Qianchuan Wang, Qiyue Hu +2
Using a perturbative technique, in this work we study the deflection of null and timelike signals in the extended Einstein-Maxwell spacetime, the Born-Infeld gravity and the charge…
