Frequency Shifts of photons emitted from geodesics of nonlinear electromagnetic black holes
L. A. López, J. C. Olvera
We analyzed the frequency shifts of photons emitted from massive particles that move in stable geodesics around black holes with non-linear electrodynamics. The motion of the photo…

Absorption section for black holes surrounded by scalar fields
José Carlos Olvera
The absorption section of black holes surrounded by scalar fields is studied with the sinc approximation in the eikonal limit. The effects of the scalar field on the nonlinear Eule…

Scattering and absorption sections of nonlinear electromagnetic black holes
J. C. Olvera, L. A. López
The expression of the impact parameter, in the analysis for classical and semiclassical scattering cross sections for black holes, is obtained with nonlinear electrodynamics (NLED)…
