Light propagation and gravitational lensing effects in charged Kalb-Ramond spacetime in nonlinear electrodynamics
C. F. S. Pereira, Marcos V. de S. Silva, A. R. Soares +3
In this work, we theoretically investigate the deflection of light for strong- and weak-field regimes in the background of an electrically charged BH described in Kalb-Ramond gravi…

Light propagation and quasinormal modes of a topologically charged Schwarzschild-Klinkhamer wormhole
C. F. S. Pereira, H. Belich, A. R. Soares +3
In this work, we present a theoretical analysis of null geodesics, critical photon orbits, and shadow formation associated with a wormhole generated by a geometric defect. The prop…
