Probing nonlinear electrodynamics-sourced black holes via light and orbital mechanics
Marco A. A. de Paula, Ednaldo L. B. Junior
Well-founded models of nonlinear electrodynamics (NED) are typically characterized by an additional parameter associated with their deviation from linear electrodynamics. In additi…
Absorption spectrum and greybody factors of charged black holes in loop quantum gravity
Marco A. A. de Paula, Valdir B. Bezerra, Luiz C. S. Leite
In the last few decades, singularity-free black holes (BHs) obtained in the framework of Loop Quantum Gravity (LQG) have gained attention in the literature. These compact objects r…
Two shadows of a single black hole: Vacuum birefringence phenomena within Einstein-nonlinear-electrodynamics
Marco A. A. de Paula, Haroldo C. D. Lima, Pedro V. P. Cunha +2
The paper investigates photon propagation in black holes sourced by a nonlinear electrodynamics model, showing that vacuum birefringence leads to two distinct photon trajectories a…
Absorption and scattering spectra of massive scalar waves in charged regular black hole spacetimes
Marco A. A. Paula, Carolina L. Benone, LuÃs C. B. Crispino
Regular black holes (RBHs) can be seen as possible alternatives to standard black holes (BHs), since these geometries do not have a curvature singularity. As a way of improving our…
Exploring potential astrophysical applications of black holes in nonlinear electrodynamics
Marco A. A. de Paula, Mustapha Azreg-Aïnou
Spacetimes arising from nonlinear electrodynamics (NED) are a good laboratory for studying both the nature of regular black holes (RBH) solutions and the imprints of nonlinear elec…
