Absorption and (unbounded) superradiance in a static regular black hole spacetime
Marco A. A. de Paula, Luiz C. S. Leite, Sam R. Dolan +1
Regular black holes (RBHs) -- geometries free from curvature singularities -- arise naturally in theories of non linear electrodynamics. Here we study the absorption, and superradi…
Electrically charged regular black holes in nonlinear electrodynamics: light rings, shadows and gravitational lensing
Marco A. A. de Paula, Haroldo C. D. Lima Junior, Pedro V. P. Cunha +1
Within nonlinear electrodynamics (NED), photons follow null geodesics of an effective geometry, which is different from the geometry of the spacetime itself. Over the last years, s…
Scattering properties of charged black holes in nonlinear and Maxwell's electrodynamics
Marco A. A. de Paula, Luiz C. S. Leite, Luís C. B. Crispino
We investigate the scattering properties of a massless scalar field in the background of a charged Ayón-Beato-García regular black hole solution. Using a numerical approach, we com…
