Absorption and scattering spectra of massive scalar waves in charged regular black hole spacetimes
Marco A. A. Paula, Carolina L. Benone, Luís 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…
Interaction of the gravitational Hawking radiation and a static point mass
João P. B. Brito, Atsushi Higuchi, Luís C. B. Crispino
We study the interaction of a stress-energy tensor describing a static point mass supported by a string outside a Schwarzschild black hole with the gravitons of the Hawking radiati…
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
One of the main features of nonlinear electrodynamics is the existence of an effective geometry that describes the geodesic motion of photons. A detailed analysis of the properties…
