Scalar scattering by black holes and wormholes
Haroldo C. D. Lima Junior, Carolina L. Benone, Luís C. B. Crispino
We study the scattering of monochromatic planar scalar waves in a geometry that interpolates between the Schwarzschild solution, regular black holes and traversable wormhole spacet…
Shadows and lensing of black holes immersed in strong magnetic fields
Haroldo C. D. Lima Junior, Pedro V. P. Cunha, Carlos A. R. Herdeiro +1
We investigate the null geodesic flow and in particular the light rings (LRs), fundamental photon orbits (FPOs) and shadows of a black hole (BH) immersed in a strong, uniform magne…
4D Einstein-Gauss-Bonnet gravity: Massless particles and absorption of planar spin-0 waves
Haroldo C. D. Lima Junior, Carolina L. Benone, Luís C. B. Crispino
We investigate the absorption cross section of planar scalar massless waves impinging on spherically symmetric black holes which are solutions of the novel 4D Einstein-Gauss-Bonnet…
Spinning black holes with a separable Hamilton-Jacobi equation from a modified Newman-Janis algorithm
Haroldo C. D. Lima Junior, Luís C. B. Crispino, Pedro V. P. Cunha +1
Obtaining solutions of the Einstein field equations describing spinning compact bodies is typically challenging. The Newman-Janis algorithm provides a procedure to obtain rotating…
Scalar absorption: Black holes versus wormholes
Haroldo C. D. Lima Junior, Carolina L. Benone, Luís C. B. Crispino
We study the absorption of massless scalar waves in a geometry that interpolates between the Schwarzschild solution and a wormhole that belongs to the Morris-Thorne class of soluti…
