Scattering by stringy black holes
Sérgio V. M. C. B. Xavier, Carolina L. Benone, Luiz C. S. Leite +1
We study the scattering of axially incident massless scalar waves by a charged and rotating black hole solution from heterotic string theory called the Kerr-Sen black hole. We comp…
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…
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…
Analytical investigation of wave absorption by a rotating black hole analogue
Leandro A. Oliveira, Carolina L. Benone, Amanda L. Almeida +1
Perturbations in a draining vortex can be described analytically in terms of confluent Heun functions. In the context of analogue models of gravity in ideal fluids, we investigate…
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…
Black holes with synchronised Proca hair: linear clouds and fundamental non-linear solutions
Nuno M. Santos, Carolina L. Benone, Luís C. B. Crispino +2
Recent studies have made key progress on the black hole/solitonic solutions of the Einstein-Proca system. Firstly, fully non-linear dynamical evolutions of the Kerr black hole supe…
