Superradiant scattering by rotating black-bounce black holes
Pedro Henrique Croti Siqueira, Maurício Richartz
We investigate superradiant scattering off a rotating regular black hole described by a black-bounce metric which generalizes the Kerr spacetime of mass and specific angular mo…
Pseudospectrum of rotating analog black holes
Lucas Tobias de Paula, Pedro Henrique Croti Siqueira, Rodrigo Panosso Macedo +1
Analyzing the stability of quasinormal modes (QNM) is essential for understanding black hole dynamics, particularly in the context of gravitational wave emissions and black hole sp…
Probing the Unstable Spectrum of Schwarzschild-like Black Holes
Pedro Henrique Croti Siqueira, Lucas Tobias de Paula, Rodrigo Panosso Macedo +1
We investigate the pseudospectrum of a Schwarzschild-like spacetime within the framework of black hole perturbation theory to analyze a counterintuitive assertion regarding the ins…
Quasinormal modes, quasibound states, scalar clouds, and superradiant instabilities of a Kerr-like black hole
Pedro Henrique Croti Siqueira, Maurício Richartz
We use the continued fraction method to determine the eigenfrequencies associated with a scalar field around a Kerr-like black hole. The Kerr-like metric considered in this article…
