Non-stationary wormholes with the presence of scalar fields and modified gravity
G. Alencar, R. Dárlla, Shin'ichi Nojiri +2
Some novel regular spacetimes are considered that show a non-stationary wormhole structure. A Simpson-Visser-like procedure is applied to reconstruct these regular spacetimes, free…
Shadows from thin accretion disks of parametrized black hole solutions
Gonzalo J. Olmo, João Luís Rosa, Diego Rubiera-Garcia +2
We discuss the optical appearance from thin accretion disks in parametrized black holes, namely, solutions characterized by an arbitrarily large number of parameters without any re…
Tidal Stretching and Compression in Black Bounce Backgrounds
T. M. Crispim, Marcos V. de S. Silva, G. Alencar +1
Black bounces are compact objects that combine the structures of regular black holes with those of wormholes. These spacetimes exhibit a rich causal structure and can differ fundam…
Quasi-normal modes and echoes of generalized black hole bounces and their correspondence with shadows
Albert Duran-Cabacés, Diego Rubiera-Garcia, Diego Sáez-Chillón Gómez
We study the quasi-normal modes (QNMs) of a family of generalized black bounces interpolating between regular black holes and traversable wormhole solutions according to a single e…
