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…

Generalized black-bounces solutions in f(R) gravity and their field sources
Marcos V. de S. Silva, T. M. Crispim, G. Alencar +2
In this work, following our recent findings in [1], we extend our analysis to explore the generalization of spherically symmetric and static black-bounce solutions, known from Gene…

Field Sources for Wormholes With Multiple Throats/Anti-throats
T. M. Crispim, Marcos V. de S. Silva, G. Alencar +2
In this work, we investigate wormhole geometries with multiple throats and anti-throats in general relativity. The existence of these structures is identified through the analysis…
