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…
LQG inspired spacetimes as solutions of the Einstein equations
Marcos V. de S. Silva, Carlos F. S. Pereira, G. Alencar +1
Black bounces are compact objects with a wormhole structure hidden behind an event horizon. This type of metric can be obtained through general relativity by considering the presen…
Field Sources for Black-Bounce Solutions: The Case of K-Gravity
G. Alencar, M. Nilton, Manuel E. Rodrigues +1
In the framework of Simpson-Visser, the search for field sources that produce black-bounces in alternative gravity theories has remained unresolved. In this paper, the first in a s…
Spherically symmetric and static black bounces with multiple horizons, throats, and anti-throats in four dimensions
Manuel E. Rodrigues, Marcos V. de S. Silva
Black bounce spacetimes usually arise from the Simpson-Visser regularization method. This type of metric presents a wormhole throat inside an event horizon. In this paper, we prese…
