Three dimensional black bounces in gravity
Marcos V. de S. Silva, Manuel E. Rodrigues, C. F. S. Pereira
We investigate the existence of black bounce solutions in dimensions within the framework of gravity. We analyze whether black bounce geometries originally obtained in…
Sources of matter for wormholes in a k-essence theory
Marcos V. de S. Silva, Carlos F. S. Pereira, Bruna Bragato +3
In this work, we analyze some matter sources associated with wormhole models within a k-essence theory coupled to the gravitational sector through a phantom scalar field. We adopt…
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…
Magnetically charged black-bounce solution via nonlinear electrodynamics in a k-essence theory
Carlos F. S. Pereira, Denis C. Rodrigues, Marcos V. de S. Silva +3
In the present work, we obtain and analyze a new class of analytical solutions of magnetically charged black bounces in k-essence theory, spherically symmetric in (3+1)-dimensions,…
New sources of ghost fields in -essence theories for black-bounce solutions
Carlos F. S. Pereira, Ébano L. Martins, Denis C. Rodrigues +2
In the present study, we generalize the possible ghost field configurations within the framework of -essence theory to the Simpson-Visser metric area function . Our…
Black-bounce solution in -essence theories
Carlos F. S. Pereira, Denis C. Rodrigues, Júlio C. Fabris +1
In the present work, we construct black-bounce configurations in the context of -essence theory. The solutions have a regular metric function at the origin. The area metric func…
