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…
Black-bounce solutions in a k-essence theory under the effects of bumblebee gravity
Carlos F. S. Pereira, Marcos V. de S. Silva, H. Belich +3
In the present study, we analyze the effects of violation of Lorentz symmetry for black-bounce solutions in a -essence theory that has the form of a power law for the configurat…
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…
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 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…
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,…
Orbits around a black bounce spacetime
Marcos V. de S. Silva, Manuel E. Rodrigues
In this work, the trajectories of particles around a black bounce spacetime are considered, with the Simpson-Visser model serving as an example. Trajectories for massless and massi…
On black bounce space-times in non-linear electrodynamics
G. Alencar, Kirill A. Bronnikov, Manuel E. Rodrigues +2
One of the main issues in gravitation is the presence of singularities in the most common space-time solutions of General Relativity, as the case of black holes. A way of construct…
Comment on "Source of black bounces in Rastall gravity''
Manuel E. Rodrigues, Marcos V. de S. Silva
In Atazadeh and Hadi (JCAP \textbf{01}, 067 (2024)), the authors proposed that black bounce solutions, such as the Simpson-Visser and the Bardeen-type spacetimes, can be obtained f…
