Sources of matter for wormholes in a k-essence theory
Marcos V. de S. Silva, Carlos F. S. Pereira, Bruna Bragato +3
The paper investigates wormhole solutions in a k‑essence theory coupled to a phantom scalar field, deriving the scalar field, potential, and electromagnetic functions for electrica…
Light propagation and gravitational lensing effects in charged Kalb-Ramond spacetime in nonlinear electrodynamics
C. F. S. Pereira, Marcos V. de S. Silva, A. R. Soares +3
In this work, we theoretically investigate the deflection of light for strong- and weak-field regimes in the background of an electrically charged BH described in Kalb-Ramond gravi…
Light propagation and quasinormal modes of a topologically charged Schwarzschild-Klinkhamer wormhole
C. F. S. Pereira, H. Belich, A. R. Soares +3
In this work, we present a theoretical analysis of null geodesics, critical photon orbits, and shadow formation associated with a wormhole generated by a geometric defect. The prop…
Light deflection and gravitational lensing effects inspired by loop quantum gravity
A. R. Soares, C. F. S. Pereira, R. L. L. Vitória +2
In the present work, we theoretically investigate light deflection in the weak and strong field regimes for two regular spacetimes with corrections from loop quantum gravity. We tr…
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…
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,…
