Gravitational Lensing in a Kasner Background: Distinguishing Wormholes and Black Holes
Celio R. Muniz, Jonathan A. Rebouças, M. B. Cruz +1
We investigate gravitational lensing by compact objects embedded in anisotropic Bianchi-I cosmologies using directional Jacobi maps within the thin-lens approximation. The formalis…
Distinguishing wormholes via Einstein rings and global curvature
M. B. Cruz, C. R. Muniz, R. M. P. Neves +1
In this work, we investigate the gravitational lensing properties of a static Ellis-Bronnikov wormhole embedded in a curved Friedmann-Lemaître-Robertson-Walker (FLRW) universe. By…
Traversable Wormholes Sourced by Dark Matter in Loop Quantum Cosmology
Marcos V. de S. Silva, G. Alencar, R. N. Costa Filho +2
In this work, we investigate the existence of wormholes within the framework of Loop Quantum Cosmology, using isotropic dark matter as the source. We analyze three distinct density…
Hot Casimir wormholes in Einstein-Gauss-Bonnet gravity
C. R. Muniz, M. B. Cruz, R. M. P. Neves +2
In this work, we explore the thermal effects on Casimir wormholes in the context of higher-dimensional Einstein-Gauss-Bonnet gravity. Motivated by the fundamental role of EGB gravi…
Probing the Solar System for Dark Matter Using the Sagnac Effect
A. D. S. Souza, C. R. Muniz, R. M. P. Neves +1
This study investigates the potential of the Sagnac Effect for detecting dark matter in the Solar System, particularly within the Sun. Originating from the relative delay and inter…
