From massless wormholes to massive black bounces: Shadows and multiple light rings
G. Alencar, Kirill A. Bronnikov, T. M. Crispim +2
We develop a general framework for constructing massive black bounce geometries from massless wormhole seeds by introducing a position-dependent mass function while preserving the…
Field Sources for Wormholes With Multiple Throats/Anti-throats
T. M. Crispim, Marcos V. de S. Silva, G. Alencar +2
In this work, we investigate wormhole geometries with multiple throats and anti-throats in general relativity. The existence of these structures is identified through the analysis…
Exponential gravity with logarithmic corrections in the presence of axion dark matter
Sergei D. Odintsov, Diego Sáez-Chillón Gómez, German S. Sharov
An exponential modified gravity with additional logarithmic corrections is considered with the presence of an axion-like scalar field in the role of dark matter. Axion fields are t…
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…
Exponential F(R) gravity with axion dark matter
Sergei D. Odintsov, Diego Sáez-Chillón Gómez, German S. Sharov
The cosmological evolution within the framework of exponential gravity is analysed by assuming two forms for dark matter: (a) a standard dust-like fluid and (b) an axion sca…
Regularizing Rotating Black Strings: a new black bounce solution
A. Lima, G. Alencar, Diego Sáez-Chillon Gómez
The present paper is devoted to a new black bounce solution that regularize the well-known rotating black string in dimensions. To do so, the procedure pointed out by Simpson…
