Traversable double-throat wormholes in a string cloud background
Yvens Amaral, M. S. Cunha, C. R. Muniz +1
This work constructs a new class of traversable wormhole solutions with a double-throat topology, modeled as a localized perturbation of the Ellis-Bronnikov metric in a string clou…
Traversable wormholes from a smoothed string fluid in 4D Einstein-Gauss-Bonnet gravity
C. R. Muniz, M. S. Cunha, L. C. N. Santos
We investigate traversable wormhole solutions in four-dimensional Einstein-Gauss-Bonnet (EGB) gravity sourced by a smoothed string fluid. Originally proposed to model regular black…
Black holes inside cosmic voids
Francisco Bento Lustosa, Milko Estrada, Marcony S. Cunha +1
This study examines the gravitational and thermodynamic properties of static, spherically symmetric black holes within cosmic voids -- vast underdense regions of the universe. By d…
Five dimensional rotating and Quintessence black hole and their hypershadows
Milko Estrada, L. C. N. Santos, M. S. Cunha
We present a new five-dimensional rotating quintessence black hole solution. To obtain this, we employ the version of the Janis Newman algorithm, which incorporates the Hopf b…
