An Analytical Two Incompressible Fluid Star with a Mixed Ordinary Dark Matter Core and an Ordinary Matter Envelope
Milko Estrada, Santiago Esteban Perez Bergliaffa
We construct an analytical relativistic two fluid star characterized by a mixed core, where ordinary matter and dark matter coexist as two independently conserved incompressible pe…
Regular fluid of strings black hole with non trivial core and asymptotic structure by gravitational decoupling
Milko Estrada, Luis C. N. Santos, Leonardo G. Barbosa
Cloud-of-strings (CS) geometries provide an effective description of one-dimensional string distributions. However, their central singularity cannot be removed through the standard…
Geometric Saturation of the Scale Function in Black-Bounce Spacetimes: Spherical, Planar, and Hyperbolic Transverse Sections
Milko Estrada
We present a new construction for black-bounce spacetimes based on a deformation of the scale function that acts as a geometric saturation rather than introducing a prescribed cons…
Localized five-dimensional rotating brane-world black hole Analytically Connected to an to an AdS boundary
Milko Estrada, Francisco Tello-Ortiz
We provide a method to describe the geometry of an analytic, exponentially localized rotating braneworld black hole, using the Janis Newman algorithm in Hopf coordinates.…
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…
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…
A way of decoupling the gravitational bulk field equations of regular braneworld black holes to suppress the bulk singularities
Milko Estrada, T. M. Crispim, G. Alencar
We provide a methodology for decoupling the bulk gravitational field equations of braneworld black holes to suppress the bulk singularities. Thus, we provide a regular braneworld b…
Braneworld Black Bounce to Transversable Wormhole Analytically Connected to an asymptotically Boundary
T. M. Crispim, G. Alencar, Milko Estrada
We extend the recent approach from reference [1] to obtain complete and analytic solutions (both brane and bulk) of a Simpson-Visser (SV) geometry within a braneworld framework. Th…
Braneworld Black Bounce to Transversable Wormhole
Tiago M. Crispim, Milko Estrada, C. R. Muniz +1
We provide a way for embedding a 4-dimensional geometry corresponding to the Simpson Visser (SV) spacetime which is capable of representing a traversable wormhole, a one-way wormho…
Quantized -form Gauge Field in D-dimensional de Sitter Spacetime
E. W. D. Dantas, G. Alencar, I. Guedes +1
In this work, we utilize the dynamic invariant method to obtain a solution for the time-dependent Schrödinger equation, aiming to explore the quantum theory of a -form gauge fie…
Dymnikova-Schwinger traversable wormholes
Milko Estrada, Celio R. Muniz
In this paper, we obtain new -dimensional and asymptotically flat wormhole solutions by assuming a specific form of the energy density distribution. This is addressed by conside…
