Determination of the metric of a Schwarzschild black hole surrounded by a halo of dark matter
M. Castillo Alarcón, Leonel Bixano, I. A. Sarmiento-Alvarado +2
Following the landmark acquisition of the first image of a black hole, systems comprising a black hole enveloped by a dark matter halo have attracted considerable attention. This w…
Exact lambdavacuum solutions in higher dimensions
I. A. Sarmiento-Alvarado, P. Wiederhold, T. Matos
In this work, we obtain exact solutions to the -dimensional Einstein Field Equations with a non-zero cosmological constant for . These solutions depend on a set $\{ A…
One-dimensional subspaces of the Chiral Equations
I. A. Sarmiento-Alvarado, Petra Wiederhold, Tonatiuh Matos
In this work we find solutions of the ()-dimensional Einstein Field Equations (EFE) with commuting Killing vectors in vacuum. In the presence of Killing vectors, the E…
Flat subspaces of the chiral equations
I. A. Sarmiento-Alvarado, P. Wiederhold, T. Matos
In this work, we introduce a method for finding exact solutions to the vacuum Einstein field equations in higher dimensions from a given solution to the chiral equation. When consi…
Axially symmetric wormholes
I. A. Sarmiento-Alvarado, Leonel Bixano, Tonatiuh Matos
In this work, we derive an exact vacuum solution to the Einstein field equations that depends on three constant parameters: the throat radius , a parameter , which is close…
A Brief Review of Wormhole Cosmic Censorship
Leonel Bixano, I. A. Sarmiento-Alvarado, Tonatiuh Matos
Spacetime singularities, in the sense that curvature invariants are infinite at some point or region, are thought to be impossible to observe, and must be hidden within an event ho…
