Scalar dark matter in spiral galaxies
F. S. Guzman, T. Matos, H. Villegas-Brena
An exact, axially symmetric solution to the Einstein-Klein-Gordon field equations is employed to model the dark matter in spiral galaxies. The extended rotation curves from a previ…
The Interior Field of a Magnetized Einstein-Maxwell Object
Tonatiuh Matos
Using the Harmonic map ansatz, we reduce the axisymmetric, static Einstein-Maxwell equations coupled with a magnetized perfect fluid to a set of Poisson-like equations. We were abl…
Scalar Fields as Dark Matter in Spiral Galaxies
F. Siddhartha Guzman, Tonatiuh Matos
We present a model for the dark matter in spiral galaxies, which is a result of a static and axial symmetric exact solution of the Einstein-Dilaton theory. We suposse that dark mat…
Exact inflationary solutions
Gabriella Piccinelli, Tonatiuh Matos, Merced Montesinos
We present a new class of exact inflationary solutions for the evolution of a universe with spatial curvature, filled with a perfect fluid, a scalar field with potential $V_{\pm}(ϕ…
