On the nature of dark matter
T. Matos, L. A. Urena-Lopez
Dark matter in the universe seems to be one of the most important puzzles science has to face in this moment. In this essay we point out that dark matter could be a spin-0 fundamen…
Scalar Field Dark Matter, Cross Section and Planck-Scale Physics
T. Matos, L. A. Urena-Lopez
In recent papers we have proposed that the dark matter of the Universe could be from scalar field origin. In this letter, we find that if the scale of renormalization of the model…
A Further Analysis of a Cosmological Model of Quintessence and Scalar Dark Matter
T. Matos, L. A. Urena-Lopez
We present the complete solution to a 95% scalar field cosmological model in which the dark matter is modeled by a scalar field with the scalar potential $V(Φ)=V_{o}[ \cosh {(λ…
Quintessence and Scalar Dark Matter in the Universe
T. Matos, L. A. Urena-Lopez
Continuing with previous works, we present a cosmological model in which dark matter and dark energy are modeled by scalar fields and , respectively, endowed with the scalar…
A new cosmological tracker solution for Quintessence
L. A. Urena-Lopez, T. Matos
In this paper we propose a quintessence model with the potential , which asymptotic behavior corresponds to an inverse power-law potentia…
Scalar Field as Dark Matter in the Universe
T. Matos, F. S. Guzman, L. A. Urena-Lopez
We investigate the hypothesis that the scalar field is the dark matter and the dark energy in the Cosmos, wich comprises about 95% of the matter of the Universe. We show that this…
