Horndeski fermion-boson stars
Armando A. Roque, L. Arturo Ureña-López
We establish the existence of static and spherically symmetric fermion-boson stars, in a low energy effective model of (beyond) Horndeski theories. These stars are in equilibrium,…
Tracker phantom field and a cosmological constant: dynamics of a composite dark energy model
Francisco X. Linares Cedeño, Nandan Roy, L. Arturo Ureña-López
In this work, we study tracker phantom dark energy models with a general parameterization of the scalar potentials. Our analysis also considers the scenario of having both phantom…
Generalized tracker quintessence models for dark energy
L. Arturo Urena-Lopez, Nandan Roy
We study the dynamical properties of tracker quintessence models using a general parametrization of their corresponding potentials, and show that there is a general condition for t…
Ultralight DM bosons with an Axion-like potential: scale-dependent constraints revisited
Francisco X. Linares Cedeño, Alma X. González-Morales, L. Arturo Ureña-López
A scalar field endowed with a trigonometric potential has been proposed to play the role of Dark Matter. A deep study of the cosmological evolution of linear perturbations, and…
Gravitational atoms: general framework for the construction of multistate axially symmetric solutions of the Schrödinger-Poisson system
F. S. Guzmán, L. Arturo Ureña-López
We present a general strategy to solve the stationary Schrödinger-Poisson (SP) system of equations for multistates with axial symmetry. The approach allows us to obtain the well kn…
Scalar field dark matter as an alternative explanation for the anisotropic distribution of satellite galaxies
Jordi Solís-López, Francisco S. Guzmán, Tonatiuh Matos +2
In recent years, the scalar field dark matter (SFDM), also called ultralight bosonic dark matter, has received considerable attention due to the number of problems it might help to…
