Journal ArticleDOI
Interacting models may be key to solve the cosmic coincidence problem
TL;DR: In this article, it is argued that cosmological models that feature a flow of energy from dark energy to dark matter may solve the coincidence problem of late acceleration (i.e., why the energy densities of both components are of the same order precisely today).

Journal ArticleDOI
Tachyon warm inflationary universe models
TL;DR: In this paper, a tensor perturbation model for a constant dissipation parameter Γ in a tachyon field theory was proposed and general conditions required for these models to be realizable are derived and discussed.
Journal ArticleDOI
Emergent universe in a Jordan-Brans-Dicke theory
TL;DR: In this article, the emergent universe model in the context of a self-interacting Jordan-Brans-Dicke theory is studied, where the model presents a stable past eternal static solution which eventually enters a phase where the stability of this solution is broken leading to an inflationary period.
Journal ArticleDOI
(2+1)-dimensional black hole with Coulomb-like field
TL;DR: In this article, a (2+1)-static black hole solution with a nonlinear electric field was derived, and the obtained solution is singular at the origin of coordinates, and an interesting asymptotically flat solution for Λ = 0.
