Singularities and Soft-Big Bang in a viscous CDM model
Norman Cruz, Esteban González, José Jovel
In this paper we explore the different types of singularities that arise in the CDM model when dissipative processes are considered, in the framework of the Eckart's theory. In…
Testing a nonlinear solution of the Israel-Stewart theory
Miguel Cruz, Norman Cruz, Esteban González +1
In this work, we test the capability of an exact solution found in the framework of a nonlinear extension of the Israel-Stewart theory to fit the supernovae Ia, gravitational lensi…
Time-averaging axion-like interacting scalar fields models
Saikat Chakraborty, Esteban González, Genly Leon +1
In this paper, we study a cosmological model inspired in the axionic matter with two canonical scalar fields and interacting through a term added to its potential. Intr…
Variational symmetries and superintegrability in multifield cosmology
Alex Giacomini, Esteban González, Genly Leon +1
We consider a spatially flat Friedmann--Lema\^ıtre--Robertson--Walker background space with an ideal gas and a multifield Lagrangian consisting of two minimally coupled scalar fiel…
Averaging generalized scalar field cosmologies III: Kantowski--Sachs and closed Friedmann--Lemaître--Robertson--Walker models
Genly Leon, Esteban González, Samuel Lepe +2
Scalar field cosmologies with a generalized harmonic potential and matter with energy density , pressure , and barotropic equation of state (EoS) $p_m=(γ-1)ρ_m, \; γ\in[0…
Averaging Generalized Scalar Field Cosmologies II: Locally Rotationally Symmetric Bianchi I and flat Friedmann-Lemaître-Robertson-Walker models
Genly Leon, Sebastián Cuéllar, Esteban González +3
Scalar field cosmologies with a generalized harmonic potential and a matter fluid with a barotropic Equation of State (EoS) with barotropic index for the Locally Rotationally S…
