Exploring Models of Running Vacuum Energy with Viscous Dark Matter from a Dynamical System Perspective
Norman Cruz, Gabriel Gomez, Esteban Gonzalez +2
Running vacuum models and viscous dark matter scenarios beyond perfect fluid idealization are two appealing theoretical strategies that have been separately studied as alternatives…
A new Parametrization for Bulk Viscosity Cosmology as Extension of the CDM Model
Gabriel Gómez, Guillermo Palma, Ángel Rincón +2
Bulk viscosity in cold dark matter is an appealing feature that introduces distinctive phenomenological effects in the cosmological setting as compared to the CDM model. Under t…
Testing dissipative dark matter in causal thermodynamics
Norman Cruz, Esteban González, Guillermo Palma
In this paper we study the consistency of a cosmological model representing a universe filled with a one-component dissipative dark matter fluid, in the framework of the causal Isr…
Exact analytical solution for an Israel-Stewart Cosmology
Norman Cruz, Esteban González, Guillermo Palma
In this article we report a novel analytic solution for a cosmological model with a matter content described by a one component dissipative fluid, in the framework of the causal Is…
Bouncing solutions from generalized EoS
F. Contreras, N. Cruz, G. Palma
We present an exact analytical bouncing solution for a closed universe filled with only one exotic fluid with negative pressure, obeying a Generalized Equations of State (GEoS) of…
Interacting warm dark matter
Norman Cruz, Guillermo Palma, David Zambrano +1
We explore a cosmological model composed by a dark matter fluid interacting with a dark energy fluid. The interaction term has the non-linear lambda*(rho_m)^alpha * (rho_e)^beta fo…
