A causal viscous cosmology without singularities

Understand

An isotropic and homogeneous cosmological model with a source of dark energy is studied.

• That source is simulated with a viscous relativistic fluid with minimal causal correction.
• In this model the restrictions on the parameters coming from the following conditions are analized: a) energy density without singularities along time, b) scale factor increasing with time, c) universe accelerated at present time, d) state equation for dark energy with "w" bounded and close to -1.
• It is found that those conditions are satified for the following two cases.
