摘要：

We investigate the possibility that dark energy is scaling with epochs. A phenomenological model is introduced whose energy density depends on the redshift z in such a way that a smooth transition among the three dominant phases of the Universe evolution (radiation era, matter domination, asymptotic de Sitter state) is achieved. We use the Wilkinson Microwave Anisotropy Probe cosmic microwave background data and the luminosity distances of Type Ia Supernovae to test whether the model is in agreement with astrophysical observations.
