Can dark energy be expressed as a power series of the Hubble parameter?

Mehdi Rezaei, Mohammad Malekjani, Joan Sola

In this work we examine the possibility that the dark energy (DE) density, can be dynamical and appear as a power series expansion of the Hubble rate (and its derivatives)…

Structure formation in dark energy cosmologies described by PADE parameterization

Mehdi Rezaei

We study the imprints on the formation of cosmic structures of a particular class of dark energy parameterizations dubbed PADE parameterization. Here we investigate how dark energy…

Observational constraints on the oscillating dark energy cosmologies

Mehdi Rezaei

In this study we combine the background and the growth rate data in order to study the ability of the two oscillating dark energy parameterizations, to fit the observational data.…
