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.…
Can Holographic dark energy models fit the observational data?
Mohammad Malekjani, Mehdi Rezaei, Iman A. Akhlaghi
In this work we investigate the holographic dark energy models with slowly time-varying model parameter defined based on the current Hubble horizon length scale. While the previous…
Spherical collapse model in agegraphic dark energy cosmologies
M. Rezaei, M. Malekjani
Under the commonly used spherical collapse model, we study how dark energy affects the growth of large scale structures of the Universe in the context of agegraphic dark energy mod…
