Effects of ghost dark energy perturbations on the evolution of spherical overdensities
Mohammad Malekjani, Tayebe Naderi, Francesco Pace
While in the standard cosmological model the accelerated expansion of the Universe is explained by invoking the presence of the cosmological constant term, it is still unclear the…
Evolution of spherical overdensities in holographic dark energy models
Tayebe Naderi, Mohammad Malekjani, Francesco Pace
In this work we investigate the spherical collapse model in flat FRW dark energy universes. We consider the Holographic Dark Energy (HDE) model as a dynamical dark energy scenario…
Spherical collapse and the holographic dark energy model
Tayebe Naderi, Mohammad Malekjani
In this work we investigate the spherical collapse model in flat FRW universe containing dark energy component. We consider the Holographic Dark Energy (HDE) model as a dynamical d…
