Agegraphic dark energy: growth index and cosmological implications
M. Malekjani, S. Basilakos, A. Mehrabi +2
We study the main cosmological properties of the agegraphic dark energy model at the expansion and perturbation levels. Initially, using the latest cosmological data we implement a…
Spherical collapse model and cluster number counts in power law gravity
Mohammad Malekjani, Spyros Basilakos, Neda Heidari
We study the spherical collapse model (SCM) in the framework of spatially flat power law gravity model. We find that the linear and non-linear growth of sph…
Constraints on shear and rotation with massive galaxy clusters
Ahmad Mehrabi, Francesco Pace, Mohammad Malekjani +1
A precise determination of the mass function is an important tool to verify cosmological predictions of the CDM model and to infer more precisely the better model describing the…
Growth of spherical overdensities in scalar-tensor cosmologies
N. Nazari-Pooya, M. Malekjani, F. Pace +1
The accelerated expansion of the universe is a rather established fact in cosmology and many different models have been proposed as a viable explanation. Many of these models are b…
