We measure cosmological parameters using the three-dimensional power spectrum P (k)
from over 200 000 galaxies in the Sloan Digital Sky Survey (SDSS) in combination with …

Nature's simplest field, the scalar field, has been the protagonist of physical theories for a
long time. Even before the publication of the theory of general relativity G. Nordström …

Quintessence issues can be achieved by taking into account higher order curvature
invariants into the effective action of gravitational field. Such an approach is naturally related …

We investigate the consequences of an imperfect dark energy fluid on the large scale
structure. A phenomenological three parameter fluid description is used to study the effect of …

We review the implications of having a nontrivial matter component in the Universe and the
potential for detecting such a component through the matter power spectrum and integrated …

We study the implications on both background and perturbation evolution of introducing a
Chaplygin gas component in the universe's ingredients. We perform likelihood analyses …

We consider the effect of inhomogeneities on the expansion of the Einstein–de Sitter
universe. We find that the back-reaction of linear scalar metric perturbations results in …

In this paper we consider the holographic model of interacting dark energy in non-flat
universe. With the choice of c≤ 0.84, the interacting holographic dark energy can be …

We investigate a model of the interacting holographic dark energy with cold dark matter
(CDM). If the holographic energy density decays into CDM, we find two types of the effective …
