A parametrization for the growth index of linear matter perturbations

Puxun Wu, Hongwei Yu, Xiangyun Fu

We propose a parametrization for the growth index of the linear matter perturbations, $γ (z) = γ_{0} + \frac{z}{1 + z} γ_{1}$ . The growth factor of the perturbations parameterized as $Ω_{m}^{γ}$ i…

The growth of linear perturbations in the DGP model

Xiangyun Fu, Puxun Wu, Hongwei Yu

We study the linear growth of matter perturbations in the DGP model with the growth index $γ$ as a function of redshift. At the linear approximation: $γ (z) \approx γ_{0} + γ_{0}^{'} z$ …

Density pertubation of unparticle dark matter in the flat Universe

Songbai Chen, Xiangyun Fu, Jiliang Jing

The unparticle has been suggested as a candidate of dark matter. We investigated the growth rate of the density perturbation for the unparticle dark matter in the flat Universe. Fi…
