Interacting dark matter and modified holographic Ricci dark energy induce a relaxed Chaplygin gas

We investigate a model of interacting dark matter and dark energy given by a modified holographic Ricci's cutoff in a spatially flat Friedmann-Robertson-Walker (FRW) space-time. We consider a non line...
Baryon-density perturbations of large amplitude may exist if they are compensated by dark-matter perturbations so that the total density remains unchanged. Big-bang nucleosynthesis and galaxy clusters...
The dark matter assembly of the Local Group in constrained cosmological simulations of a LambdaCDM universe
galaxies: haloes cosmology: theory methods: N-body simulations

We make detailed theoretical predictions for the assembly properties of the Local Group (LG) in the standard LambdaCDM cosmological model. We use three cosmological N-body dark matter simulations from...

This letter discusses a modified Friedmann-Robertson-Walker cosmology in which the equation of state behaves like p = 3hamrn r; (h;m;n) 2 R. Many interesting features are revealed in particu...
We discuss G¨odel’s universe in the context of the induced-matter theory. We show that the problem of generating G¨odel’s metric from an extra dimension is equivalent to finding an embedding of G¨odel...
