Dark Energy in a Hyperbolic Universe

Dark energy models due to a slowly evolving scalar (quintessence) field φ are studied for various potentials V (φ) in a universe with negative curvature. The potentials differ in whether they possess a minimum at φ = 0 or are monotonically declining, i. e. have a minimum at infinity. The angular power spectrum Cl of the cosmic microwave background (CMB) as well as the magnitude-redshift relatio...

Interacting holographic dark energy model in non - flat universe

We employ the holographic model of interacting dark energy to obtain the equation of state for the holographic energy density in non-flat (closed) universe enclosed by the event horizon measured from the sphere of horizon named L.

The Dark Universe

For a few years now, cosmology has a standard model. By this term, we mean a consistent theoretical background which is at the same time simple and broad enough to offer coherent explanations for the vast majority of cosmological phenomena. This review will briefly summarise the cosmological model, then proceed to discuss what we know from observations about the evolution of the Universe and it...

The Dark Universe Riddle

In this work we review some of the theoretical efforts and experimental evidences related to Dark matter and Dark energy problems in the universe. These dilemmas show us how incomplete our knowledge of gravity is, and how our concepts about the universe must at least be revised. Mainly on the Wilkinson Microwave Anisotropy Probe (WMAP) fifth year data indicates that more than 90% of the total e...

A Dark-Disk Universe

We point out that current constraints on dark matter imply only that the majority of dark matter is cold and collisionless. A subdominant fraction of dark matter could have much stronger interactions. In particular, it could interact in a manner that dissipates energy, thereby cooling into a rotationally-supported disk, much as baryons do. We call this proposed new dark matter component Double-...
