Dark energy with polytropic equation of state
Equation of state parameter plays a significant role for guessing the real nature of dark energy. In the present paper polytropic equation of state p = ωρn is chosen for some of the kinematical Λ-models viz., Λ ∼ (ȧ/a), Λ ∼ ä/a and Λ ∼ ρ. Although in dust cases (ω = 0) closed form solutions show no dependency on the polytropic index n, but in non-dust situations some new possibilities are opene...
متن کاملThe dark energy equation of state
We perform a study of cosmic evolution with an equation of state parameter ω(t) = ω0 + ω1(tḢ/H) by selecting a phenomenological Λ model of the form, Λ̇ ∼ H. This simple proposition explains both linearly expanding and inflationary Universes with a single set of equations. We notice that the inflation leads to a scaling in the equation of state parameter, ω(t), and hence in equation of state. In ...
متن کاملMapping the Dark Energy Equation of State
The acceleration of the expansion of the universe has deep implications for structure formation, the composition of the universe, and its fate. Roughly 70% of the energy density is in a dark energy, whose nature remains unknown. Mapping the expansion history through supernovae, mapping the geometry of the universe and formation of structure through redshift surveys, and mapping the distance to ...
متن کاملInteracting dark energy with inhomogeneous equation of state
We have investigated the model of dark energy interacting with dark matter by choosing inhomogeneous equations of state for the dark energy and a non-linear interaction term for the underlying interaction. The equations of state have dependencies either on the energy densities, the redshift, the Hubble parameter or the bulk viscosity. We have considered these possibilities and have derived the ...
متن کاملConstraining the Dark Energy Equation of State with Cosmic Voids
Our universe is observed to be accelerating due to the dominant dark energy with negative pressure. The dark energy equation of state (w) holds a key to understanding the ultimate fate of the universe. The cosmic voids behave like bubbles in the universe so that their shapes must be quite sensitive to the background cosmology. Assuming a flat universe and using the priors on the matter density ...
