Constraints on The Dark Energy Equation of State And The Deceleration Parameter From Recent Cosmic Observations
Hassan Amirhashchi
We study the constraints on dark energy equation of state and the deceleration parameter from the recent observational data including Hubble data and the cosmic microwa…
An Interacting Scenario for Dark Energy in Bianchi Type-I Universe
Hassan Amirhashchi, S. N. A. Qazi, Hishamuddin Zainuddin
We study the interaction between dark energy (DE) and dark matter (DM) in the scope of anisotropic bianchi type I space-time. First we derive the general form of the dark energy eq…
Viscous Dark Energy and Phantom Field in An Anisotropic Universe
Hassan Amirhashchi, Anirudh Pradhan
In this paper we have investigated the general form of viscous and non-viscous dark energy equation of state (EoS) parameter in the scope of anisotropic Bianchi type I space-time.…
Two-Fluid Scenario for Dark Energy Models in an FRW Universe-Revisited
Bijan Saha, Hassan Amirhashchi, Anirudh Pradhan
In this paper we study the evolution of the dark energy parameter within the scope of a spatially homogeneous and isotropic Friedmann-Robertson-Walker (FRW) model filled with barot…
L.R.S. Bianchi type II Stiff Fluid cosmological model with Decaying Vacuum Energy Density in general relativity
Hassan Amirhashchi
Locally rotationally symmetric (L.R.S.) Bianchi type II stiff fluid cosmological model is investigated. To get the deterministic model of the universe, we have assumed a condition…
An Interacting Two-Fluid Scenario for Dark Energy in FRW Universe
Hassan Amirhashchi, Anirudh Pradhan, Bijan Saha
We study the evolution of the dark energy parameter within the scope of a spatially flat and isotropic Friedmann-Robertson-Walker (FRW) model filled with barotropic fluid and dark…
