Interacting Dark Sectors in Anisotropic Universe: Observational Constraints and Tension

Hassan Amirhashchi, Anil Kumar Yadav, Nafis Ahmad +1

The present study reveals observational constraints on the coupling between dark components of anisotropic Bianchi type I universe. We assume interaction between dark matter and da…

Recovering CDM Model From a Cosmographic Study

Hassan Amirhashchi, Soroush Amirhashchi

Using the mathematical definitions of deceleration and jerk parameters we obtain a general differential equation for squared Hubble parameter. For a constant jerk, this differentia…

Current Constraints on Anisotropic and Isotropic Dark Energy Models

Hassan Amirhashchi, Soroush Amirhashchi

We use Gaussian processes in combination with MCMC method to place constraints on cosmological parameters of three dark energy models including flat and curved FRW and Bianchi type…

Probing Dark Energy in The scope of Bianchi type I Spacetime

Hassan Amirhashchi

It is well known that flat FRW metric is a special case of Bianchi type I spacetime. In this paper, we use 38 Hubble parameter, , measurements at intermediate redshifts $0.07…

Viscous Dark Energy In Bianchi Type V Space-Time

Hassan Amirhashchi

We study the behavior of dark energy (DE) in the scope of anisotropic Bianchi type V (BV) space-time. First we derive Friedmann-Like Equations, then we compare the dark energy equa…
