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…
Constraining Bianchi Type I Universe With Type Ia Supernova and H(z) Data
H. Amirhashchi, S. Amirhashchi
We use recent 36 observational Hubble data (OHD) in the redshift range , latest \textgravedbl joint light curves\textacutedbl (JLA) sample, comprised of 740 ty…
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…
Interacting Viscous Dark Energy in Bianchi Type-III Universe
Hassan Amirhashchi
In this paper we study the evolution of the equation of state of viscous dark energy in the scope of Bianchi type III space-time. We consider the case when the dark energy is minim…
