Effect of low anisotropy on cosmological models by using supernova data

Hossienkhani, H.; Yousefi, H.; Azimi, N.

By using the supernovae type Ia (SNIa) data we study influence of the anisotropy (although low) on the evolution of the universe and compare ΛCDM model with 6 representative parametrizations of the recent Hubble expansion history H(z). To compare these models we use the maximum likelihood method for find that the best fit dynamical w(z) and q(z) o…
