ΛΛ-CDM type Heckmann - Suchuking model and union 2.1 compilation

preprint2016arXivOpen access

Abstract

In this paper, we have investigated ΛΛCDM type cosmological model in Heckmann-Schucking space-time, by using 287 high red shift (.3≤z≤1.4 .3 \leq z \leq 1.4 ) SN Ia data of observed absolute magnitude along with their possible error from Union 2.1 compilation. We have used χ2χ^{2} test to compare Union 2.1 compilation observed data and corresponding theoretical values of apparent magnitude (m)(m). It is found that the best fit value for (Ωm)0(Ω_{m})_0, (ΩΛ)0(Ω_Λ)_0 and (Ωσ)0(Ω_σ)_0 are 0.29400.2940, 0.70580.7058 and 0.00020.0002 respectively and the derived model represents the features of accelerating universe which is consistent with recent astrophysical observations.
