Abstract

In this paper, we have investigated Λ\LambdaCDM type cosmological model in Heckmann-Schucking space-time, by using 287 high red shift (.3z1.4 .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 χ2\chi^{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(\Omega_{m})_0, (ΩΛ)0(\Omega_{\Lambda})_0 and (Ωσ)0(\Omega_{\sigma})_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.
