| dc.description | A power law cosmology is defined by the cosmological scale factor evolving as $t^α$. In this work, we put bounds on $α$ by using the joint test of the SNe Ia data from Supernova Legacy Survey (SNLS) and H(z) data with curvature constant $ k = 0, \pm 1$. We observe that the combined analysis with SNLS and H(z) data favours the open power cosmology with $α= 1.31^{+0.06}_{-0.05}. It is also interesting to note that an Einstein - de Sitter model $(α= 2/3)$ is ruled out at $2σ$ level. | |
