We reconstruct the dark energy density ρX(z) as a free function from current type Ia supernova (SN Ia) data (Tonry et al. 2003; Barris et al. 2003; Knop et al. 2003), together with the Cosmic Microwave Background (CMB) shift parameter from CMB data (WMAP, CBI, and ACBAR), and the large scale structure (LSS) growth factor from 2dF galaxy survey data. We parametrize ρX(z) as a continuous function, given by interpolating its amplitudes at equally spaced z values in the redshift range covered by SN… CONTINUE READING
