ABSTRACT

We investigate a second order parabolic parametrization, w(a) = wt + wa(at − a)2, which is a direct characterization of a possible turning in w. The cosmological consequence of this parametrization is explored by using the observational data of the SNLS3 type Ia supernovae sample, the CMB measurements from WMAP9 and Planck, the Hubble parameter measurement from HST, and the baryon acoustic oscillation (BAO) measurements from 6dFGS, BOSS DR11 and improved WiggleZ. We found the existence of a turning point in w at a ∼ 0.7 is favored at 1σ CL. In the epoch 0.55 < a < 0.9, w < −1 is favored at 1σ CL, and this significance increases near a = 0.8, reaching a 2σ CL. The parabolic parametrization achieve equivalent performance to the ΛCDM and Chevallier-Polarski-Linder (CPL) models when the Akaike information criterion was used to assess them. Our analysis shows the value of considering high order parametrizations when studying the cosmological constraints on w. More... »

The cosmological consequence of this parametrization is explored by using the observational data of the SNLS3 type Ia supernovae sample, the CMB measurements from WMAP9 and Planck, the Hubble parameter measurement from HST, and the baryon acoustic oscillation (BAO) measurements from 6dFGS, BOSS DR11 and improved WiggleZ. We found the existence of a turning point in w at a \u223c 0.7 is favored at 1\u03c3 CL. In the epoch 0.55 < a < 0.9, w < \u22121 is favored at 1\u03c3 CL, and this significance increases near a = 0.8, reaching a 2\u03c3 CL. The parabolic parametrization achieve equivalent performance to the \u039bCDM and Chevallier-Polarski-Linder (CPL) models when the Akaike information criterion was used to assess them. Our analysis shows the value of considering high order parametrizations when studying the cosmological constraints on w.",
