Forecasting cosmological constraints from age of high-z galaxies
2014
We perform Monte Carlo simulations based on current age estimates of high-z objects to forecast constraints on the equation of state (EoS) of the dark energy. In our analysis, we use two different EoS parameterizations, namely, the so-called Chevallier-Polarski-Linder (CPL) and its uncorrelated form, and calculate the improvements on the figure of merit (FoM) for both cases. Although there is a clear dependence of the FoM with the size and accuracy of the synthetic age samples, we find that the most substantial gain in FoM comes from a joint analysis involving age and baryon acoustic oscillation data.
