2.2 Dark energy parameterization As mentioned earlier, constraining the dark energy using its equation of state is known to be parameterization dependent, e.g. (Wang & Tegmark (2004); Upadhye et al. (2004)), and also suffers from a smearing due to the double integration involved (Maor et al. (2002); Maor et al. (2001)). Alternatively, one can probe directly the variations of the dark energy density as a function of redshift ρde(z). On the other hand, it has been argued that the equation of ...
