Kavli Affiliate: Naoshi Sugiyama | Summary:We determine constraints on spatially-flat tilted dynamical dark energy XCDM and $φ$CDM inflation models by analyzing Planck 2015 cosmic microwave background (CMB) anisotropy data and baryon acoustic oscillation (BAO) distance measurements. XCDM is a simple and widely used but physically inconsistent parameterization of dynamical dark energy, while the $φ$CDM model […]
