Exploring uncertainties in dark energy constraints using current observational data with Planck 2015 distance priors

We explore the systematic uncertainties in dark energy constraints using the latest observational data from Type Ia Supernovae (SNe Ia), galaxy clustering, and cosmic microwave background anisotropy (CMB) data. We use the Joint Lightcurve Analysis (JLA) set of 740 SNe Ia, galaxy clustering measurements of H(z)s and DA(z)/s (where s is the sound horizon at… (More)
