The Complete Light-curve Sample of Spectroscopically Confirmed SNe Ia from Pan-STARRS1 and Cosmological Constraints from the Combined Pantheon Sample

Short summary

The Pantheon Sample, combining 1000+ SNe Ia from PS1 and other surveys, provides the most precise dark energy measurements to date, yielding w = -1.00+0.05-0.06 for the wCDM model and w = -1.03+0.04-0.04 for the CDM model when combined with CMB, BAO, and H0 data.
