The Pantheon+ Analysis: Cosmological Constraints

Abstract

We present constraints on cosmological parameters from the Pantheon+ analysis of 1701 light curves of 1550 distinct Type Ia supernovae (SNe Ia) ranging in redshift from $z=0.001$ to 2.26. This work features an increased sample size, increased redshift span, and improved treatment of systematic uncertainties in comparison to the original Pantheon analysis and results in a factor of two improvement in cosmological constraining power. For a Flat$\Lambda$CDM model, we find ${\Omega }_M=0.334\pm 0.018$ from SNe Ia alone. For a Flat$w_0$CDM model, we measure $w_0=-0.90\pm 0.14$ from SNe Ia alone, H${}_0=73.5\pm 1.1$ km s${}^{-1}$ Mpc${}^{-1}$ when including the Cepheid host distances and covariance (SH0ES), and $w_0=-0.978_{-0.031}^{+0.024}$ when combining the SN likelihood with constraints from the cosmic microwave background (CMB) and baryon acoustic oscillations (BAO); both $w_0$ values are consistent with a cosmological constant. We also present the most precise measurements to date on the evolution of dark energy in a Flat$w_0{w}_a$CDM universe, and measure $w_a=-0.1_{-2.0}^{+0.9}$ from Pantheon+ alone, H${}_0=73.3\pm 1.1$ km s${}^{-1}$ Mpc${}^{-1}$ when including SH0ES, and $w_a=-0.65_{-0.32}^{+0.28}$ when combining Pantheon+ with CMB and BAO data. Finally, we find that systematic uncertainties in the use of SNe Ia along the distance ladder comprise less than one third of the total uncertainty in the measurement of H${}_0$ and cannot explain the present "Hubble tension" between local measurements and early-Universe predictions from the cosmological model.
