Abstract:
We present constraints on cosmological parameters from the Pantheon+
analysis of 1701 light curves of 1550 distinct Type Ia supernovae
(SNeIa) ranging in redshift from z=0.001 to 2.26. This work features
an increased sample size from the addition of multiple
cross-calibrated photometric systems of SNe covering an increased
redshift span, and improved treatments of systematic uncertainties in
comparison to the original Pantheon analysis, which together result in
a factor of 2 improvement in cosmological constraining power. For a
flat ΛCDM model, we find ΩM=0.334±0.018 from SNe Ia
alone. For a flat w0CDM model, we measure w0=-0.90±0.14 from
SNeIa alone, H0=73.5±1.1km/s/Mpc when including the Cepheid host
distances and covariance (SH0ES), and w0=-0.978-0.031+0.024 when
combining the SN likelihood with Planck constraints from the cosmic
microwave background (CMB) and baryon acoustic oscillations (BAO);
both w0 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 w0waCDM universe, and measure wa=-0.1-2.0+0.9
from Pantheon+ SNe Ia alone, H0=73.3±1.1km/s/Mpc when including
SH0ES Cepheid distances, and wa=-0.65-0.32+0.28 when combining
Pantheon+ SNe Ia 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 H0 and cannot explain the present "Hubble tension"
between local measurements and early universe predictions from the
cosmological model.
Description:
This paper is the culmination of a series of papers that comprise the
Pantheon+ analysis.
The light-curve data is described in detail by
Scolnic+ 2022ApJ...938..113S 2022ApJ...938..113S and references therein. The full set of
spectroscopically classified photometric light curves is compiled from
18 different publicly available and privately released samples. In
total, 2077 supernova (SN) light-curve fits converged using SALT2;
after quality cuts are applied, this results in 1701 SN light curves
of 1550 unique SNe Ia usable for cosmological constraints.
The redshifts and peculiar velocities of the SNe used here are given
by Carr+ (2022, J/other/PASA/39.46), and a comprehensive analysis of
peculiar velocities is presented by Peterson+ 2022ApJ...938..112P 2022ApJ...938..112P
