cds-question@unistra.frsupernovaeredshiftedphotometryvisible-astronomysurveysastronomical-modelsWe 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 {Lambda}CDM model, we find {Omega}_M_=0.334+/-0.018 from SNe Ia alone. For a flat w_0_CDM model, we measure w_0_=-0.90+/-0.14 from SNeIa alone, H_0_=73.5+/-1.1km/s/Mpc when including the Cepheid host distances and covariance (SH0ES), and w_0_=-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 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+ SNe Ia alone, H_0_=73.3+/-1.1km/s/Mpc when including SH0ES Cepheid distances, and w_a_=-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 H_0_ and cannot explain the present "Hubble tension" between local measurements and early universe predictions from the cosmological model.2022ApJ...938..110Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/938/110CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/607/665 : Type Ia supernovae at z>1 discovered by HST (Riess+, 2004)J/AJ/131/527 : UBVRI light curves of 44 type Ia supernovae (Jha+, 2006)J/ApJ/700/331 : Light curves of type Ia supernovae (CfA3) (Hicken+, 2009)J/ApJS/190/418 : Light curves for 165 SNe (Ganeshalingam+, 2010)J/A+A/523/A7 : Light curves of type Ia supernovae in SNLS (Guy+, 2010)J/ApJ/722/566 : Host galaxies of SNeIa in SDSS-II SN survey (Lampeitl+, 2010)J/MNRAS/406/782 : Type Ia supernovae luminosities (Sullivan+, 2010)J/PASP/122/1 : BVRI light curves of SN 2007gi (Zhang+, 2010)J/A+A/529/L4 : Reddening law of type Ia supernovae (Chotard+, 2011)J/ApJS/192/1 : Light-curve parameters from the SNLS (Conley+, 2011)J/ApJ/738/162 : SN Ia candidates from the SDSS-II SN Survey (Sako+, 2011)J/ApJS/200/12 : CfA4: light curves for 94 type Ia SNe (Hicken+, 2012)J/ApJ/746/85 : THe HST Cluster Supernova Survey.
