DES supernova data alone give Omega_M = 0.352 +/- 0.017 in flat LambdaCDM and confirm acceleration at >5 sigma, with dark energy consistent with a cosmological constant to within ~2 sigma when combined with other probes.

The local Hubble constant is measured as 73.04 ± 1.04 km/s/Mpc from Cepheid-calibrated Type Ia supernovae, showing a 5-sigma discrepancy with the Planck+LCDM prediction.
A new two-parameter empirical magnitude-redshift relation for Type Ia supernovae fits observations comparably or better than LambdaCDM and indicates uniform cosmic acceleration.
