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.

Two-parameter Weibull or exponentiated exponential distributions describe simulated type Ia supernova extinction in 3D galaxies much better than the standard exponential PDF, and their use shifts fitted intrinsic SN colors redder by about 2σ.

Examining extinction distributions for type Ia supernovae in simulated 3D galaxies
Two-parameter Weibull or exponentiated exponential distributions describe simulated type Ia supernova extinction in 3D galaxies much better than the standard exponential PDF, and their use shifts fitted intrinsic SN colors redder by about 2σ.
