Evidence for dark energy from SN-only constraints. Here we show confidence contours at 68% and 95% for the Ω_m and Ω_Λ cosmological parameters for the ﹩o\mathrm{CDM}﹩ model for both the Riess et al. (1998) discovery sample and the Pantheon sample. The Pantheon constraints with systematic uncertainties are shown in red, and those with only statistical uncertainties are shown in gray (line).
