Abstract

We present Ω _m,Ω _Λ results based on a recently developed technique for analyzing the lightcurves of Type Ia supernovae. This technique (CMAGIC, for Color-Magnitude Intercept Calibration (Wang et al. 2003)) is based on the empirical uniformity of SNe Ia color-magnitude diagrams after maximum light, and has advantages over maximum-magnitude fits. In particular, CMAGIC is less affected by host-galaxy dust extinction. This result, based on 12 high redshift SNe Ia, provides a powerful check on previous cosmological results using Type Ia supernovae that have shown that the expansion of the universe is accelerating.
