Abstract: The Nearby Supernova Factory (SNfactory1) will obtain and study a uniform high-quality dataset of flux-calibrated optical spectra at 10- 15 epochs, starting 5-15 days before maximum light, for each of approximately 300 nearby type Ia supernovae (SNe Ia). When combined with current (SCP, HZSST, SNLS, ESSENCE) and future (SNAP, LSST) datasets of high-redshift SNe Ia, the SNFactory dataset will substantially improve the statistical measurements of the dark energy equation of state. This project will also improve our understanding of SNe Ia and their use as standardized candles. We report on first light observations with the SNfactory follow-up instrument, the Supernova Integral Field Spectrograph.
