摘要：
In the past three years two separate programs were initiated to study the rest-frame UV properties of Type Ia Supernovae (SNe). The low-redshift study was carried out using several ground-based facilities coupled with HST/STIS observations. The high-redshift program is an offshoot of the CFHT Legacy Survey and uses Keck/LRIS to obtain spectra. Here we present the preliminary results from each program and their implications for current cosmology measurements.
