Type Ia supernovae (SNe Ia) are one of the pillars of modern observational cosmology, since they are good standard candles for distance measurements in the universe. The cosmological analysis using SNe Ia requires the observation of both high and low-redshift objects, and the smaller statistic of events on the latter case represents a major source of uncertainties.This thesis takes place within the SNfactory project, which aims to study nearby (0.03 An extraction pipeline of the differential photometric ratios between nights, needed for the flux calibration of the spectra, was built. The systematic errors affecting these ratios are estimated to be below 2%, and spectrophotometric light curves of standard stars show a 5% photometric precisio...
