The discovery of high-redshift supernovae and their cosmological implications

Type Ia supernova peak absolute magnitudes and light-curve widths have been observed to be tightly correlated, making this class of supernova a potential distance indicator and powerful cosmological probe. To this end, the Supernova Cosmology Project has been engaged in a systematic search for supernovae in the redshift range $0.3<z<0,7$ and has, to date, discovered nineteen supernovae. I will discuss several photometric systematic corrections that must be applied before distant supernovae Ia can be compared with local calibrators, the confidence to which we can determine light curve parameters with our photometry, and other possible systematic effects.
