Description
The primary interest in supernovae (SNe) over the last decade has been focussed on Type-Ia
(SNIa) for their use as `standardizable' candles in constraining cosmological models. Ongoing
observations of large samples of SNIa are being used to improve the measurement of
luminosity distance as a function of redshift, and thereby constrain cosmological parameters
further. Moreover, the gravitational lensing of SNIa by foreground cosmic structure along
their lines-of-sight has been used to constrain the properties of the lensing matter. There
remain, however, substantial difficulties in connecting observations with theory in the analysis
of SNe data. Moreover, in the forthcoming era of large SNe surveys, one will be faced with
the new problem of having to perform automated photometric classification of SNe. My
research in this thesis addresses these problems in the analysis of SNe observations.
