Spectral Analysis of Type Ia Supernovae
Gaston Folatelli
I will present the results of some studies based on quantitative analysis of type Ia supernova
spectroscopy. The goals of these studies are: (a) shed some
light on the physical properties of SNe; (b) study their homogeneity and
possibly refine the standard candle calibration; and (c) address the issue of evolution with redshift.
These studies are based on a fairly large set of spectra from nearby SNe
plus a very interesting collection of high-redshift objects. The upcoming large data sets from new SN experiments will benefit from this work as systematics controls will have to keep up with the reduction of statistical uncertainties.
