Abstract

We present a generalized correlation analysis of type Ia supernova spectra with a focus on spectral features that correlate with absolute magnitude in ways that are not already accounted for by color and lightcurve stretch. The results reveal new spectral correlations beyond those of the classic metrics of feature ratios (RSi, RSiS, RCa, EDCa). These new correlations could be used to improve the calibration of type Ia supernovae for cosmology measurements beyond what is possible with stretch and color alone.
