Abstract:
We present a public, open-source relational data base (we name
kaepora) containing a sample of 4975 spectra of 777 Type Ia supernovae
(SNe Ia). Since we draw from many sources, we significantly improve
the spectra by inspecting these data for quality, removing galactic
emission lines and cosmic rays, generating variance spectra, and
correcting for the reddening caused by both MW and host-galaxy dust.
With our data base, we organize this homogenized data set by 56 unique
categories of SN-specific and spectrum-specific metadata. With
kaepora, we produce composite spectra of subpopulations of SNe Ia and
examine how spectral features correlate with various SN properties.
These composite spectra reproduce known correlations with phase,
light-curve shape, and host-galaxy morphology. With our large data
set, we are also able to generate fine-grained composite spectra
simultaneously over both phase and light-curve shape. The colour
evolution of our composite spectra is consistent with other SN Ia
template spectra, and the spectral properties of our composite spectra
are in rough agreement with these template spectra with some subtle
differences. We investigate the spectral differences of SNe Ia that
occur in galaxies with varying morphologies. Controlling for
light-curve shape, which is highly correlated with host-galaxy
morphology, we find that SNe Ia residing in late-type and early-type
galaxies have similar spectral properties at multiple epochs. However
for SNe Ia in these different environments, their spectra appear to
have Ca ii near-infrared triplet features that have slightly different
strengths. Although this is apparent in the composite spectra and
there is some difference in the populations as seen by individual
spectra, this difference is not large enough to indicate differences
in the underlying populations. All individual spectra and metadata are
available in our open-source data base kaepora along with the tools
developed for this investigation to facilitate future investigations
of SN Ia properties.
Description:
Our data base currently contains 4975 spectra of 777 SNe Ia. The full
sample is comprised of spectra from heterogeneous data sources.
