Abstract:
Using the largest single-survey sample of Type Ia supernovae (SNe Ia)
to date, we study the relationship between properties of SNe Ia and
those of their host galaxies, focusing primarily on correlations with
Hubble residuals (HRs). Our sample consists of 345 photometrically
classified or spectroscopically confirmed SNe Ia discovered as part of
the SDSS-II Supernova Survey (SDSS-SNS). This analysis utilizes
host-galaxy spectroscopy obtained during the SDSS-I/II spectroscopic
survey and from an ancillary program on the SDSS-III Baryon
Oscillation Spectroscopic Survey that obtained spectra for nearly all
host galaxies of SDSS-II SN candidates. In addition, we use
photometric host-galaxy properties from the SDSS-SNS data release such
as host stellar mass and star formation rate. We confirm the
well-known relation between HR and host-galaxy mass and find a
3.6σ significance of a nonzero linear slope. We also recover
correlations between HR and host-galaxy gas-phase metallicity and
specific star formation rate as they are reported in the literature.
With our large data set, we examine correlations between HR and
multiple host-galaxy properties simultaneously and find no evidence of
a significant correlation. We also independently analyze our
spectroscopically confirmed and photometrically classified SNe Ia and
comment on the significance of similar combined data sets for future
surveys.
Description:
Observations from the full 3yr SDSS-II Supernova Survey (SDSS-SNS;
Sako et al. 2014, 1401.3317) were used for our SN Ia sample, and
a combination of spectra from SDSS and BOSS was utilized for
host-galaxy spectroscopy.
