Abstract:
We present photometric and spectroscopic observations of galaxies
hosting Type Ia supernovae (SNe Ia) observed by the Nearby Supernova
Factory. Combining Galaxy Evolution Explorer (GALEX) UV data with
optical and near-infrared photometry, we employ stellar population
synthesis techniques to measure SN Ia host galaxy stellar masses, star
formation rates (SFRs), and reddening due to dust. We reinforce the
key role of GALEX UV data in deriving accurate estimates of galaxy
SFRs and dust extinction. Optical spectra of SN Ia host galaxies are
fitted simultaneously for their stellar continua and emission lines
fluxes, from which we derive high-precision redshifts, gas-phase
metallicities, and Hα-based SFRs. With these data we show that
SN Ia host galaxies present tight agreement with the fiducial galaxy
mass-metallicity relation from Sloan Digital Sky Survey (SDSS) for
stellar masses log(M*/M☉)>8.5 where the relation is well
defined. The star formation activity of SN Ia host galaxies is
consistent with a sample of comparable SDSS field galaxies, though
this comparison is limited by systematic uncertainties in SFR
measurements. Our analysis indicates that SN Ia host galaxies are, on
average, typical representatives of normal field galaxies.
Description:
The SNeIa whose hosts are analyzed here were observed as part of the
ongoing science operations for the SNfactory (Aldering et al.
2002SPIE.4836...61A 2002SPIE.4836...61A). From 2005 to 2008, the SNfactory conducted a
wide-field search of the northern and equatorial sky using the
QUEST-II CCD camera on the Samuel Oschin 1.2m Schmidt telescope on
Mount Palomar, California.
Spectroscopic typing of search candidates and follow-up observations
of SNeIa were obtained with SNIFS (Lantz et al. 2004SPIE.5249..146L 2004SPIE.5249..146L),
mounted continuously on the University of Hawaii 2.2m telescope on
Mauna Kea.
This work analyzes all SNeIa discovered or followed by SNfactory, a
total of 469 SNeIa observed from 2004 to 2010. Of these SNeIa, a total
of 216 were extensively followed with SNIFS, with 185 of those being
discovered by the SNfactory search.
Photometric data for SNfactory SNIa host galaxies were gathered from
public sources (SDSS, 2MASS, UKIDSS, GALEX) as well as our own
targeted observations: we obtained optical photometry using SNIFS in
imaging mode.
Longslit spectra for our SNIa host galaxies were obtained during
numerous observing runs at multiple telescopes from 2007 to 2011. The
instruments used were the Kast Double Spectrograph on the Shane 3m
telescope at Lick Observatory, the LRIS on the Keck I 10m telescope on
Mauna Kea, the R-C Spectrograph on the Blanco 4m telescope at Cerro
Tololo Inter-American Observatory, the Goodman High Throughput
Spectrograph on the Southern Astrophysical Research (SOAR) 4m
telescope on Cerro Pachon, and GMOS-S on the Gemini-S 8m telescope on
Cerro Pachon.
