Abstract:
We use multi-wavelength, matched aperture, integrated photometry from
the Galaxy Evolution Explorer (GALEX), the Sloan Digital Sky Survey,
and the RC3 to estimate the physical properties of 166 nearby galaxies
hosting 168 well-observed Type Ia supernovae (SNe Ia). The ultraviolet
(UV) imaging of local SN Ia hosts from GALEX allows a direct
comparison with higher-redshift hosts measured at optical wavelengths
that correspond to the rest-frame UV. Our data corroborate well-known
features that have been seen in other SN Ia samples. Specifically,
hosts with active star formation produce brighter and slower SNe Ia on
average, and hosts with luminosity-weighted ages older than 1Gyr
produce on average more faint, fast, and fewer bright, slow SNe Ia
than younger hosts. New results include that in our sample, the
faintest and fastest SNe Ia occur only in galaxies exceeding a stellar
mass threshold of ∼1010M☉, leading us to conclude that their
progenitors must arise in populations that are older and/or more metal
rich than the general SN Ia population.
