We use GALEX NUV and FUV imaging of nearby supernova Ia (SN Ia) hosts to study the spatial correlation of SNe Ia with star formation. Our aim is to constrain the timescale between progenitor formation and SN Ia explosion using multi-wavelength imaging that traces progenitor populations of different ages. Recent models consisting of two components for SN Ia production include a large, prompt component correlated with star formation, as well as an additional delayed component correlated with mass. By comparing the GALEX UV--SN Ia correlation, which traces star formation at timescales 1Gyr, with the Hα correlation, tracing star formation at timescales of 10Myr, and the IR correlation, tracing mass, we provide a nearby estimate of the relative sizes and timescales for the two components.
GALEX (Galaxy Evolution Explorer) is a NASA Small Explorer, launched in April 2003. We gratefully acknowledge NASA's support for construction, operation, and science analysis for the GALEX mission.
