This program combines MIPS and IRAC imaging and MIPS and IRS spectroscopy (where available) of a sample of nearby starburst galaxies, over a range of metallicity and luminosity that includes the lowest metallicity galaxies known. These galaxies are near enough that groundbased support data already exist for many of them and they are bright enough that observing them does not take much time (except for the lowest metallicity galaxies). These data will be combined with new groundbased data and data from the literature to constrain a suite of starburst models. The models will provide the age and intensity of the burst that is consistent with the observations over a broad range of wavelengths and could be used to predict the subsequent evolution of the galaxy properties. Furthermore, this extremely detailed study of a small sample of starburst galaxies would provide the insight required to interpret observations of more distant galaxies (such as in the cosmological surveys) where we may only have a few photometric data points.
