An HI Study of Star-Forming Dwarf Galaxies

We prop ose an HI study of a unique, complete sample of 26 star-forming dwarf galaxies for which we have unsurpassed multi-wavelength supp orting data from visible to mid-infrared wavelengths. Measuring the HI content will add crucial information regarding the fuel reservoir to our existing knowledge of stellar mass and dust content in these systems. Sp ecifically, it will characterize the gas-to-dust and gas-to-stars ratios. In addition, we will use the sp ectra to measure dynamical masses for the systems in order to b etter understand the connection b etween these lo cal, low-mass systems and the infrared-faint Lyman-Break Galaxies detected by the Spitzer Space Telescop e (Huang et al. 2005).
