We have used the ultraviolet all-sky imaging survey currently being conducted by the Galaxy Evolution Explorer (GALEX) to identify for the first time a rare population of low-redshift starbursts with properties remarkably similar to high-redshift Lyman Break Galaxies. These compact UV-luminous galaxies (UVLGs) resemble Lyman Break Galaxies in terms of size, UV luminosity, surface brightness, mass, metallicity, kinematics, and color. They have characteristic "ages" (stellar mass/SFR) of only a few hundred Myr. This population of galaxies is thus worthy of study in its own right and as a sample of local analogs of Lyman Break Galaxies. We propose to obtain far-infrared and mid-infrared fluxes for a sample of the 31 nearest and brightest compact UVLGs using MIPS and IRAC. With these data we will 1) determine the total star formation rate using the far-IR+UV luminosity, 2) probe the dust content and the relation between UV reddening and IR flux in these galaxies, 3) explore the relationship between PAH emission features and star-formation rates in the extreme environment of UVLGs, 4) construct the IR to UV SED and compare with extensive spectral evolution models to determine the star formation history and total stellar mass, and 5) calibrate techniques to study the properties of high-redshift Lyman Break Galaxies. These data will provide important information on star formation in the present-day universe, and will shed new light on the earliest major episodes of star formation in high-redshift galaxies.
