Description
Low mass, low metallicity galaxies are the most likely source of the photons that
reionized the universe, but the relationships between low metallicity star formation,
galactic outflows, and the escape of ionizing radiation at high redshifts are still
unclear. Using rest-frame UV and optical spectra of lensed and unlensed low
metallicity galaxies at z~2, I will discuss constraints on the velocity and
ionization state of outflows, the rate and geometry of star formation, and the
covering fraction and column density of neutral hydrogen.
