We measure velocity offsets in the NaI \lambda\lambda5890, 5896 (Na D) interstellar medium absorption lines to track how neutral galactic winds change as their host galaxies evolve. Our sample of \sim80,000 SDSS spectra at 0.010 < z < 0.325 includes starburst, post-starburst, and quiescent galaxies, forming an evolutionary sequence of... Show more
