We focus on galaxies that either host a low-luminosity AGN or have recently had their star formation quenched to test whether these galaxies have winds of sufficient velocity to potentially clear gas from the galaxy. We find, using absorption features of Fe II, Mg II, and Mg I, that six of our X-ray AGN host galaxies and four of our post-starburst galaxies have outflowing galactic winds, with typical velocities of ~200 km/s. We additionally find that most of the galaxies in our sample show line emission, presumably from the wind, in either Fe II* or Mg II. A total of 100% of our X-ray AGN host sample (including four red sequence galaxies) and 77% of our post-starburst sample has either blueshifted absorption or line emission from a wind. We conclude that while outflowing galactic winds are extremely common in both X-ray low-luminosity AGN host galaxies and post-starburst galaxies at intermediate redshifts, the winds are likely driven by supernovae (as opposed to AGN) and do not appear to have sufficiently high velocities to quench star formation in these galaxies.
