Outflows have been used to explain the mass-metallicity relation, the star formation history of the universe, and the shape of the baryonic mass function. However, few studies have focused on the basic question of how outflow velocities depend upon the physical properties of their host galaxies. Here we propose an archival project utilizing 52 COS spectra of local star-forming galaxies spanning four decades of star formation rate, and stellar mass. We will preform a self-consistent analysis of trends between galactic properties (star formation rate, stellar mass, specific star formation rate and star formation rate surface density) and outflow velocities measured from interstellar metal absorption lines (e.g., CII 1335). We will extend this analysis to different gas phases -- cold, warm, and hot -- to gain a more comprehensive understanding of the physics of multi-phase outflows. The trends we observe will provide insights into the feedback process and will be crucial new benchmarks for simulations. ISM IN EXTERNAL GALAXIES Default Medium false true false false false SUPPORTED
