Outflows in Infrared-Luminous Starbursts at z < 0.5. II. Analysis and Discussion 123

By David S. Rupke, Sylvain Veilleux and D. B. Sanders


We have performed an absorption-line survey of outflowing gas in 78 starburstdominated, infrared-luminous galaxies. This is the largest study of superwinds at z � 3. Superwinds are found in almost all infrared-luminous galaxies, and changes in detection rate with SFR–winds are found twice as often in ultraluminous infrared galaxies (ULIRGs) as in less-luminous galaxies–reflect different wind geometries. The maximum velocities we measure are 600 km s −1, though most of the outflowing gas has lower velocities (100 − 200 km s −1). (One galaxy has velocities exceeding 1000 km s −1.) Velocities in LINERs are higher than in H II galaxies, and outflowing ionized gas often has higher velocities than the neutral gas. Wind properties (velocity, mass, momentum, and energy) scale 1 Some of the observations reported here were obtained at the W. M. Keck Observatory, which is operate
