Roughly half of the present-day elliptical galaxies have formed since z=1, as a yet-unknown physical process caused the cessation of star formation and led galaxies to migrate from the blue, star-forming population to the red sequence. The prevailing scenario is that an elliptical is the likely end result of a merger of two star-forming disk galaxies, which may create a starburst and/or ignite a quasar. It remains unclear whether the bulk of the gas in the disk galaxies is consumed during the starburst phase and/or expelled from the remnant. We propose to observe post-starburst galaxies at z=0.2 and z=0.8 with the blue-sensitive LRIS on Keck-I to look for relic large-scale outflowing galactic winds, detected through blue-shifted UV ISM absorption lines. We will measure evolution of the prevalence and velocities of outflowing winds in these transition galaxies, to determine: (1) whether winds are frequently found in post-starbursts at both redshifts, suggesting that winds are required to expel the gas; and (2) whether the velocities indicate a starburst or AGN-driven wind.
