C. Tremonti, in collaboration with J. Moustakas (NYU) and Aleks Diamond-Stanic (Steward), is looking for empirical evidence of quasar feedback by searching for signs of cold gas outflows in galaxies that have recently undergone a major merger. We identify candidate galaxies in the SDSS by looking for galaxies at z=0.4 - 0.8 with post-starburst spectral features -- strong stellar Balmer absorption lines and weak nebular emission lines. We follow up these galaxies with the 6.5-m MMT telescope to obtain high S/N spectra suitable for identifying absorption from interstellar Mg II (rest wavelength 2800 A). We have detected unusually fast gas outflows (> 1000 km/s) in 2/3 of our sample. We are in the process of obtaining higher resolution data with MIKE on Magellan to estimate the mass of gas in the outflows. C. Tremonti, in collaboration with Y. Yang (Steward) and A. Zabludoff (Steward) is developing a new technique to accurately measure the age of post-starburst galaxies. (Age = time since the last major burst of star formation.) This is accomplished by combining state of the art stellar population synthesis models with ultraviolet data from the GALEX satellite and optical photometry and spectroscopy from the SDSS. The improved age estimates will be used to understand the evolution of gas outflows and AGN activity following the major interaction-induced burst of star formation.
