Absorption lines in quasar spectra allow us to study intervening galaxies. Narrow-band imaging centered at redshifted H-alpha or [O II] emission at the absorber redshift, along with corresponding broad-band images, can be employed in order to isolate the absorbers from the quasar. Images obtained
in narrowband and broadband filters using the NASA Goddard Fabry-Perot imager and Near-Infrared camera at Apache Point Observatory (APO) for this purpose are presented. We will also present analysis of Gemini GMOS spectra obtained for some candidate absorber galaxies. These data allow us to search for the galaxies and constrain their star formation rates (SFRs), luminosities, and metallicities based on emission line measurements. These quantities will be compared with the cosmic star formation history in order to better understand the role of quasar absorbers in galactic evolution.
