Title: A z=0.633 galaxy that may be both a DLA absorber and a LAE

Abstract: To fully understand galaxy formation, processes involving the conversion of gas into stars must be probed. By studying the stellar+emission properties of gas-rich quasar absorbers, one can bridge these components. We've built a sample of Damped Lyman Alpha (DLA) Absorbers at z~0.6 from HST prism spectroscopy. The prism images also provide DLA galaxy candidates at small impact parameters from the quasars. Using X-Shooter on the VLT, we successfully identified 7 new DLA galaxies out of 9 searched. But the brightest one was not detected in our X-Shooter observations. This can be explained if it's a Lyman Alpha Emitter (LAE) at the DLA redshift. With short GMOS IFU observations, we propose to study this galaxy. As the lowest-z LAE known, it may also prove to be a unique identification for a DLA galaxy.
