Title: Gas and Galaxies in the Cosmic Web

Abstract: We propose to measure the distribution and properties of the gas in the IGM and Circum-Galactic Medium (CGM), and galaxies located in the same volume. We will use Gemini/GMOS to obtain spectroscopic data of galaxies between 0<z<0.4 around QSO sightlines that have high quality HST/COS far-UV spectroscopy, for which we have direct access. This GMOS dataset corresponds to a fundamental part of a larger gas/galaxy survey carried out by our collaboration. The final survey will assemble galaxy data from SDSS, 6dF, HYDRA, and GMOS around HST/COS targeted sightlines aiming to map the `Cosmic Web' in both gas and galaxies at unprecedented quality. Using this dataset we will be able to investigate the gas/galaxy connection (including feedback processes), its dependence on galaxy environment and its evolution with cosmic time. We will also refine the local baryon census and measure the metallicity of gas in voids.
