| Probing the Universe with Quasar Absorption Lines | |
| Since star formation implies the conversion of gas into stars, a successful theory of galaxy formation requires an understanding of the properties and evolution of the gaseous components of the Universe along with the dark matter and stellar components. In this talk, the method of using absorption lines in the spectra of background quasars to study cosmologically-distant gaseous structures and their environments will be discussed. Investigations of the neutral gas component from low to high redshift will be highlighted. Some emphasis will be placed on progress that can be made through the use of Sloan Digital Sky Survey data. | |
