Evolution of the Gaseous Content of the Universe
Abstract
Results of a new spectroscopic survey for damped Ly-alpha absorption systems conducted at ultraviolet wavelengths are combined with those of previous surveys conducted at optical wavelengths in order to examine the evolution of the gaseous contnet of the universe at 0<~z<~3.5. Implicaitons for scenarios of galaxy formation and evolution are discussed. (SECTION: The Second Hubble Fellows Symposium)
