- catalog abstract "Dr. Bechtold presents findings from three projects from which quasar absorption line spectra were obtained, a ground based project at the MMT, anad two space based projects using the Hubble Space Telescope and the Chandra Telescope. She presents findings which confirm previous results and allow researchers to determine the evolution of the Lyman alpha forest, the clustering of absorption lines, the evoltuion of the ionizing UV background and the distribution of C IV in the Milky Way.".
