- catalog abstract "Prof. Impey discusses the use of quasars as high redshift probes of the universe. Quasar absorption lines can be used to map out the IGM, trace the halos of high redshift galaxies, and survey the evolution of galaxy disks. The focus is on what can be learned from studying the Lyman-alpha forest when information is combined from quasar groupings closely separated in the sky.".
