摘要：
We present the results of detailed studies of the astrophysical conditions in z similar to 3 Lyman Break Galaxies (LBGs), with particular emphasis on what can be learned from LBG rest frame UV spectra. By drawing from our database of similar to 1000 spectra, and constructing high S/N composite spectra from galaxies grouped according to properties such as Lyalpha profile, kinematics, luminosity, and extinction, we show how the rest frame UV spectroscopic properties systematically depend on other galaxy properties. Such information is crucial to understanding the detailed nature of LBGs and their impact on the surrounding inter-galactic medium (IGM).
