Abstract

We present spectra for 14 high-redshift (0.17Much of the data presented herein were obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California, and the National Aeronautics and Space Administration. The Observatory was made possible by the generous financial support of the W. M. Keck Foundation. Also based in part on observations made with the European Southern Observatory telescopes (ESO programs 58.A-0745 and 59.A-0745).
