Richards,Donald P. Schneider,Chris Stoughton,Alexander S. Szalay,Anirudda R. Thakar,D. G. York +29 more
TL;DR: In this article, moderate resolution Keck spectroscopy of quasars at z=5.82, 5.99 and 6.28 was presented, and it was shown that the Ly Alpha absorption in the spectra evolves strongly with redshift.
