Scientific paper

We present the new results from a survey of i-dropout objects selected from the multicolor imaging data of the Sloan Digital Sky Survey (SDSS). Three new objects, at z=6.4, 6.2 and 6.05, were discovered, bringing the total number of known quasars at z>5.7 to seven. We present new measurements on the evolution of the quasar number density and quasar emission line strengths based on this quasar sample, and discuss the Gunn-Peterson effect along different lines of sight and its implications on the history of cosmic reionization based on observations taken with the Apache Point 3.5-m, Keck, and Hobby-Eberly and Calar Alto 3.5m Telescopes.
