Abstract

We present the results from a survey of i -dropout objects selected from ∼1550 deg 2 of multicolor imaging data from the Sloan Digital Sky Survey to search for luminous quasars at z ≳ 5.8. Objects with i *- z * > 2.2 and z * 0.90. The ARC 3.5 m spectrum of SDSSp J103027.10+052455.0 shows that over a...
