Discovery of a Pair of [CLC][ITAL]z[/ITAL][/CLC] = 4.25 Quasars from the Sloan Digital Sky Survey
We report the discovery of a pair of z = 4.25 quasars with a separation of 33''. The brighter of the two objects was identified as a high-redshift quasar candidate from Sloan Digital Sky Survey multicolor imaging data, and the redshift was measured from a spectrum obtained with the Hobby-Eberly …
