DISCOVERY OF A RADIO-SELECTED z similar to 6 QUASAR
The Astrophysical journal, v 736(1)
20 Jul 2011
Abstract
We present the discovery of only the second radio-selected z similar to 6 quasar. We identified SDSS J222843.54+011032.2 (z = 5.95) by matching the optical detections of the deep Sloan Digital Sky Survey Stripe 82 with their radio counterparts in the Stripe 82 Very Large Array Survey. We also matched the Canadian-France-Hawaiian Telescope Legacy Survey Wide with the Faint Images of the Radio Sky at Twenty cm survey but have yet to find any z similar to 6 quasars in this survey area. The discovered quasar is optically faint, z = 22.3 and M-1450 similar to -24.5, but radio bright, with a flux density of f(1.4 GHz,peak) = 0.31 mJy and a radio loudness of R similar to 1100 (where R f(5 GHz)/f(2500)). The i - z color of the discovered quasar places it outside the color selection criteria for existing optical surveys. We conclude by discussing the need for deeper wide-area radio surveys in the context of high-redshift quasars.
