VLA and VLBA Observations of the Highest Redshift Radio-Loud QSO J1427+3312 at z = 6.12
E. Momjian, C. L. Carilli, I. D. McGreer
We present 8.4 GHz VLA A-array and 1.4 GHz VLBA results on the radio continuum emission from the highest redshift radio-loud quasar known to date, the QSO J1427+3312. The…

Discovery of a z=6.1 Radio-Loud Quasar in the NDWFS
Ian D. McGreer, Robert H. Becker, David J. Helfand +1
From examination of only 4 deg^2 of sky in the NOAO Deep Wide-Field Survey (NDWFS) region, we have identified the first radio-loud quasar at a redshift z>6. The object, FIRST J1427…
