Abstract
We present results of a new, large survey for high-redshift radio-loud quasars, which targets quasars with . The survey is based on the PMN and NVSS radio surveys, optically identified using digitised UKST B, R and I plates. Six new flat-spectrum QSOs have been discovered, and one previously known QSO rediscovered, based on their red optical colours. The QSOs discovered in this survey are bright in both radio and optical bands; in particular PMN J1451-1512 (, , ) and PMN J0324-2918 (, ) are very luminous. PMN J1451-1512 at is also now the most distant radio-selected quasar. In addition, 9 new quasars with were discovered during the survey. We present spectra and finding charts for the new quasars. We also derive a surface density of for flat-spectrum QSOs with mJy and mag.
