A new search for distant radio galaxies in the Southern hemisphere - II. 2.2 <i>μ</i>m imaging*
We have compiled a sample of 234 ultra-steep-spectrum (USS) selected radio sources in order to find high-redshift radio galaxies. The sample covers the declination range −40° < δ < −30° in the overlap region between the 1400-MHz National Radio Astronomy Observatory (NRAO) Very Large Array (VLA) Sky Survey (NVSS), 408-MHz …
