cds-question@unistra.frradio-sourcesinfrared-photometryIn this paper we present near-infrared K-band imaging of a sample of ultra-steep-spectrum (USS) radio sources selected at 74-MHz. The dual selection criteria of low frequency and USS mean that we should be sensitive to the highest-redshift (z>5) radio galaxies. We have obtained K-band magnitudes for all of the objects in our sample of 26 and discuss the properties of each.2004MNRAS.355...20Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/355/20CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/435/863 : B3-VLA sample.
