Jansky Very Large Array observations of a complete sample of radio galaxies selected at 15.7GHz from the Tenth Cambridge (10C) survey. 67 out of the 95 sources (71 per cent) are unresolved in the new observations and lower frequency radio observations, placing an upper limit on their angular size of ~2arcsec. Thus, compact radio galaxies, or radio galaxies with very faint jets, are the dominant population in the 10C survey. This provides support for the suggestion in our previous work that low-luminosity (L<10^25^WHz^-1^) radio galaxies are core dominated, although higher resolution observations are required to confirm this directly. The 10C sample of compact, high-frequency selected radio galaxies is a mixture of high-excitation and low-excitation radio galaxies and displays a range of radio spectral shapes, demonstrating that they are a mixed population of objects.2020MNRAS.493.2841Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/493/2841CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/429/2080 : Lockman Hole 10C sources radio spectral indicesJ/MNRAS/453/4244 : Faint radio source population at 15.7GHz (Whittam+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/493/2841https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/493/2841http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/493/2841https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/493/2841https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/493/2841http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/493/2841GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/493/2841/table1 (Properties of the sources in this based on the new VLA observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/493/2841/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/493/2841/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/493/2841/table1?GETtext/xml+votable180.050000true160.8354791758.939105560.0055555555555555566/6047 6069 6071 6077 6079 6090 6112 61142.483060040379131e-20 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/493/2841?format=asciiOpticalInfraredRadiodefaultJ/MNRAS/493/2841/table1Properties of the sources in this based on the new VLA observationsSimbadNameSimbad column added by the CDSmeta.idcharnullableNcompNumber of components source is resolved intometa.numberintrecnoRecord number assigned by the VizieR team.
