cds-question@unistra.fractive-galactic-nucleiinterferometrypolarimetryradio-continuum-emissionradio-sourcesWe observed 51 sources in the Q-U-I JOint TEnerife (QUIJOTE) cosmological fields which were brighter than 1Jy at 30GHz in the Planck Point Source Catalogue (version 1), with the Very Large Array at 28-40GHz, in order to characterise their high-radio-frequency variability and polarization properties. We find a roughly log-normal distribution of polarization fractions with a median of 2%, in agreement with previous studies, and a median rotation measure (RM) of ~1110rad/m^2^ with one outlier up to ~64000rad/m^2^ which is among the highest RMs measured in quasar cores. We find hints of a correlation between the total intensity flux density and median polarization fraction. We find 59% of sources are variable in total intensity, and 100% in polarization at 3{sigma} level, with no apparent correlation between total intensity variability and polarization variability. This indicates that it will be difficult to model these sources without simultaneous polarimetric monitoring observations and they will need to be masked for cosmological analysis.2021MNRAS.502.4779Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/502/4779CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/91 : Planck Catalog of Compact Sources Release 1 (Planck, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/502/4779https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/502/4779http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/502/4779https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/502/4779https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/502/4779http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/502/4779GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/502/4779/table4 (28-40GHz variability and polarimetry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/502/4779/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/502/4779/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/502/4779/table4?GETtext/xml+votable180.050000true133.70362520.10850.0055555555555555566/514 532 556 579 700 911 2143 2214 2414 2836 2844 4695 4820 4940 5139 5448 5546 5597 5693 5767 5817 6496 6507 7389 7570 7623 7642 7653 7969 9442 9460 9545 9633 9676 9723 9998 10163 11430 11715 11845 13410 14150 15067 15286 16027 16059 18035 18378 19567 19622 200992.2528636539047234e-23 2.2528636539047234e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/502/4779?format=asciiRadiodefaultJ/MNRAS/502/4779/table428-40GHz variability and polarimetrySimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
