cds-question@unistra.frquasarsvery-long-baseline-interferometryradio-sourcesgalaxy-classification-systemsNRAO 530 is an optically violent variable source and has been studied with multi-epoch multifrequency high-resolution very long baseline interferometry (VLBI) observations. NRAO 530 was monitored with the Very Long Baseline Array (VLBA) at three frequencies (22, 43 and 86GHz) on 10 consecutive days in 2007 May during observations of the Galactic Centre (Sgr A*). Furthermore, analysis of archival data of NRAO 530 at 15GHz over the last 10 years allows us to study its detailed jet kinematics. We identified the compact component located at the southern-end of the jet as the VLBI core, consistent with previous studies.2011MNRAS.418.2260Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/418/2260CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/418/2260https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/418/2260http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/418/2260https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/418/2260https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/418/2260http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/418/2260GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalRadiodefaultJ/MNRAS/418/2260/table8Description of VLBA images of NRAO 530 shown in Fig. 14 and Fig. 15recnoRecord number assigned by the VizieR team.
