cds-question@unistra.fractive-galactic-nucleipolarimetrygalaxiesphotometryWe present results of a microvariability polarization study in the violently variable quasar 3C 279. We have resolved the polarization curves in the V band for this object down to timescales of minutes. We found two main components in the evolution of the degree of linear polarization, one consisting of a flicker with timescales of several tens of minutes and other component with far more significant variations on timescales of a few days. The linear polarization descended from ~17% down to ~8% in three nights. The polarization angle underwent a sudden change of more that 10 degrees in a few hours, perhaps indicating the injection of a new shock in the jet. The amplitude of the intranight flickering in the degree of polarization is at the level of ~1%. These are probably the best sampled polarization data ever obtained for this object. We also performed IR observations and we provide a follow-up of the evolution of this source at such energies after the main polarization outburst.2003A&A...409..857Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/409/857CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/409/857https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/409/857http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/409/857https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/409/857https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/409/857http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/409/857GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/409/857/table2Results from polarization observations of 3C 279recnoRecord number assigned by the VizieR team.
