cds-question@unistra.frradio-galaxiesradio-continuum-emissionWe present radio continuum observations at frequencies ranging from ~150 to 5000MHz of the misaligned double-double radio galaxy (DDRG) 3C 293 (J1352+3126) using the Giant Metrewave Radio Telescope (GMRT) and the Very Large Array (VLA). The spectra of the outer lobes and the central source are consistent with being straight, indicating spectral ages of <~17-23Myr for the outer lobes and <~0.1Myr for the central source. The north-western lobe has a prominent hotspot suggesting that the interruption of jet activity is <~0.1Myr, consistent with the age of the inner double. The time-scale of interruption of jet activity appears significantly smaller than observed in most other DDRGs which are often associated with giant radio sources. These observations suggest that there is a wide range of time-scales of interruption of jet activity in active galaxies.2011MNRAS.414.1397Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/414/1397CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/395/269 : ELAIS-N1 field 325MHz observations (Sirothia+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/414/1397https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/414/1397http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/414/1397https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/414/1397https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/414/1397http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/414/1397GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/414/1397/tablea1 (Sources within 2.2{deg} of the phase centre of the GMRT observations at 154MHz (HPBW~3.1{deg}))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/414/1397/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/414/1397/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/414/1397/tablea1?GETtext/xml+votable180.050000true205.533531.32572220.0055555555555555565/2582 2585 2588-2590 6/10319 10334 10348-10349 10351 103641.0204147082982102e-25 1.0204147082982102e-25https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/414/1397?format=asciiRadiodefaultJ/MNRAS/414/1397/tablea1Sources within 2.2{deg} of the phase centre of the GMRT observations at 154MHz (HPBW~3.1{deg})recnoRecord number assigned by the VizieR team.
