cds-question@unistra.fractive-galactic-nucleiradio-galaxiesStandard galaxy formation models predict that large-scale double-lobed radio sources, known as DRAGNs, will always be hosted by elliptical galaxies. In spite of this, in recent years a small number of spiral galaxies have also been found to host such sources. These so-called spiral DRAGNs are still extremely rare, with only ~5 cases being widely accepted. Here we report on the serendipitous discovery of a new spiral DRAGN in data from the Giant Metrewave Radio Telescope (GMRT) at 322MHz. The host galaxy, MCG+07-47-10, is a face-on late-type Sbc galaxy with distinctive spiral arms and prominent bulge suggesting a high black hole mass. Using WISE infra-red and GALEX UV data we show that this galaxy has a star formation rate of 0.16-0.75M_{sun}_/yr, and that the radio luminosity is dominated by star-formation. We demonstrate that this spiral DRAGN has similar environmental properties to others of this class, but has a comparatively low radio luminosity of L_1.4GHz_=1.12x10^22^W/Hz, two orders of magnitude smaller than other known spiral DRAGNs. We suggest that this may indicate the existence of a previously unknown low-luminosity population of spiral DRAGNS.2016A&A...595L...8Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/595/L8CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/595/L8https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/595/L8http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/595/L8https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/595/L8https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/595/L8http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/595/L8GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/595/L8/list (Information of fits files)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/595/L8/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/595/L8/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/595/L8/list?GETtext/xml+votable180.050000true349.9842143.251370.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/595/L86/13761https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/595/L8?format=asciiRadiodefaultJ/A+A/595/L8/listInformation of fits filesrecnoRecord number assigned by the VizieR team.
