cds-question@unistra.frgalaxiesradio-sourcesWe present optical and infrared broad-band images, radio maps, and optical spectroscopy for the nuclear region of a sample of nearby galaxies. The galaxies have been drawn from a complete volume-limited sample for which we have already presented X-ray imaging. We modelled the stellar component of the spectroscopic observations to determine the star formation history of our targets. Diagnostic diagrams were used to classify the emission-line spectra and determine the ionizing mechanism driving the nuclear regions. All those sources classified as active galactic nuclei present small Eddington ratios (~10^-3^-10^-6^), implying a very slow growth rate of their black holes. We finally investigate the relative numbers of active and normal nuclei as a function of host galaxy luminosity and find that the fraction of active galaxies slowly rises as a function of host absolute magnitude in the MB~-12 to -22 range.2007MNRAS.382.1552Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/382/1552CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/382/1552https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/382/1552http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/382/1552https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/382/1552https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/382/1552http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/382/1552GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/382/1552/table1 (The volume-limited sample of galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/382/1552/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/382/1552/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/382/1552/table1?GETtext/xml+votable180.050000true8.348.508330.005555555555555556Cone search capability for table J/MNRAS/382/1552/table5 (Coordinates and classification for the sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/382/1552/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/382/1552/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/382/1552/table5?GETtext/xml+votable180.050000true8.293958348.50944440.0055555555555555566/2155 2282 2622 2709 2774 2777 3299 3304 3506 3558 5978 7602 7604 7606 7743 7878 8028 10856 10888 10941 11084 11127 11227 11434 11639 11961 15592 16441 16655 16701 28015 28091 28521 28524 28535 43881https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/382/1552?format=asciiRadiodefaultJ/MNRAS/382/1552/refsReferencesComCommentsmeta.notecharrecnoRecord number assigned by the VizieR team.
