cds-question@unistra.fractive-galactic-nucleiradio-galaxiesgalaxy-classification-systemsPowerful radio galaxies exist as either compact or extended sources, with the extended sources traditionally classified by their radio morphologies as Fanaroff-Riley (FR) type I and II sources. FRI/FRII and compact radio galaxies have also been classified by their optical spectra into two different types: high excitation (HERG; quasar-mode) and low excitation (LERG; jet-mode). We present a catalogue of visual morphologies for a complete sample of >1000 1.4-GHz-selected extended radio sources from the Sloan Digital Sky Survey. We study the environment and host galaxy properties of FRI/FRII and compact sources, classified into HERG/LERG types, in order to separate and distinguish the factors that drive the radio morphological variations from those responsible for the spectral properties. Comparing FRI LERGs with FRII LERGs at fixed stellar mass and radio luminosity, we show that FRIs typically reside in richer environments and are hosted by smaller galaxies with higher mass surface density; this is consistent with extrinsic effects of jet disruption driving the Fanaroff-Riley (FR) dichotomy. Using matched samples of HERGs and LERGs, we show that HERG host galaxies are more frequently star forming, with more evidence for disc-like structure than LERGs, in accordance with currently favoured models of fundamentally different fuelling mechanisms. Comparing FRI/FRII LERGs with compact LERGs, we find the primary difference is that compact objects typically harbour less massive black holes. This suggests that lower mass black holes may be less efficient at launching stable radio jets, or do so for shorter times. Finally, we investigate rarer sub-classes: wide-angle-tailed, head-tail, FR-hybrid and double-double sources.2017MNRAS.466.4346Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/466/4346CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/466/4346https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/466/4346http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/466/4346https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/466/4346https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/466/4346http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/466/4346GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/466/4346/table1 (Properties of the 1329 extended radio galaxies with z>0.03)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/466/4346/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/466/4346/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/466/4346/table1?GETtext/xml+votable180.050000true149.1698761-0.023340.005555555555555556Cone search capability for table J/MNRAS/466/4346/table4 (Properties of FR radio galaxies and compact radio sources used in our analysis)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/466/4346/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/466/4346/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/466/4346/table4?GETtext/xml+votable180.050000true176.2771853.6480.0055555555555555564/1135 1232 1244 1247 5/546 553 555 558 641 643-645 647-648 651 654-655 665-668 671 676-677 689 692 714-715 736 739-740 742-743 754-755 758-759 930 4400 4505-4507 4517 4522 4530-4531 4533 4535 4537 4578 4584-4585 4587 4590 4885 4887 4932-4933 4936-4937 4939 4941-4942 4946 4952 4954-4955 4958-4959 4964 4980 4982-4984 4987 6/2090 2178-2179 2188 2190 2208-2210 2217-2219 2224 2226-2227 2230 2236 2238 2560-2562 2570-2571 2584 2587 2596-2597 2599 2608-2609 2611-2614 2627 2632-2633 2638-2639 2657-2659 2678-2679 2681-2682 2693 2695 2713 2717 2752-2753 2760-2761 2764-2765 2773-2775 2777 2780 2782-2783 2851 2854 2872-2873 2875 2878-2879 2920-2922 2939 2942 2948-2949 2952-2953 2955 2964-2966 3008 3010-3011 3013-3015 3026-3027 3030-3031 3040 3057 3061 3712 3718-3719 3744 17213 17256 17258 17260 17262-17263 17344 17349 17360 17405 17407 17471 17512 17514 17608-17609 17661-17663 17832 17834-17835 17950-17951 17969 17972-17973 17975 17981-17983 17994-17995 18004 18016-18018 18040 18042-18043 18046 18077 18082-18083 18092 18094 18114-18116 18118-18119 18129-18131 18137-18139 18144-18145 18147 18156-18157 18159 18176 18178 18307 18318-18319 18344-18346 18354 18366-18367 19456-19457 19536-19537 19539 19736-19738 19740 19743 19761-19763 19772-19774 19778 19790 19814-19815 19824 19826 19845 19860 19862-19863 19865 19868-19869 19871 19924 19926 19940-19942 20293 20306-20310 20313 20319https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/466/4346?format=asciiOpticalRadiodefaultJ/MNRAS/466/4346/table1Properties of the 1329 extended radio galaxies with z>0.03SimbadNameSimbad column added by the CDSmeta.idcharFiberSDSS fiber IDmeta.id;meta.mainintrecnoRecord number assigned by the VizieR team.
