cds-question@unistra.fractive-galactic-nucleigalaxiesgalaxy-classification-systemsWe investigated the properties of the host galaxies of active galactic nuclei (AGNs). We used radio emission around the nuclei of the host galaxies to represent AGN activity and used infrared (IR) emission to represent the star-forming activity and stellar population of the host galaxies. We determined that active galaxies have higher stellar masses (SMs) within the central kiloparsec radius than normal galaxies do independent of the Hubble types of the host galaxies; but both active and normal galaxies exhibit similar specific star formation rates (SSFRs), ranging between 10^-10.5^ and 10^-9.5^/yr. We find that the central SM surface density might be used as an indicator to identify AGNs. We also discovered that certain AGNs exhibit substantial inner stellar structures in the IR images; most of the AGNs with inner structures are Seyferts, whereas only a few LINERs exhibit inner structures. We note that the AGNs with inner structures show a positive correlation between the radio activity of the AGNs and the SFRs of the host galaxies, but the sources without inner structures show a negative correlation between the radio power and the SFRs. These results might be explained with a scenario of starburst-AGN evolution. In this scenario, AGN activities are triggered following a nuclear starburst; during the evolution, AGN activities are accompanied by SF activity in the inner regions of the host galaxies; at the final stage of the evolution, the AGNs might transform into LINERs, exhibiting weak SF activity in the central regions of the host galaxies.2015AJ....150...43Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/150/43CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/145 : Nearby Galaxies Catalogue (NBG) (Tully 1988)J/ApJS/133/77 : VLA radio continuum survey of Seyfert galaxies (Ho+, 2001)J/ApJ/378/65 : 8.4GHz observations of compact starbursts (Condon+ 1991)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/150/43https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/150/43http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/150/43https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/150/43https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/150/43http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/150/43GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/150/43/table1 (List of active galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/150/43/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/150/43/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/150/43/table1?GETtext/xml+votable180.050000true68.29623175.35433890.005555555555555556Cone search capability for table J/AJ/150/43/table2 (List of nearby normal galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/150/43/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/150/43/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/150/43/table2?GETtext/xml+votable180.050000true2.193416715.81552780.0055555555555555566/231 295 650 700 816 941 1008 1701 2121 2130 2142 2251 2282 2320 2324 2372 2774 3506 4439 4511 4993 5061 5142 5174 5203 5523 5545 5636 5715 5751 5816 5975 5978 6604 6605 6623 6977 7132 7214 7225 7241 7246 7424 7552 7602 7607 7642 7659 7713 7869 7878 7921 7941 8492 8673 8922 8997 9882 9895 10144 10210 10364 10465 10475 10755 10761 10778 10799 10817 10841 10847 10856 10888 10897 10900 10901 10905 10911 10912 10924 10925 10935 10941 10954 10959 10976 10977 10979 10986 11027 11029 11030 11101 11127 11143 11227 11375 11434 11448 11681 11908 11965 12047 12306 13401 13489 16098 16441 16595 16605 16755 17183 17506 17525 17754 18011 18398 18406 18783 18794 18897 19125 19283 19619 19678 20208 20270 20526 21026 23075 23171 23323 24896 24912 25054 25518 25790 25907 26260 26265 26271 26294 26309 26313 26338 26365 26803 27512 27514 27515 27518 27591 27604 27643 27719 27721 27765 27767 27773 27857 27914 27918 27938 27942 27945 27955 28039 28054 28077 28087 28091 28126 28141 28147 28188 28491 28495 28496 28498 28517 28524 28535 28538 28593 28608 28609 28610 28612 28631 31158 31259 33193 33228 33268 33656 33832 33935 33986 34294 34361 34401 34403 34471 34638 34641 35243 35447 35993 36188 36618 36785 36861 36974 37436 38268 38390 38655 40221 40410 41586 42016 43339 43420 43677 43748 43874 43877 43878 43881 44448 44660 45746 45914 45937 46399 46442 46460 46568 46615 46811 47047https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/150/43?format=asciiOpticaldefaultJ/AJ/150/43/table1List of active galaxiesSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
