cds-question@unistra.frgalaxiesinfrared-photometrygalaxy-classification-systemsWe investigate scaling relations of bulges using bulge-disk decompositions at 3.6um and present bulge classifications for 173 E-Sd galaxies within 20Mpc. Pseudobulges and classical bulges are identified using Sersic index, Hubble Space Telescope morphology, and star formation activity (traced by 8um emission). In the near-IR pseudobulges have n_b_<2 and classical bulges have n_b_>2, as found in the optical. Sersic index and morphology are essentially equivalent properties for bulge classification purposes. We confirm, using a much more robust sample, that the Sersic index of pseudobulges is uncorrelated with other bulge structural properties, unlike for classical bulges and elliptical galaxies. Also, the half-light radius of pseudobulges is not correlated with any other bulge property. We also find a new correlation between surface brightness and pseudobulge luminosity; pseudobulges become more luminous as they become more dense.2010ApJ...716..942Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/716/942CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/155 : Third Reference Cat. of Bright Galaxies (RC3) (de Vaucouleurs+ 1991)VII/145 : Nearby Galaxies Catalogue (NBG) (Tully 1988)J/ApJS/182/216 : Surface photometry of Virgo ellipticals (Kormendy+, 2009)J/AJ/136/773 : Structure of classical bulges and pseudobulges (Fisher+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/716/942https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/716/942http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/716/942https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/716/942https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/716/942http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/716/942GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/716/942/galaxies (Galaxy properties and derived parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/716/942/galaxies?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/716/942/galaxies?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/716/942/galaxies?GETtext/xml+votable180.050000true56.702141768.09610560.0055555555555555566/2121 2282 2320 2372 2374 3506 4149 4447 4511 5142 5202 5288 5463 5492 5545 5572 5581 5590 5629 5634 5715 5751 5975 6103 6649 7241 7287 7374 7602 7606 7743 8085 9277 9437 10454 10475 10817 10841 10856 10924 10925 10977 11027 11227 11434 11448 11460 11639 11681 12047 12619 13401 13489 13522 16441 18398 20270 21026 22751 24912 24957 25135 25790 26303 26317 26323 26330 26331 26338 26343 26361 26365 26432 26472 27030 27255 27512 27514 27515 27518 27728 27731 27734 27738 27739 27763 27765 27766 27767 27774 27861 27863 27917 27918 27937 27942 27945 27947 27955 28035 28037 28039 28045 28046 28123 28172 28200 28495 28496 28498 28517 28521 28524 28529 28538 28608 28653 33193 33228 33268 33920 33935 33958 34273 34343 34404 34495 35536 35993 38390 38655 42016 43262 43339 43881 45746 45748 464602.483060040379131e-20 5.517906024225661e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/716/942?format=asciiOpticalInfrareddefaultJ/ApJ/716/942/galaxiesGalaxy properties and derived parametersrecnoRecord number assigned by the VizieR team.
