cds-question@unistra.frgalaxiescatalogsradial-velocitygalaxy-classification-systemsWe use the Marcario Low Resolution Spectrograph (LRS) at the Hobby-Eberly- Telescope (HET) to study the kinematics of pseudobulges and classical bulges in the nearby universe. We present major-axis rotational velocities, velocity dispersions, and h3 and h4 moments derived from high-resolution (39km/s) spectra for 45 S0 to Sc galaxies; for 27 of the galaxies we also present minor axis data. We combine our kinematics with bulge-to-disk decompositions. We demonstrate for the first time that purely kinematic diagnostics of the bulge dichotomy agree systematically with those based on Sersic index. Low Sersic index bulges have both increased rotational support (higher v/sigma values) and on average lower central velocity dispersions. Further- more, we confirm that the same correlation also holds when visual morphologies are used to diagnose bulge type. The previously noted trend of photometrically flattened bulges to have shallower velocity dispersion profiles turns to be significant and systematic if the Sersic index is used to distinguish between pseudobulges and classical bulges. The anti-correlation between h3 and v/sigma observed in elliptical galaxies is also observed in intermediate type galaxies, irrespective of bulge type. Finally, we present evidence for formerly undetected counter rotation in the two systems NGC 3945 and NGC 4736.2012ApJ...754...67Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/754/67CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/754/67https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/754/67http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/754/67https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/754/67https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/754/67http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/754/67GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/754/67/table1 (Galaxy sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/754/67/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/754/67/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/754/67/table1?GETtext/xml+votable180.050000true40.099583339.06286110.0055555555555555566/2374 4149 4989 5182 5572 5629 5631 5634 5982 6103 7225 7241 7560 7606 7704 10841 10856 12619 13489 13522 19611 25599 26072 26271 26309 26365 26472 27030 27255 27512 27514 27515 27714 27766 27937 27945 28015 28033 28045 28167 28172 28495 28498 28517 28538https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/754/67?format=asciiOpticaldefaultJ/ApJ/754/67/table1Galaxy samplerecnoRecord number assigned by the VizieR team.
