cds-question@unistra.frquasarsactive-galactic-nucleispectroscopyThe integrated line width derived from CO spectroscopy provides a powerful tool to study the internal kinematics of extragalactic objects, including quasars at high redshift, provided that the observed line width can be properly translated to more conventionally used kinematical parameters of galaxies. We show, through the construction of a Ks-band CO Tully-Fisher relation for nearby galaxies spanning a wide range in infrared luminosity, that the CO line width measured at 20% of the peak intensity, when corrected for inclination and other effects, successfully recovers the maximum rotation velocity of the disk. The line width at 50% of the peak intensity performs much more poorly, in large part because CO lines have a wide range of profiles, which are shown to vary systematically with infrared luminosity. We present a practical prescription for converting observed CO line widths into the stellar velocity dispersion of the bulge ({sigma}*) and then apply it to a sample of low-redshift (z<~0.2) and high-redshift (1.4<~z<~6.4) quasars to study their host galaxies.2007ApJ...669..821Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/669/821CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/669/821https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/669/821http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/669/821https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/669/821https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/669/821http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/669/821GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/669/821/table1 (The galaxy sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/669/821/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/669/821/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/669/821/table1?GETtext/xml+votable180.050000true138.9812544.33277780.005555555555555556Cone search capability for table J/ApJ/669/821/table2 (The quasar sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/669/821/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/669/821/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/669/821/table2?GETtext/xml+votable180.050000true13.395512.69330560.0055555555555555566/226 538 627 650 700 1682 1689 1690 1696 1714 2211 2215 2222 2259 2261 2269 2347 2360 2363 2397 2409 2432 2437 2709 2716 2722 3389 3934 4124 4718 4719 4804 4813 4993 5116 5523 5560 5610 5630 5816 5852 5999 7309 7424 7426 7606 7998 8071 8106 8266 8482 8673 8707 8712 8906 8913 8921 8922 9133 9194 9895 9998 10081 10144 10210 10283 10378 10379 10381 10394 10401 10402 10465 10578 10694 10761 10856 11029 11101 11180 11206 11290 11375 11434 11668 11800 11829 11908 12380 14886 15323 15592 16045 16120 16755 17075 17736 17754 17819 17939 18212 18387 18714 18809 18930 18932 18941 19283 19288 19433 19619 19730 19932 20000 20060 20061 20225 20254 20394 21016 22654 22721 23148 23451 23525 23887 25083 25540 25817 25965 26264 26298 26448 26451 26457 26811 27232 27537 27617 27801 27803 27806 28060 28134 28141 28150 28164 28167 28184 28188 28249 28251 28253 28272 28279 28280 28393 28449 28566 28609 29937 30008 30565 31081 31158 31303 34273 34531 36194 43925 44671https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/669/821?format=asciiOpticaldefaultJ/ApJ/669/821/table1The galaxy sampleRefReference for CO data (5)meta.ref;pos.frameintNotesAdditional notes (6)meta.notecharrecnoRecord number assigned by the VizieR team.
