cds-question@unistra.frline-intensitiesspectroscopyredshiftedquasarsWe report on a systematic investigation of the H{beta} and FeII emission lines in a sample of 568 quasars within z<0.8 selected from the Sloan Digital Sky Survey quasar catalog (DR5, Cat. VII/252). The conventional broad H{beta} emission line can be decomposed into two components: one with intermediate velocity width and another with very broad width. The velocity shift and equivalent width of the intermediate-width component do not correlate with those of the very broad component of H{beta}, but its velocity shift and width do resemble FeII. Moreover, the width of the very broad component is roughly 2.5 times that of the intermediate-width component. These characteristics strongly suggest the existence of an intermediate-line region, whose kinematics seem to be dominated by infall, located at the outer portion of the broad-line region.2008ApJ...683L.115Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/683/L115CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/260 : The SDSS-DR7 quasar catalog (Schneider+, 2010)J/ApJ/674/668 : SDSS J102839.11+450009.4 Fe II emission lines (Wang+, 2008)J/ApJ/687/78 : FeII emission in quasars (Hu+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/683/L115https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/683/L115http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/683/L115https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/683/L115https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/683/L115http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/683/L115GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/683/L115/table1 (Line measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/683/L115/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/683/L115/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/683/L115/table1?GETtext/xml+votable180.050000true1.440041715.64272220.0055555555555555566/0 2 4097 4101 4107 4139 4143 4163 4186 4193 4194 4204 4226 4229 4256 4368 4606 4738 4745 4749 4790 4803 4812 4817 4824 4826 4845 4852 4886 4902 4933 4940 4961 4966 4974 4992 4996 5008 5015 5043 5057 5068 5076 5111 5117 5210 5221 5247 5271 5295 5304 5305 5354 5359 5365 5369 5372 5375 5391 5397 5409 5416 5451 5453 5475 5481 5489 5504 5505 5515 5527 5531 5547 5549 5584 5607 5613 5619 5632 5642 5646 5685 5687 5688 5691 5715 5728 5733 5746 5748 5756 5757 5767 5769 5776 5798 5820 5821 5829 5861 5876 5881 5891 5894 5898 5944 5947 5964 5975 5988 6030 6045 6057 6061 6074 6106 6112 6138 6165 6167 6229 6235 6241 6244 6267 6270 6358 6359 6420 6438 6466 6468 6471 6473 6476 6488 6489 6493 6533 6544 6551 6555 6563 6571 6574 6590 6593 6596 6600 6605 6622 6635 7169 7176 7181 7182 7188 7193 7199 7208 7214 7226 7231 7237 7239 7242 7249 7275 7288 7306 7330 7331 7369 7377 7435 7445 7446 7452 7460 7505 7516 7518 7526 7529 7530 7684 8235 8395 8669 8700 8702 8913 9045 9072 9074 9146 9149 9154 9187 9192 9196 9200 9213 9222 9232 9263 9277 9393 9412 9422 9436 9439 9441 9456 9461 9471 9483 9608 9643 9743 9747 9753 9769 9790 9817 9825 9900 9923 9948 9954 9959 9968 9980 9989 9998 10017 10019 10024 10094 10104 10152 10182 10188 10190 10191 10194 10338 10385 10428 10436 10495 10503 10517 10523 10527 10543 10578 10584 10587 10604 10623 10624 10630 10637 10647 10653 10674 10694 10707 10715 10717 10724 10732 10734 10751 10848 10873 10881 10889 10899 10939 10969 10981 11021 11050 11073 11076 11096 11114 11125 11226 11233 11245 11263 11270 11276 11281 11283 11315 11335 11351 11383 11385 11394 11415 11437 11439 11456 11462 11473 11475 11482 11502 11593 11596 11781 11782 11787 11795 11824 11826 11845 11848 11872 11925 11930 11943 11954 16894 17214 17230 17231 17233 17260 17302 17487 17494 17497 17522 17558 17560 17572 17573 17574 17673 17750 17751 17754 17756 17771 17772 17819 17822 17829 17834 18005 18020 18023 18027 18386 18404 18407 18409 18515 18518 18535 18536 18581 18591 18628 18686 18751 18770 18771 18776 18786 18834 18837 18945 18951 18954 19037 19099 19101 19109 19116 19136 19407 19416 19417 19675 19741 19991 19997 21854 21886 21983 21991 21997 22003 22762 23057 23059 23062 23076 23185 23189 23190 23198 23201 23209 23211 23216 25586 25851 25935 25977 25998 26008 26011 26013 26014 26024 26082 26100 26175 26186 26204 26228 26233 26246 26352 26356 26381 26389 26396 26400 26406 26552 26555 26606 26952 27002 27006 27023 27026 27032 27033 27049 27059 27074 27082 27084 27090 27096 27110 27235 27252 27282 27291 27324 27326 27331 27343 27353 27360 27391 27475 27485 27494 27501 27513 27552 27565 27593 27604 27618 27661 27686 27725 27732 27740 27782 27784 27799 27813 27815 27824 27825 27826 27828 27834 27848 27850 27917 27924 27945 27952 28170 28180 28192 28197 28575 28607 28643 28646 28654 28660 31291 31315 31341 31372 31396 31434 31456 31623 32403 32409 32441 32459 32483 32682 32683 36703 36763 36783 36788 36789 36802 36803 45053 49009https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/683/L115?format=asciiOpticaldefaultJ/ApJ/683/L115/table1Line measurementsSloanDisplay the SDSS data for this quasarmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
