cds-question@unistra.frquasarsinfrared-astronomyspectroscopyvisible-astronomysloan-photometryredshiftedSingle-epoch virial black hole (BH) mass estimators utilizing broad emission lines have been routinely applied to high-redshift quasars to estimate their BH masses. Depending on the redshift, different line estimators (H{alpha}, H{beta}, MgII{lambda}2798, CIV{lambda}1549) are often used with optical/near-infrared spectroscopy. Here, we use a homogeneous sample of 60 intermediate-redshift (z~1.5-2.2) Sloan Digital Sky Survey quasars with optical and near-infrared spectra covering CIV through H{alpha} to investigate the consistency between different single-epoch virial BH mass estimators.2012ApJ...753..125Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/753/125CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/260 : The SDSS-DR7 quasar catalog (Schneider+, 2010)J/MNRAS/414/500 : Spitzer/IRS ATLAS project source (Hernan-Caballero+, 2011)J/MNRAS/405/2302 : Improved redshifts for SDSS quasar spectra (Hewett+, 2010)J/ApJ/699/800 : Mass functions of active black holes (Vestergaard+, 2009)J/MNRAS/382/412 : Cat. of SDSS-DR5/2MASS spectroscopic quasars (Ofek, 2007)J/ApJ/666/806 : SED of Spitzer quasars (QUEST) (Netzer+, 2007)J/ApJ/640/579 : Near-infrared spectra of 27 SDSS quasars (Glikman+, 2006)J/AJ/131/2766 : Quasar luminosity function from SDSS-DR3 (Richards+, 2006)http://www.sdss.org/ : SDSS home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/753/125https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/753/125http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/753/125https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/753/125https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/753/125http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/753/125GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/753/125/spectro (Spectral measurements of the SDSS-DR7Q sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/753/125/spectro?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/753/125/spectro?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/753/125/spectro?GETtext/xml+votable180.050000true7.4501667-9.94427780.0055555555555555566/4117 4387 4407 4656 4850 4993 5010 5520 5735 6049 6240 7353 8450 8553 8903 9918 10214 10313 10330 10963 11453 11845 17237 17241 17816 18293 18388 18389 18523 19094 19405 21847 22014 22711 23057 25976 26071 26097 26277 26336 26348 26359 26369 26985 27007 27254 27365 27480 27512 27575 27605 28376 28570 30034 30039 31318 31333 31463 490788.650015785639275e-20 2.821731604724377e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/753/125?format=asciiOpticalInfrareddefaultJ/ApJ/753/125/spectroSpectral measurements of the SDSS-DR7Q samplePlateSDSS platemeta.noteintNameQSO name (HHMM+DDMM; J2000)meta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
