cds-question@unistra.frquasarsinfrared-astronomyspectroscopysurveysline-intensitiesredshiftedWe present spectroscopic measurements for 226 sources from the Gemini Near Infrared Spectrograph-Distant Quasar Survey (GNIRS-DQS). Being the largest uniform, homogeneous survey of its kind, it represents a flux-limited sample (m_i_<~19.0mag, H<~16.5mag) of Sloan Digital Sky Survey (SDSS) quasars at 1.5<~z<~3.5 with a monochromatic luminosity ({lambda}L_{lambda}_) at 5100{AA} in the range of 10^44^-10^46^erg/s. A combination of the GNIRS and SDSS spectra covers principal quasar diagnostic features, chiefly the CIV{lambda}1549, MgII{lambda}{lambda}2798,2803, H{beta}{lambda}4861, and [OIII]{lambda}{lambda}4959,5007 emission lines, in each source. The spectral inventory will be utilized primarily to develop prescriptions for obtaining more accurate and precise redshifts, black hole masses, and accretion rates for all quasars. Additionally, the measurements will facilitate an understanding of the dependence of rest-frame ultraviolet-optical spectral properties of quasars on redshift, luminosity, and Eddington ratio, and test whether the physical properties of the quasar central engine evolve over cosmic time.2021ApJS..252...15Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/252/15CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/279 : SDSS quasar catalog, twelfth data release (Paris+, 2017)VII/286 : SDSS quasar catalog, fourteenth data release (Paris+, 2018)VII/289 : SDSS quasar catalog, sixteenth data release (DR16Q) (Lyke+, 2020)J/A+A/333/231 : O-M stars model atmospheres (Bessell+ 1998)J/AJ/131/2766 : Quasar luminosity function from SDSS-DR3 (Richards+, 2006)J/MNRAS/405/2302 : Improved redshifts for SDSS quasar spectra (Hewett+, 2010)J/ApJ/708/137 : Broad-line AGNs in zCOSMOS survey (Merloni+, 2010)J/ApJS/194/45 : QSO properties from SDSS-DR7 (Shen+, 2011)J/ApJ/753/125 : NIR spectroscopy follow-up of 60 SDSS-DR7 QSOs (Shen+, 2012)J/ApJ/813/82 : z<0.06 broad-line AGN emission-line measures (Reines+, 2015)J/ApJ/817/55 : NIR spectroscopy of 1.5<z<3.5 broad-band QSOs (Shen, 2016)J/ApJ/831/7 : SDSS-RM project: peak velocities of QSOs (Shen+, 2016)J/MNRAS/465/2120 : Correcting CIV-based virial BH masses (Coatman+, 2017)J/ApJ/871/258 : ELQS in SDSS.
