cds-question@unistra.frquasarsvisible-astronomyspectroscopyredshiftedinfrared-photometryphotometrysurveysWe present reverberation-mapping (RM) lags and black hole mass measurements using the CIV{lambda}1549 broad emission line from a sample of 348 quasars monitored as a part of the Sloan Digital Sky Survey RM Project. Our data span four years of spectroscopic and photometric monitoring for a total baseline of 1300 days, allowing us to measure lags up to ~750days in the observed frame (this corresponds to a rest-frame lag of ~300days in a quasar at z=1.5 and ~190days at z=3). We report significant time delays between the continuum and the CIV{lambda}1549 emission line in 48 quasars, with an estimated false-positive detection rate of 10%. Our analysis of marginal lag measurements indicates that there are on the order of ~100 additional lags that should be recoverable by adding more years of data from the program. We use our measurements to calculate black hole masses and fit an updated CIV radius-luminosity relationship. Our results significantly increase the sample of quasars with CIV RM results, with the quasars spanning two orders of magnitude in luminosity toward the high-luminosity end of the CIV radius-luminosity relation. In addition, these quasars are located at some of the highest redshifts (z~1.4-2.8) of quasars with black hole masses measured with RM.2019ApJ...887...38Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/887/38CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/147 : The SDSS Photometric Catalogue, Release 12 (Alam+, 2015)VII/289 : SDSS quasar catalog, sixteenth data release (DR16Q) (Lyke+, 2020)J/ApJ/613/682 : AGN central masses & broad-line region sizes (Peterson+, 2004)J/ApJ/632/799 : NGC4395 light curves (Peterson+, 2005)J/ApJS/166/470 : SDSS-Spitzer type I QSOs IR photometry (Richards+, 2006)J/ApJ/698/895 : Variations in QSOs optical flux (Kelly+, 2009)J/ApJ/716/993 : LAMP: reverberation mapping of H and He lines (Bentz+, 2010)J/ApJS/194/45 : QSO properties from SDSS-DR7 (Shen+, 2011)J/ApJ/755/60 : Reverberation mapping for 5 Seyfert 1 galaxies (Grier+, 2012)J/other/Sci/338.1445 : Relativistic jets from BH systems (Nemmen+, 2012)J/ApJ/746/169 : Luminosity function of broad-line quasars (Shen+, 2012)J/ApJ/777/168 : CIV and SiIV BAL troughs in SDSS (Filiz+, 2013)J/ApJ/779/109 : Long-term monitoring of NGC 5548 (Peterson+, 2013)J/ApJ/782/45 : SEAMBHs.
