AbstractAbstract We present reverberation-mapping (RM) lags and black hole mass measurements using the C ivλ1549 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 ~750 days in the observed frame (this corresponds to a rest-frame lag of ~300 days in a quasar at z?=?1.5 and ~190 days at z?=?3). We report significant time delays between the continuum and the C ivλ1549 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 C iv?radius–luminosity relationship. Our results significantly increase the sample of quasars with C iv?RM results, with the quasars spanning two orders of magnitude in luminosity toward the high-luminosity end of the C iv?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. This work constitutes the first large sample of C iv?RM measurements in more than a dozen quasars, demonstrating the utility of multiobject RM campaigns.
