cds-question@unistra.frquasarsredshiftedsurveysvisible-astronomyWe present accretion disk structure measurements from continuum lags in the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) project. Lags are measured using the JAVELIN software from the first-year SDSS-RM g and i photometry, resulting in well-defined lags for 95 quasars, 33 of which have lag S/N>2{sigma}. We also estimate lags using the ICCF software and find consistent results, though with larger uncertainties. Accretion disk structure is fit using a Markov chain Monte Carlo approach, parameterizing the measured continuum lags as a function of disk size normalization, wavelength, black hole mass, and luminosity. In contrast with previous observations, our best-fit disk sizes and color profiles are consistent (within 1.5{sigma}) with the Shakura & Sunyaev (1973A&A....24..337S) analytic solution. We also find that more massive quasars have larger accretion disks, similarly consistent with the analytic accretion disk model. The data are inconclusive on a correlation between disk size and continuum luminosity, with results that are consistent with both no correlation and the Shakura & Sunyaev expectation. The continuum lag fits have a large excess dispersion, indicating that our measured lag errors are underestimated and/or our best-fit model may be missing the effects of orientation, spin, and/or radiative efficiency. We demonstrate that fitting disk parameters using only the highest-S/N lag measurements biases best-fit disk sizes to be larger than the disk sizes recovered using a Bayesian approach on the full sample of well-defined lags.2019ApJ...880..126Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/880/126CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/286 : SDSS quasar catalog, fourteenth data release (Paris+, 2018)J/ApJ/622/129 : Lag-luminosity relationship in AGN (Sergeev+, 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/733/60 : Accretion rate of AGNs from COSMOS surveys (Trump+, 2011)J/ApJ/788/48 : X-ray through NIR photometry of NGC 2617 (Shappee+, 2014)J/ApJ/806/22 : SEAMBHs IV.
