cds-question@unistra.fractive-galactic-nucleiinfrared-photometryvisible-astronomyWide-band photometryultraviolet-photometryx-ray-sourcesWe present optical continuum lags for two Seyfert 1 galaxies, MCG+08-11-011 and NGC 2617, using monitoring data from a reverberation mapping campaign carried out in 2014. Our light curves span the ugriz filters over four months, with median cadences of 1.0 and 0.6 days for MCG+08-11-011 and NGC 2617, respectively, combined with roughly daily X-ray and near-UV data from Swift for NGC 2617. We find lags consistent with geometrically thin accretion-disk models that predict a lag-wavelength relation of {tau}{propto}{lambda}^4/3^. However, the observed lags are larger than predictions based on standard thin-disk theory by factors of 3.3 for MCG+08-11-011 and 2.3 for NGC 2617. These differences can be explained if the mass accretion rates are larger than inferred from the optical luminosity by a factor of 4.3 in MCG+08-11-011 and a factor of 1.3 in NGC 2617, although uncertainty in the SMBH masses determines the significance of this result. While the X-ray variability in NGC 2617 precedes the UV/optical variability, the long (2.6 day) lag is problematic for coronal reprocessing models.2018ApJ...854..107Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/854/107CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)J/ApJS/95/1 : Atlas of Quasar Energy Distributions (Elvis+ 1994)J/ApJ/613/682 : AGN central masses & broad-line region sizes (Peterson+, 2004)J/ApJ/622/129 : Lag-luminosity relationship in AGN (Sergeev+, 2005)J/ApJ/633/638 : Variable quasar sample from SDSS (Wilhite+, 2005)J/ApJ/788/48 : X-ray through NIR photometry of NGC 2617 (Shappee+, 2014)J/ApJ/788/159 : 17 Seyfert 1 galaxies light curves (Koshida+, 2014)J/ApJ/806/128 : Space telescope RM project.
