The ground- based photometric monitoring was conducted on a daily basis with the robotic 46cm telescope of the Wise observatory located in Israel. Specially designed narrowband filters were used to observe the central engine of the active galactic nucleus (AGN), avoiding line contamination from the broad-line region (BLR). We aim to measure inter- band continuum time lags across the optical range and determine the size-wavelength relation for this system. PG 2130+099 displays correlated variability across the optical range, and we successfully detect significant time lags of up to 3 days between the multiband light curves. While a continuum reprocessing model can fit the data reasonably well, our derived disk sizes are a factor of 2-6 larger than the theoretical disk sizes predicted from the AGN luminosity estimate of PG 2130+099. This result is in agreement with previous studies of AGN/quasars and suggests that the standard Shakura- Sunyaev disk theory has limitations in describing AGN accretion disks.2022A&A...659A..13Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/659/A13CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/890/71 : PG2130+099 5100{AA} continuum + emission lines LCs (Hu+, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/659/A13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/659/A13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/659/A13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/659/A13https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/659/A13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/659/A13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/659/A13/table1Normalized NB4250 light curve (PSF photometry)recnoRecord number assigned by the VizieR team.
