cds-question@unistra.frgravitational-lensingccd-photometryspectrophotometryWe studied the accretion disc structure in the doubly imaged lensed quasar SDSS J1339+1310 using r-band light curves and UV-visible to near-IR spectra from the first 11 observational seasons after its discovery. The 2009-2019 light curves displayed pronounced microlensing variations on different timescales, and this microlensing signal permitted us to constrain the half-light radius of the 1930{AA} continuum-emitting region. Assuming an accretion disc with an axis inclined at 60{deg} to the line of sight, we obtained log(r_1/2_/cm)=15.4_-0.4+^+0.93%. We also estimated the central black hole mass from spectroscopic data. The width of the CIV, MgII, and H{beta} emission lines, and the continuum luminosity at 1350, 3000, and 5100{AA}, led to log(M_BH_/M_{sun}_)=8.6+/-0.4. Thus, hot gas responsible for the 1930{AA} continuum emission is likely orbiting a 4.0x10^8^M_{sun}_ black hole at an r_1/2_ of only a few tens of Schwarzschild radii.2021A&A...646A.165Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/646/A165CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/596/A77 : SDSS J1339+1310 spectra and light curves (Goicoechea+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/646/A165https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/646/A165http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/646/A165https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/646/A165https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/646/A165http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/646/A165GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap2.85864675833786e-19 3.5010283109654867e-19defaultJ/A+A/646/A165/table1*Light curves in the r band (623.7nm)recnoRecord number assigned by the VizieR team.
