cds-question@unistra.frgravitational-lensingquasarsWe present the results of an imaging observation campaign conducted with the Subaru Telescope adaptive optics system (IRCS+AO188) on 28 gravitationally lensed quasars and candidates (23 doubles, 1 quad, 1 possible triple, and 3 candidates) from the SDSS Quasar Lens Search. We develop a novel modelling technique that fits analytical and hybrid point spread functions (PSFs), while simultaneously measuring the relative astrometry, photometry, as well as the lens galaxy morphology. We account for systematics by simulating the observed systems using separately observed PSF stars. The measured relative astrometry is comparable with that typically achieved with the Hubble Space Telescope, even after marginalizing over the PSF uncertainty. We model for the first time the quasar host galaxies in five systems, without a priori knowledge of the PSF, and show that their luminosities follow the known correlation with the mass of the supermassive black hole. For each system, we obtain mass models far more accurate than those previously published from low-resolution data, and we show that in our sample of lensing galaxies the observed light profile is more elliptical than the mass, for ellipticity >~0.25. We also identify eight doubles for which the sources of external and internal shear are more reliably separated, and should therefore be prioritized in monitoring campaigns aimed at measuring time delays in order to infer the Hubble constant.2016MNRAS.458....2Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/458/2CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/458/2https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/458/2http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/458/2https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/458/2https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/458/2http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/458/2GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/458/2/table3a (*Information on lens systems)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/458/2/table3a?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/458/2/table3a?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/458/2/table3a?GETtext/xml+votable180.050000true115.969208324.96211110.005555555555555556Cone search capability for table J/MNRAS/458/2/table3 (Relative astrometry and photometry of the lens systems)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/458/2/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/458/2/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/458/2/table3?GETtext/xml+votable180.050000true115.969208324.96211110.005555555555555556Cone search capability for table J/MNRAS/458/2/tablea1 (TT and PSF stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/458/2/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/458/2/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/458/2/tablea1?GETtext/xml+votable180.050000true115.98212524.96267220.0055555555555555566/4315 4414-4415 4977 5190 5754 5876 5905 5907 6166 7334 8407 8423 10334 10439 10925 11063 11804 21886 21972 22007 26460-26461 26483 26525 26618 26621 28103 28112 28260 28262 28371 28538 28628 31690https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/458/2?format=asciidefaultJ/MNRAS/458/2/table1Summary of observationsrecnoRecord number assigned by the VizieR team.
