cds-question@unistra.frgravitational-lensingredshiftedgalaxy-clustershst-photometryWe present a strong lensing (SL) mass model of A1689 which resolves substructures an estimated 25kpc across within the central ~400kpc diameter. We achieve this resolution by perfectly reproducing the observed (strongly lensed) input positions of 168 multiple images of 55 knots residing within 135 images of 42 galaxies. Our model makes no assumptions about light tracing mass, yet we reproduce the brightest visible structures with some slight deviations. A1689 remains one of the strongest known lenses on the sky, with an Einstein radius of R_E_=47.0+/-1.2" (143^+3^_-4_kpc) for a lensed source at z_s_=2. We find that a single Navarro-Frenk-White (NFW) or Sersic profile yields a good fit simultaneously (with only slight tension) to both our SL mass model and published weak lensing (WL) measurements at larger radius (out to the virial radius). Our SL model prefers slightly higher concentrations than previous SL models, bringing our SL+WL constraints in line with other recent derivations. Our results support those of previous studies which find A1689 has either an anomalously large concentration or significant extra mass along the line of sight (perhaps in part due to triaxiality).2010ApJ...723.1678Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/723/1678CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)J/MNRAS/384/1611 : Submm observations in gravitational lenses (Knudsen+, 2008)J/ApJ/668/643 : Multiply imaged gravitational lens systems (Limousin+, 2007)J/ApJ/665/921 : Redshift survey in the field of A1689 (Frye+, 2007)J/MNRAS/372/1425 : Gravitational lensing analysis of A1689 (Halkola+, 2006)J/ApJ/621/53 : Multiple arc systems in A1689 (Broadhurst+, 2005)J/ApJ/627/32 : Gravitationally lensed arcs in the HST WFPC2 archive (Sand+,J/MNRAS/335/10 : H{alpha} survey of Abell 1689 (Balogh+, 2002)J/A+A/382/60 : BVR photometry in Abell 1689 (Duc+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/723/1678https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/723/1678http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/723/1678https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/723/1678https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/723/1678http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/723/1678GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/723/1678/table4 (Spectroscopic redshifts of galaxies within the ACS field of view of A1689 used for our photometric redshift tests)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/723/1678/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/723/1678/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/723/1678/table4?GETtext/xml+votable180.050000true197.88585833-1.323033330.005555555555555556Cone search capability for table J/ApJ/723/1678/table5 (Multiple images produced by A1689 of 42 galaxies (corrected version, see table A1 in arXiv:1402.4170))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/723/1678/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/723/1678/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/723/1678/table5?GETtext/xml+votable180.050000true197.86021667-1.332430560.005555555555555556Cone search capability for table J/ApJ/723/1678/table6 (Extra knots identified in the multiple images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/723/1678/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/723/1678/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/723/1678/table6?GETtext/xml+votable180.050000true197.88380833-1.349550.0055555555555555566/26189https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/723/1678?format=asciiOpticaldefaultJ/ApJ/723/1678/table4Spectroscopic redshifts of galaxies within the ACS field of view of A1689 used for our photometric redshift testsrecnoRecord number assigned by the VizieR team.
