cds-question@unistra.frgalaxy-clustersredshiftedWe present a reconstruction of the mass distribution of galaxy cluster Abell 1689 at z=0.18 using detected strong lensing features from deep ACS observations and extensive ground based spectroscopy. Earlier analyses have reported up to 32 multiply imaged systems in this cluster, of which only 3 were spectroscopically confirmed. In this work, we present a parametric strong lensing mass reconstruction using 34 multiply imaged systems of which 24 have newly determined spectroscopic redshifts, which is a major step forward in building a robust mass model. In turn, the new spectroscopic data allows a more secure identification of multiply imaged systems.2007ApJ...668..643Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/668/643CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/668/643https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/668/643http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/668/643https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/668/643https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/668/643http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/668/643GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/668/643/table1 (Multiply imaged systems considered in this work)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/668/643/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/668/643/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/668/643/table1?GETtext/xml+votable180.050000true197.86019583-1.332411110.0055555555555555566/26189https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/668/643?format=asciiOpticaldefaultJ/ApJ/668/643/table1Multiply imaged systems considered in this workrecnoRecord number assigned by the VizieR team.
