cds-question@unistra.frgalaxy-clustersgravitational-lensingWe present our lens mass model of SMACS J0723.3-7327, the first strong gravitational lens observed by the James Webb Space Telescope (JWST). We use data from the Hubble Space Telescope and Multi Unit Spectroscopic Explorer (MUSE) to build our "pre-JWST" lens model, and refine it with newly available JWST near-infrared imaging in our JWST model. To reproduce the positions of all multiple lensed images with good accuracy, the adopted mass parameterization consists of one cluster-scale component, accounting mainly for the dark matter distribution, the galaxy cluster members and an external shear component. The pre-JWST model has, as constraints, 19 multiple images from six background sources, of which four have secure spectroscopic redshift measurements from this work. The JWST model has more than twice the number of constraints, 30 additional multiple images from another eleven lensed sources. Both models can reproduce very well the multiple image positions with a rms of 0.39" and 0.51", for the pre-JWST and JWST models, respectively. The total mass estimates within a radius of 128kpc (roughly the Einstein radius) are 7.9^+0.3^_-0.2_*10^13^M_{sun}_ and 8.7^+0.2^_-0.2_*10^13^M_{sun}_, for the pre-JWST and JWST models, respectively. We predict with our mass models the redshifts of the newly detected JWST sources, which are crucial information especially for systems without spectroscopic measurements for further studies and follow-up observations. Interestingly, one family detected with JWST is found to be at a very high redshift, z>7.5 (68% confidence level) and with one image having lensing magnification of |{mu}|=9.5^+0.9^_-0.8_, making it an interesting case for future studies. The lens models, including magnification maps and redshifts estimated from the model are made publicly available, along with the full spectroscopic redshift catalogue from MUSE.2022A&A...666L...9Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/666/L9CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/666/L9https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/666/L9http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/666/L9https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/666/L9https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/666/L9http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/666/L9GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/666/L9/muse (MUSE redshift catalogue (table A1))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/666/L9/muse?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/666/L9/muse?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/666/L9/muse?GETtext/xml+votable180.050000true110.8284294-73.46025740.005555555555555556Cone search capability for table J/A+A/666/L9/list (List of fits magnification maps)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/666/L9/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/666/L9/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/666/L9/list?GETtext/xml+votable180.050000true110.82681-73.454640.0055555555555555566/37395https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/666/L9?format=asciidefaultJ/A+A/666/L9/museMUSE redshift catalogue (table A1)recnoRecord number assigned by the VizieR team.
