cds-question@unistra.frgravitational-lensingredshiftedWe have used strong gravitational lensing to perform a study of the mass distribution of the galaxy cluster MACS J0035.4-2015 by modeling its total mass distribution, and at the same time, constrain the geometry of the Universe in various cosmological models. The combination of high-resolution imaging from the Hubble Space Telescope with ground-based spectroscopy with the Multi Unit Spectroscopic Explorer mounted at the VLT allows us to model the observed multiple image positions with ~0.3" precision. Firstly we found that MACS J0035.4-2015 can be best described by a combination of an elliptical dark matter halo as an isothermal mass profile, with the brightest cluster galaxy and cluster members, each with a spherical truncated isothermal parameterization. With these assumptions, the total mass is estimated to be ~6x10^13^M_{sun}_ within 100kpc. In order to constrain the background geometry of the Universe, we adopt four different cosmological models. All of the resulting values of the cosmological parameters in these cosmological models are statistically consistent with the flat Lambda CDM model with an estimated value of {Omega}_m. By combining the results with five other clusters from previous studies, we could reduce the uncertainties and obtain a more precise value of {Omega}_m. Our results show that cluster strong gravitational lensing is a formidable probe to be included in future cosmological surveys.2025A&A...698A.161Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/698/A161CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/698/A161https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/698/A161http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/698/A161https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/698/A161https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/698/A161http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/698/A161GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/698/A161/table2 (*MUSE redshift catalogue for MACS J0035.4-2015)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/698/A161/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/698/A161/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/698/A161/table2?GETtext/xml+votable180.050000true8.8579363-20.2578710.0055555555555555566/16787https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/698/A161?format=asciidefaultJ/A+A/698/A161/table2*MUSE redshift catalogue for MACS J0035.4-2015recnoRecord number assigned by the VizieR team.
