cds-question@unistra.frgravitational-lensingredshiftedgalaxy-kinematicsvisible-astronomyInspired by a new compilation of strong-lensing systems, which consist of 204 points in the redshift range 0.0625<z_l_<0.958 for the lens and 0.196<z_s_<3.595 for the source, we constrain three models that generate a late cosmic acceleration: the {omega}-cold dark matter model, the Chevallier-Polarski-Linder, and the Jassal-Bagla-Padmanabhan parametrizations. Our compilation contains only those systems with early-type galaxies acting as lenses, with spectroscopically measured stellar velocity dispersions, estimated Einstein radius, and both the lens and source redshifts. We assume an axially symmetric mass distribution in the lens equation, using a correction to alleviate differences between the measured velocity dispersion ({sigma}) and the dark matter halo velocity dispersion ({sigma}_DM_) as well as other systematic errors that may affect the measurements. We have considered different subsamples to constrain the cosmological parameters of each model. Additionally, we generate a mock data of SLS to asses the impact of the chosen mass profile on the accuracy of Einstein radius estimation. Our results show that cosmological constraints are very sensitive to the selected data: Some cases show convergence problems in the estimation of cosmological parameters (e.g. systems with observed distance ratio D^obs^<0.5), others show high values for the {chi}^2^ function (e.g. systems with a lens equation D^obs^>1 or high velocity dispersion {sigma}>276km/s). However, we obtained a fiduciary sample with 143 systems, which improves the constraints on each tested cosmological model.2020MNRAS.498.6013Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/498/6013CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/498/6013https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/498/6013http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/498/6013https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/498/6013https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/498/6013http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/498/6013GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/498/6013/tablea1 (Compilation of 204 strong-lensing measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/498/6013/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/498/6013/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/498/6013/tablea1?GETtext/xml+votable180.050000true124.883072545.57912190.0055555555555555566/2165 4134 4182 4352 4615 4695 4762-4763 4853 4899 4976 5292 5297 5312 5340 5500 5530 5562 5701 5719 5743 5802 5819 5878 5951 5986 5992 6105 6133 6269 6340 6352 6393 6470 6585 6599 6607 6628 6981 7242 7305 7347 7426 8505 8510 8555 8563 8568 8649 8700 9039 9084 9102 9245 9385 9409 9778 9809 9846 9995 10020 10355 10453 10459 10528 10596 10741 10748-10749 10883 10943 10990 11041 11184 11347 11389 11424-11425 11439 11448 11499 11777 11797 11850 11948 16644 16836 17238 17321 17489 17494 17510 17665 17667 17678 17682 17685 17687 17689-17690 17692 17712 17751 17816-17817 17840 18072 18089 18114 18542 18759 18778 18798 18836 18841 18844 19007 19027 19030 19032 19037 19059 19065 19135 19401 19776 19950 20003 22581 23061 23181 23193 23216 23339 25245 25599 25839 25852 25957 25975 26012 26159 26195 26279 26331 26498 26532 26620 26951 27053 27126 27134-27135 27196 27204 27258 27308 27318 27348 27407 27518 27551 27672 27689 27726 27803 28206 28239 28278 28369 28411 28459 28515 30974 31378 31706 31743 32680 36427 36766 36796 40935 40940-40941 40943 40955 40957 45050 48389https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/498/6013?format=asciiOpticaldefaultJ/MNRAS/498/6013/tablea1Compilation of 204 strong-lensing measurementsSimbadNameSimbad column added by the CDSmeta.idcharnullablezlLens redshiftsrc.redshift;pos.heliocentricfloatrecnoRecord number assigned by the VizieR team.
