cds-question@unistra.frgravitational-lensinggalaxiesredshiftedgalaxy-kinematicsvisible-astronomyBy comparing the dynamical and lensing masses of early-type lens galaxies, one can constrain both the cosmological parameters and the density profiles of galaxies. We explore the constraining power on cosmological parameters and the effect of the lens mass model in this method with 161 galaxy-scale strong lensing systems, which is currently the largest sample with both high-resolution imaging and stellar dynamical data. We assume a power-law mass model for the lenses, and consider three different parametrizations for {gamma} (i.e. the slope of the total mass density profile) to include the effect of the dependence of {gamma} on redshift and surface mass density. When treating {delta} (i.e. the slope of the luminosity density profile) as a universal parameter for all lens galaxies, we find the limits on the cosmological parameter {Omega}_m_ are quite weak and biased, and also heavily dependent on the lens mass model in the scenarios of parametrizing {gamma} with three different forms. When treating {delta} as an observable for each lens, the unbiased estimate of {Omega}_m_ can be obtained only in the scenario of including the dependence of {gamma} on both the redshift and the surface mass density, that is {Omega}_m_=0.381^+0.185^_-0.154_ at 68 per cent confidence level in the framework of a flat {Lambda}CDM model. We conclude that the significant dependencies of {gamma} on both the redshift and the surface mass density, as well as the intrinsic scatter of {delta} among the lenses, need to be properly taken into account in this method.2019MNRAS.488.3745Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/488/3745CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/777/97 : SL2S galaxy-scale lens sample.
