cds-question@unistra.frgalaxiesvisible-astronomyspectroscopyWe here distinguish two counter-rotating stellar components in NGC 4191 and characterize their physical properties such as kinematics, size, morphology, age, metallicity. We obtained integral field spectroscopic observations with VIRUS-W and used a spectroscopic decomposition technique to separate the contribution of two stellar components to the observed galaxy spectrum. We also performed a photometric decomposition, modeling the galaxy with a Sersic bulge and two exponential disks of different scale length, with the aim of associating these structural components with the kinematic components. We then measured the equivalent width of the absorption line indices on the best-fit models that represent the kinematic components and compared our measurements to the predictions of stellar population models that also account for the variable abundance ratio of {alpha} elements.2015A&A...581A..65Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/581/A65CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/581/A65https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/581/A65http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/581/A65https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/581/A65https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/581/A65http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/581/A65GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/581/A65/list (Information on fits datacube)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/581/A65/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/581/A65/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/581/A65/list?GETtext/xml+votable180.050000true183.459127.199740.0055555555555555566/27722https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/581/A65?format=asciiOpticaldefaultJ/A+A/581/A65/listInformation on fits datacuberecnoRecord number assigned by the VizieR team.
