cds-question@unistra.frgalaxiesspectroscopygalaxy-classification-systemsredshiftedsurveysStellar counterrotating (CR) galaxies are systems hosting two large-scale stellar components rotating in opposite directions-a main, preexisting galaxy body with an older stellar population and a younger CR stellar disk likely formed from externally accreted gas. Such systems offer a unique opportunity to study disk assembly by analyzing the stellar populations of each component. Using integral field spectroscopic data from the SDSS-IV Mapping Nearby Galaxies at Apache Point Observatory survey, we identified a sample of 120 CR disk galaxies (65 reliable and 55 probable systems) by inspecting their kinematic maps and analyzing the shape of the stellar line-of-sight velocity distribution, which was recovered nonparametrically. Of these, 74 CR galaxies have not been reported in previous studies. For one-third of our sample, we further derived the ages and metallicities of stars for both disks via a spectral decomposition technique. We show that the observed spatial bimodality-where the CR disk either is concentrated in the central region (inner counterrotation) or dominates the outer part of the galaxy (outer counterrotation)-is driven by differences in the stellar mass and angular momentum of the CR disk. The wide range of stellar metallicities observed in CR disks suggests that no single source of external material is solely responsible for the formation of counterrotation in all galaxies; instead, proposed mechanisms such as merger with gas-rich satellites, accretion from cosmic filaments, and exchange of gas between neighboring galaxies can dominate in individual cases.2025ApJS..281...19Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/281/19CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/286 : APOGEE-2 DR17 final allStar catalog (Abdurro'uf+, 2022)J/A+AS/125/229 : A standard stellar library (Lejeune+ 1997)J/A+A/424/447 : Kinematics in 17 nearby spiral galaxies (Pizzella+, 2004)J/A+A/578/A110 : Isolated gal., pairs and triplets (Argudo-Fernandez+, 2015)J/ApJS/219/8 : SFR for WISE + SDSS spectroscopic galaxies (Chang+, 2015)J/A+A/581/A65 : IFU observations of NGC 4191 (Coccato+, 2015)J/AJ/154/86 : MaNGA catalog, DR15 (Wake+, 2017)J/MNRAS/477/4711 : Stellar angular momentum for MaNGA galaxies (Graham+, 2018)J/ApJ/861/49 : ALFALFA extragalactic HI source catalog (Haynes+, 2018)J/A+A/651/L15 : Angular-momentum plane for disc gal.
