cds-question@unistra.frgiant-starsradial-velocityinfrared-photometryvisible-astronomyphotometrygalaxiesWe present kinematic and metallicity profiles for the M 31 dwarf elliptical (dE) satellite galaxies NGC 147 and NGC 185. The profiles represent the most extensive spectroscopic radial coverage for any dE galaxy, extending to a projected distance of 8 half-light radii (8r_eff_~14'). We achieve this coverage via Keck/DEIMOS multislit spectroscopic observations of 520 and 442 member red giant branch stars in NGC 147 and NGC 185, respectively. In contrast to previous studies, we find that both dEs have significant internal rotation. We measure a maximum rotational velocity of 17+/-2km/s for NGC 147 and 15+/-5km/s for NGC 185. The velocity dispersions decrease gently with radius with average dispersions of 16+/-1km/s and 24+/-1km/s for NGC 147 and NGC 185, respectively. The average metallicities for NGC 147 and NGC 185 are [Fe/H]=-1.1+/-0.1 and [Fe/H]=-1.3+/-0.1, respectively; both dEs have internal metallicity dispersions of 0.5dex, but show no evidence for a radial metallicity gradient.2010ApJ...711..361Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/711/361CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/cfht : Log of CFHT Exposures (CADC, 1979-)J/A+A/532/A78 : Long-period variables in NGC 147 and NGC 185 (Lorenz+, 2011)J/A+A/445/69 : JHK' photometry of C stars in NGC 147 (Sohn+, 2006)J/A+A/437/61 : Near-IR photometry of AGB stars in NGC 185 (Kang+, 2005)J/A+A/418/33 : RI photometry of C stars in NGC 147 (Battinelli+, 2004)J/A+A/417/479 : RI photometry of NGC 185 carbon stars (Battinelli+, 2004)J/A+A/403/93 : Photometry of AGB stars in NGC 185 and NGC 147 (Nowotny+, 2003)J/AJ/113/1001 : Stellar photometry in NGC 147 (Han+ 1997)J/AJ/106/964 : BVRI photometry of NGC 185 stellar population (Lee+, 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/711/361https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/711/361http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/711/361https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/711/361https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/711/361http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/711/361GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/711/361/veloc (Combined table from original tables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/711/361/veloc?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/711/361/veloc?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/711/361/veloc?GETtext/xml+votable180.050000true8.2648.3879720.0055555555555555566/2774 2777 27802.367228618189496e-19 2.6706780932288093e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/711/361?format=asciiInfraredOpticaldefaultJ/ApJ/711/361/velocCombined table from original tablesrecnoRecord number assigned by the VizieR team.
