cds-question@unistra.frgalaxiescatalogsgalaxy-classification-systemsLine-of-sight velocities of gas and stars can constrain dark matter (DM) within rotationally supported galaxies if they trace circular orbits extensively. Photometric asymmetries may signify non-circular motions, requiring spectra with dense spatial coverage. Our integral-field spectroscopy of 178 galaxies spanned the mass range of the Sydney-AAO Multi-object integral field spectrograph (SAMI) Galaxy Survey. We derived circular speed curves (CSCs) of gas and stars from non-parametric fits out to r~2re. For 12/14 with measured HI profiles, ionized gas and HI maximum velocities agreed. We fitted mass-follows-light models to 163 galaxies by approximating the radial light profile as nested, very flattened mass homeoids viewed as a Sersic form. Fitting broad-band spectral energy distributions to Sloan Digital Sky Survey images gave median stellar mass/light 1.7 assuming a Kroupa initial mass function (IMF) versus 2.6 dynamically. Two-thirds of the dynamical mass/light measures were consistent with star+remnant IMFs. One-fifth required upscaled starlight to fit, hence comparable mass of unobserved baryons and/or DM distributed like starlight across the SAMI aperture that came to dominate motions as the starlight CSCs declined rapidly. The rest had mass distributed differently from light. Subtracting fits of Sersic radial profiles to 13 VIKING Z-band images revealed residual weak bars. Near the bar major axis, we assessed m=2 streaming velocities, and found deviations usually <30km/s from the CSC; three showed no deviation. Thus, asymmetries rarely influenced the CSC despite colocated shock-indicating, emission-line flux ratios in more than 2/3 of our sample.2016MNRAS.456.1299Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/456/1299CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/446/1567 : SAMI Galaxy Survey: EDR (Allen+, 2015)J/MNRAS/454/2050 : SAMI Pilot Survey (Fogarty+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/456/1299https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/456/1299http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/456/1299https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/456/1299https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/456/1299http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/456/1299GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/456/1299/table1 (Diskfit results for most of the SGS GAMA-Survey sub-sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/456/1299/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/456/1299/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/456/1299/table1?GETtext/xml+votable180.050000true182.0164833330.6976019440.005555555555555556Cone search capability for table J/MNRAS/456/1299/table2 (Diskfit results for the SGS cluster subsample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/456/1299/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/456/1299/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/456/1299/table2?GETtext/xml+votable180.050000true18.3633750.15247220.005555555555555556Cone search capability for table J/MNRAS/456/1299/table3 (Diskfit results for some plausible weak bars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/456/1299/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/456/1299/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/456/1299/table3?GETtext/xml+votable180.050000true222.5155105560.09749250.0055555555555555565/1024 5463 6484 6489 6571 6/4102 4104 4106 4112 4128 17237 18009 18011 18605 18607 18618 18949 18960 21845-21847 21873 21875-21878 25590-25591 25596-25597 25915 25931 25940 25942 25952-25954 25962-25963 25965-25967 26004 26049-26051 26054 26057 26254 26275-26278 26281 26288-26289 26291 26951 26961-26963 26965 26968-26969 26971 27279 27301 27303 27311-27312 27314-27315 27321 27649 27652 27656https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/456/1299?format=asciiOpticaldefaultJ/MNRAS/456/1299/table1Diskfit results for most of the SGS GAMA-Survey sub-samplerecnoRecord number assigned by the VizieR team.
