cds-question@unistra.frgalaxiescatalogsredshiftedWe present dynamical measurements for 586 H{alpha}-detected star-forming galaxies from the KMOS (K-band Multi-Object Spectrograph) Redshift One Spectroscopic Survey (KROSS). The sample represents typical star-forming galaxies at this redshift (z=0.6-1.0), with a median star formation rate of ~=7M_{sun}_/yr and a stellar mass range of log(M*_[M_{sun}_])~9-11. We find that the rotation velocity-stellar mass relationship (the inverse of the Tully-Fisher relationship) for our rotationally dominated sources (v_C_/{sigma}_0_>1) has a consistent slope and normalization as that observed for z=0 discs. In contrast, the specific angular momentum (j*; angular momentum divided by stellar mass) is ~=0.2-0.3dex lower on average compared to z=0 discs. The specific angular momentum scales as j_s_{prop.to}M*^0.6+/-0.2^, consistent with that expected for dark matter (i.e. j_DM_{prop.to} M_DM_^2/3^). We find that z~=0.9 star-forming galaxies have decreasing specific angular momentum with increasing Sersic index. Visually, the sources with the highest specific angular momentum, for a given mass, have the most disc-dominated morphologies. This implies that an angular momentum-mass-morphology relationship, similar to that observed in local massive galaxies, is already in place by z~=1.2017MNRAS.467.1965Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/467/1965CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/203/24 : Structural parameters of CANDELS galaxies (van der Wel+, 2012)http://astro.dur.ac.uk/KROSS : KROSS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/467/1965https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/467/1965http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/467/1965https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/467/1965https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/467/1965http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/467/1965GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/467/1965/krossv2 (KROSS V2 catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/467/1965/krossv2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/467/1965/krossv2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/467/1965/krossv2?GETtext/xml+votable180.050000true149.918572.113261940.0055555555555555565/4759 6/17690 19035 19057 19060 27256 27258 35935 359577.952274030004205e-20 1.0188844282367877e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/467/1965?format=asciidefaultJ/MNRAS/467/1965/krossv2KROSS V2 catalogl_JS[-] limit flag on JSmeta.code.errorcharrecnoRecord number assigned by the VizieR team.
