cds-question@unistra.frgalaxiesspectroscopyredshiftedgalaxy-classification-systemsinfrared-photometryWe present adaptive optics assisted integral field spectroscopy of 34 star-forming galaxies at z=0.8-3.3 selected from the HiZELS narrow-band survey. We measure the kinematics of the ionized interstellar medium on ~1kpc scales, and show that the galaxies are turbulent, with a median ratio of rotational to dispersion support of V/{sigma}=0.82+/-0.13. We combine the dynamics with high-resolution rest-frame optical imaging and extract emission-line rotation curves. We show that high-redshift star-forming galaxies follow a similar power-law trend in specific angular momentum with stellar mass to that of local late-type galaxies. We exploit the high resolution of our data and examine the radial distribution of angular momentum within each galaxy by constructing total angular momentum profiles. Although the stellar mass of a typical star-forming galaxy is expected to grow by a factor ~8 in the ~5Gyr between z~3.3 and z~0.8, we show that the internal distribution of angular momentum becomes less centrally concentrated in this period; that is, the angular momentum grows outwards. To interpret our observations, we exploit the EAGLE simulation and trace the angular momentum evolution of star-forming galaxies from z~3 to z~0, identifying a similar trend of decreasing angular momentum concentration. This change is attributed to a combination of gas accretion in the outer disc, and feedback that preferentially arises from the central regions of the galaxy. We discuss how the combination of the growing bulge and angular momentum stabilizes the disc and gives rise to the Hubble sequence.2019MNRAS.486..175Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/486/175CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/486/175https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/486/175http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/486/175https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/486/175https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/486/175http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/486/175GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/486/175/tablea1 (Integrated galaxy properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/486/175/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/486/175/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/486/175/tablea1?GETtext/xml+votable180.050000true335.5960.79250.0055555555555555566/17677 17679 17688 17690 19036-19038 27256 27258-272591.143914381504295e-19 1.2934455535160846e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/486/175?format=asciiOpticalInfrareddefaultJ/MNRAS/486/175/tablea1Integrated galaxy propertiesrecnoRecord number assigned by the VizieR team.
