cds-question@unistra.frseyfert-galaxiesgalaxiesspectroscopyco-line-emissionvisible-astronomyTracing nuclear inflows and outflows in AGNs, determining the mass of gas involved in them, and their impact on the host galaxy and nuclear black hole requires 3-D imaging studies of both the ionized and molecular gas. We map the distribution and kinematics of molecular and ionized gas in a sample of active galaxies to quantify the nuclear inflows and outflows. Here, we analyze the nuclear kinematics of NGC 1566 via ALMA observations of the CO J:2-1 emission at 24pc spatial and ~2.6km/s spectral resolution, and Gemini-GMOS/IFU observations of ionized gas emission lines and stellar absorption lines at similar spatial resolution, and 123km/s of intrinsic spectral resolution. The morphology and kinematics of stellar, molecular (CO), and ionized ([NII]) emission lines are compared to the expectations from rotation, outflows, and streaming inflows. While both ionized and molecular gas show rotation signatures, there are significant non-circular motions in the innermost 200pc and along spiral arms in the central kpc (CO). The nucleus shows a double-peaked CO profile (full width at zero intensity of 200km/s), and prominent (~80km/s) blue- and redshifted lobes are found along the minor axis in the inner arcseconds. Perturbations by the large-scale bar can qualitatively explain all features in the observed velocity field. We thus favor the presence of a molecular outflow in the disk with true velocities of ~180km/s in the nucleus and decelerating to 0 by ~72pc. The implied molecular outflow rate is 5.6M_{Sun}_/yr, with this gas accumulating in the nuclear 2" arms. The ionized gas kinematics support an interpretation of a similar but more spherical outflow in the inner 100pc, with no signs of deceleration. There is some evidence of streaming inflows of ~50km/s along specific spiral arms, and the estimated molecular mass inflow rate, ~0.1M_{Sun}_/yr, is significantly higher than the SMBH accretion rate (dM/dt=4.8x10^-5^M_{Sun}_/yr).2019A&A...621A..83Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/621/A83CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/621/A83https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/621/A83http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/621/A83https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/621/A83https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/621/A83http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/621/A83GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/621/A83/gen (General quantities of NGC 1566 obtained)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/621/A83/gen?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/621/A83/gen?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/621/A83/gen?GETtext/xml+votable180.050000true65.00175-54.937810.005555555555555556Cone search capability for table J/A+A/621/A83/list (List of fits datacubes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/621/A83/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/621/A83/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/621/A83/list?GETtext/xml+votable180.050000true65.00144-54.938110.0055555555555555566/33958https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/621/A83?format=asciiOpticalRadiodefaultJ/A+A/621/A83/genGeneral quantities of NGC 1566 obtainedrecnoRecord number assigned by the VizieR team.
