cds-question@unistra.frquasarsgalaxiesspectroscopyvisible-astronomyWe use MUSE adaptive optics (AO) data in Narrow Field Mode to study the properties of the ionised gas in MR 2251-178 and PG 1126-041, two nearby (z~0.06) bright quasars hosting sub-pc scale Ultra Fast Outflows (UFOs) detected in the X-ray band. We decompose the optical emission from diffuse gas into a low- and a high-velocity components. The former is characterised by a clean, regular velocity field and a low (~80 km/s) velocity dispersion. It traces regularly rotating gas in PG 1126-041, while in MR 2251-178 it is possibly associated to tidal debris from a recent merger or flyby. The other component is found to be extended up to a few kpc from the nuclei, and shows a high (~800km/s) velocity dispersion and a blue-shifted mean velocity, as expected from AGN-driven outflows. We estimate mass outflow rates up to a few Mo/yr and kinetic efficiencies between 0.1-0.4 per cent, in line with those of galaxies hosting AGNs of similar luminosity. The momentum rates of these ionised outflows are comparable to those measured for the UFOs at sub-pc scales, consistent with a momentum-driven wind propagation. Pure energy-driven winds are excluded unless about 100x additional momentum is locked in massive molecular winds. By comparing the outflow properties of our sources with those of a small sample of well-studied QSOs hosting UFOs from the literature, we find that winds seem to systematically lie either in a momentum-driven or in an energy-driven regime, indicating that these two theoretical models bracket very well the physics of AGN-driven winds.2020A&A...644A..15Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/644/A15CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/644/A15https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/644/A15http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/644/A15https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/644/A15https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/644/A15http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/644/A15GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/644/A15/list (List of fits datacubes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/644/A15/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/644/A15/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/644/A15/list?GETtext/xml+votable180.050000true343.52473-17.581720.0055555555555555566/17075 26902https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/644/A15?format=asciiOpticaldefaultJ/A+A/644/A15/listList of fits datacubesrecnoRecord number assigned by the VizieR team.
