cds-question@unistra.frquasarsredshiftedspectroscopyline-intensitiesOutflows from active galactic nuclei are invoked as the principal feedback process regulating the co-evolution of supermassive black holes and their host galaxies. Because of their multi-phase and multi-scale nature, an exhaustive description of these winds should exploit multiple tracers. However, connecting various outflow features remains a challenge. The aim of this work is to provide a complete characterisation of outflows in a sample of z~5 quasars, by exploiting the combination of different emission and absorption tracers. We analysed the UV/optical and FIR continuum, line emission, and absorption in a sample of 39 z~5 quasars observed with VLT/X-Shooter and ALMA (available for six objects). We identified broad and narrow absorption lines associated with the quasar and emission lines to determine black hole masses and bolometric luminosities. Our sample encompasses massive (M_BH,MgII_=10^8.5-10^M_{sun}_) and luminous (L_bol_=10^46.9-48^erg/s) quasars at redshift 5~5.7. They display powerful ionised outflows detected in both emission and absorption, with velocities exceeding 48000km/s in some cases, and lie above the local black hole - host galaxy mass relation, exhibiting a behaviour similar to that of z~6 quasars. These findings suggest a phase of efficient black hole feedback occurring at redshift z~6 and likely persisting down to z~5, characterised by rapid black hole growth exceeding that of the host galaxy. The fraction of quasars with outflow detections in absorption is higher for larger CIV-MgII velocity shifts, suggesting that while the physical mechanisms powering the two outflow phenomena detected in emission and absorption may differ, a correlation exists between them.2025A&A...698A.145Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/698/A145CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/698/A145https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/698/A145http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/698/A145https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/698/A145https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/698/A145http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/698/A145GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/698/A145/tablea1 (Properties of our CIV absorption systems)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/698/A145/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/698/A145/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/698/A145/tablea1?GETtext/xml+votable180.050000true42.83887643.55483190.0055555555555555566/33 42 424 717 4224 4466 4872 5153 8722 8819 12567 17252 17382 17691 17989 18222 18706 19008 19067 19507 19622 21989 22393 23191 26962 27359 27901 44391https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/698/A145?format=asciidefaultJ/A+A/698/A145/tablea1Properties of our CIV absorption systemsrecnoRecord number assigned by the VizieR team.
