cds-question@unistra.frquasarsradio-sourcesWe present the stacking analysis of a sample of 48 quasi-stellar objects (QSOs) at 4.5<z<7.1 detected by the Atacama Large Millimetre Array (ALMA) in the [CII] {lambda}158um emission line to investigate the presence and the properties of massive, cold outflows associated with broad wings in the [CII] profile. The high sensitivity reached through this analysis allows us to reveal very broad [CII] wings tracing the presence of outflows with velocities in excess of 1000km/s. We find that the luminosity of the broad [CII] emission increases with LAGN, while it does not significantly depend on the star formation rate of the host galaxy, indicating that the central active galactic nucleus (AGN) is the main driving mechanism of the [CII] outflows in these powerful, distant QSOs. From the stack of the ALMA cubes, we derive an average outflow spatial extent of ~3.5kpc. The average atomic neutral mass outflow rate inferred from the stack of the whole sample is dM_out_/dt~100M_{sun}_/yr, while for the most luminous systems it increases to ~200M_{sun}_/yr. The associated outflow kinetic power is about 0.1% of L_AGN_, while the outflow momentum rate is ~L_AGN_/c or lower, suggesting that these outflows are either driven by radiation pressure onto dusty clouds or, alternatively, are driven by the nuclear wind and energy conserving but with low coupling with the interstellar medium. We discuss the implications of the resulting feedback effect on galaxy evolution in the early Universe.2019A&A...630A..59Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/630/A59CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/630/A59https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/630/A59http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/630/A59https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/630/A59https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/630/A59http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/630/A59GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/630/A59/list (List of fits datacubes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/630/A59/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/630/A59/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/630/A59/list?GETtext/xml+votable180.050000true13.76211.771590.0055555555555555566/4176 4279 4641 8211 8553 16531 16554 17236 17358 17663 17701 18031 18155 18644 19412 19440 20116 25330 25849 25977 26031 26080 26204 26239 26524 26869 26973 27022 27041 27124 27324 27426 27676 27700 30036 34187 34762 35615 35727 35895 36182 36725 44429 44463 44753 46589 48715 48899https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/630/A59?format=asciiRadiodefaultJ/A+A/630/A59/listList of fits datacubesSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
