cds-question@unistra.frquasarsredshiftedinfrared-photometryBright quasars, powered by accretion onto billion-solar-mass black holes, already existed at the epoch of reionization, when the Universe was 0.5-1 billion years old. How these black holes formed in such a short time is the subject of debate, particularly as they lie above the correlation between black-hole mass and galaxy dynamical mass in the local Universe. What slowed down black-hole growth, leading towards the symbiotic growth observed in the local Universe, and when this process started, has hitherto not been known, although black-hole feedback is a likely driver. Here we report optical and near-infrared observations of a sample of quasars at redshifts 5.8<~z<~6.6. About half of the quasar spectra reveal broad, blueshifted absorption line troughs, tracing black-hole-driven winds with extreme outflow velocities, up to 17% of the speed of light. The fraction of quasars with such outflow winds at z>~5.8 is ~2.4 times higher than at z>~2-4. We infer that outflows at z>~5.8 inject large amounts of energy into the interstellar medium and suppress nuclear gas accretion, slowing down black-hole growth. The outflow phase may then mark the beginning of substantial black-hole feedback. The red optical colours of outflow quasars at z>~5.8 indeed suggest that these systems are dusty and may be caught during an initial quenching phase of obscured accretion.2022Natur.605..244Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/Nat/605.244CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/Nat/605.244https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/Nat/605.244http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/Nat/605.244https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/Nat/605.244https://vizier.iucaa.in/viz-bin/votable?-source=J/other/Nat/605.244http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/Nat/605.244GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/Nat/605.244/table1 (The XQR-30 properties and BAL system parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/Nat/605.244/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/Nat/605.244/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/Nat/605.244/table1?GETtext/xml+votable180.050000true7.02733334.95712220.0055555555555555566/471 4279 8598 12576 17236 17358 17504 17654 18155 20116 21263 22424 23304 25375 26650 27327 27676 30849 30906 33271 34762 35100 35304 35675 44429 44753 44984 46284 46983 483135.3455714667354156e-20 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/Nat/605.244?format=asciiInfrareddefaultJ/other/Nat/605.244/table1The XQR-30 properties and BAL system parametersSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
