cds-question@unistra.frquasarsinfrared-astronomyspectroscopyQuasars accreting at very high rates are believed to be prime movers of galactic evolution because of their high radiative and mechanical output. The study presented in this paper investigates a sample of six highly accreting quasars at redshifts (z=2-3) using near-infrared observations from the LUCI spectrograph at the Large Binocular Telescope (LBT). The aim is obtain a precise measure of the quasar systemic redshift and accretion parameters (black hole mass and Eddington ratio) primarily from the H{beta} line, and on second stance from other intermediate and low ionization lines. Outflow dynamical parameters (mass rate of outflowing gas, its kinetic power and momentum rate) were estimated from the CIV emission line that is perhaps the most easily accessible tracer of high-ionization winds from the accretion disk, obtained from the Sloan Digital Sky Survey. In addition, the joint analysis of the rest-frame optical and UV spectra allowed us to estimate the chemical composition of the broad line emitting gas. The high metal content of the outflowing gas (Z>~10Z_{sun}_) and the high values of thrust and kinetic power may induce a chemical feedback effect in the quasar host, in addition to mechanical feedback.2025MNRAS.540..562Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/540/562CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/540/562https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/540/562http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/540/562https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/540/562https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/540/562http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/540/562GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/540/562/table1 (Source identification and basic properties of the LUCI-LBT sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/540/562/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/540/562/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/540/562/table1?GETtext/xml+votable180.050000true131.2613758.20397220.0055555555555555566/4242 4959 5185 11307 11932 491061.1166583743361574e-19 4.653515163505597e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/540/562?format=asciiInfrareddefaultJ/MNRAS/540/562/table1Source identification and basic properties of the LUCI-LBT samplerecnoRecord number assigned by the VizieR team.
