cds-question@unistra.frquasarsredshiftedradio-sourcesinfrared-astronomyspectroscopyDespite the increasing prevalence of radio-loud (RL) sources at cosmic noon, our understanding of the underlying physics that governs the accretion disc outflows in these particular sources and its dissimilarity with radio-quiet (RQ) quasars remains somewhat limited. Disentangling the real impact of the radio-loudness and accretion on the outflow parameters remains a challenge to this day.We present 10 new spectra of high-redshift and high-luminosity quasars and combine it with previous data at both high and low redshift with the aim to evaluate the role of the feedback from RL and RQ AGN. The final high-redshift (1.5<~z<~3.9) high-luminosity (47.1<=log(L)<=48.5) sample consists of a combination of 60 quasars from our ISAAC and the Hamburg-ESO surveys. The low-redshift (z<=0.8) sample has 84 quasars with optical and Faint Object Spectrograph (FOS) reanalyzed data. We perform a multicomponent analysis of optical and UV emission line profiles along the quasar main sequence, and provide a relation to estimate the outflow main parameters (mass rate, thrust and kinetic power) in both the BLR and NLR through the analysis of the [OIII]{lambda}5007 and CIV{lambda}1549 emission lines. Spectrophotometric properties and line profile measurements are presented for H{beta}+[OIII]{lambda}{lambda}4959,5007, SiIV{lambda}1397+OIV]{lambda}1402, CIV{lambda}1549+HeII{lambda}1640, and the 1900{AA} blend. High-ionization lines as such CIV{lambda}1549 and [OIII]{lambda}5007 usually present a significant asymmetry towards the blue especially in radio-quiet sources that is strong evidence of outflow motions. In the ISAAC sample, 72% of the quasars where [OIII] is clearly detected present significant outflows, with centroid velocity at half intensity blueshifted to values greater than ~250km/s. Radio-loud quasars tend to present slightly more modest blueshifted components in both the UV and optical ranges. The behavior of [OIII]{lambda}5007 mirrors the one of CIV{lambda}1549, with blueshift amplitudes between the two lines showing a high degree of correlation that appears unaffected by the presence of radio emission. In contrast to low redshift, both RL and RQ AGN outflow parameters at high luminosity appear in the range needed to provide feedback effects on their host galaxies. Both high- and low-z RL quasars exhibit smaller outflows compared to RQ, suggesting a potential role of radioloudness in mitigating outflow effects. Nevertheless, the radio-loudness effect on the AGN feedback is much less significant than the one of accretion that emerges as the main driver of the nuclear outflows.2024A&A...691A..15Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/691/A15CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/669/A83 : High-redshift quasars spectra (Deconto-Machado+, 2023)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/691/A15https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/691/A15http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/691/A15https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/691/A15https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/691/A15http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/691/A15GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/691/A15/table1 (Source identification)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/691/A15/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/691/A15/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/691/A15/table1?GETtext/xml+votable180.050000true37.2219167-3.61813890.005555555555555556Cone search capability for table J/A+A/691/A15/table2 (Identification of the sources, radio properties, and results of the UV and optical parameters obtained through the re-analysis by multi-component fitting and used in this study for both the HEMS and FOS samples)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/691/A15/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/691/A15/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/691/A15/table2?GETtext/xml+votable180.050000true9.527083-28.6136110.0055555555555555566/1701 4285 4341 4439 5262 5306 5312 5437 5439 5481 5576 5597 5687 5722 5731 5767 6264 7176 7488 7642 8017 8528 8641 8812 8845 8858 8906 8922 8927 8941 9181 9194 9262 9459 9633 9750 9955 9959 10162 10217 10472 10578 10694 10709 11203 11217 11829 12317 13414 13496 16093 16386 16417 16477 16691 17075 17488 17693 18041 18125 18506 18769 18948 19283 19287 19315 19609 19700 19730 19746 19883 21060 22658 22890 25245 25742 26021 26050 26292 26509 26735 26960 26990 26996 27023 27269 27349 27560 27720 27862 28216 28356 28471 28517 31652 33684 34291 34299 34306 34424 34578 34672 35128 35275 35595 35627 35723 35875 36417 40131 40272 40343 40446 43903 44043 44269 46404 46701 46839 47038 48965 490421.1166583743361574e-19 1.2918781580533825e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/691/A15?format=asciiInfraredRadiodefaultJ/A+A/691/A15/table1Source identificationrecnoRecord number assigned by the VizieR team.
