cds-question@unistra.fractive-galactic-nucleiquasarsx-ray-sourcesblack-holesWe present the X-ray analysis of coronal properties in a statistically representative sample of 23 mostly radio-quiet active galactic nuclei (AGN) from the SUpermassive Black holes Winds in X-rAYs campaign (SUBWAYS), focusing on quasars at redshifts 0.1<z<0.4 and bolometric luminosities 2x10^44^<Lbol(erg/s)<2x10^46^. The main aim of this work is to investigate the properties of the hot corona through the study of the hard X-ray band emission, including a proper treatment of the soft X-ray band. High-quality X-ray spectra from XMM-Newton, complemented by NuSTAR data extending up to 30-40keV in the rest frame, are available for this sample. The soft X-ray band (0.3-2keV) spectrum is best fit by a warm corona model with a median temperature of ~0.40keV, and an optical depth in the range tau~20-40, consistent with previous results on lower-luminosity sources. The hard X-ray band is well described using a hot corona model, with a median high-energy cutoff of ~87keV; 11 out of 23 of the sources have well constrained values at the lower end of the distribution of typical values found in Seyfert galaxies (~100-200keV). The derived median value of the optical depth (tau~105) suggests the presence of a moderately optically thick corona. By combining the SUBWAYS results with literature samples at low and high redshifts, we assembled the largest sample to date of AGN with Ecut and accretion parameter measurements, finding a significant anticorrelation of Ecut with both {lambda}Edd and Lbol with the median Ecut decreasing from ~250-300keV at low accretion rates and luminosities to ~90-100keV at high accretion rates and luminosities; this is consistent with increased coronal cooling, possibly driven by pair production. These results favor cooler, optically thicker coronae in luminous AGN compared to those in lower-luminosity Seyfert galaxies.2026A&A...712A..57Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/712/A57CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/712/A57https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/712/A57http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/712/A57https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/712/A57https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/712/A57http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/712/A57GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/712/A57/tablea1 (XMM-Newton and NuSTAR observation log)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/712/A57/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/712/A57/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/712/A57/tablea1?GETtext/xml+votable180.050000true13.717159725.42749530.005555555555555556Cone search capability for table J/A+A/712/A57/tablea3 (AGN from the literature)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/712/A57/tablea3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/712/A57/tablea3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/712/A57/tablea3?GETtext/xml+votable180.050000true186.453597233.54686110.0055555555555555566/134 1405 3309 4540 5333 5379 5533 5576 5687 5731 5825 5975 6591 6923 7168 7309 7424 7642 7713 7921 8029 8071 8299 8324 8812 8845 8922 8927 8941 9855 10118 10162 10401 10709 10927 11490 13414 14534 14541 14744 14858 15433 15481 16095 16301 16333 16962 17075 17668 17814 19017 19283 19883 19932 21450 22851 22890 24831 25090 25182 25580 25585 25907 25965 26019 26041 26148 26393 26509 27382 27477 27501 27720 27767 27787 27803 27862 28148 28275 28471 28517-28518 28535 28848 29398 29795 31158 31401 31465 32344 32447 32658 33282 33394 34034 34065 34730 34768 34881 36775 36786 37913 38221 38268 38653 38868 39118 39295 40818 41014 41736 41929 43064 43546 43806 43877 44507 44785 44988 45735 46399 46544 46615 48394 49042https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/712/A57?format=asciiX-raydefaultJ/A+A/712/A57/tablea1XMM-Newton and NuSTAR observation logrecnoRecord number assigned by the VizieR team.
