This is the case at low luminosities, when the jet-corona coupling dominates the energy output in both populations. Previous attempts to extend this framework to a wider AGN population have been extremely challenging due to heavy hydrogen absorption of the accretion disc continuum and starlight contamination from the host galaxies. We present the luminosity-excitation diagram (LED), based on the [O IV]_25.9um_ and [Ne II]_12.8um_ mid-infrared nebular line fluxes. This tool enables to probe the accretion disc contribution to the ionizing continuum. When applied to a sample of 167 nearby AGN, the LED recovers the characteristic q-shaped morphology outlined by individual X-ray binaries during a typical accretion episode, allowing us to tentatively identify the main accretion states. The soft state would include broad-line Seyferts and about half of the Seyfert 2 population, showing highly excited gas and radio-quiet cores consistent with disc-dominated nuclei, in agreement with previous studies. The hard state mostly includes low-luminosity AGN (<= 10-3^ LEdd) characterized by low-excitation radio-loud nuclei and a negligible disc contribution. The remaining half of Seyfert 2 nuclei and the bright LINERs show low excitation at high accretion luminosities and could be identified with the bright hard and intermediate states. Their hosts show ongoing star formation in the central kiloparsecs. We discuss the above scenario, its potential links with the galaxy evolution picture, and the possible presence of accretion state transitions in AGN, as suggested by the growing population of changing-look quasars.2021MNRAS.504.5726Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/504/5726CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/157 : The Extended 12um galaxy sample (Rush+ 1993)J/ApJS/226/19 : FIR spectra of AGNs from HerschelJ/MNRAS/398/1165 : AGN in nearby galaxies (Goulding+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/504/5726https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/504/5726http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/504/5726https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/504/5726https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/504/5726http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/504/5726GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/504/5726/table1 (Seyfert and LINER galaxies compiled for this study)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/504/5726/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/504/5726/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/504/5726/table1?GETtext/xml+votable180.050000true0.79001583321.9602240.0055555555555555566/941 953 1008 1701-1702 1918 2248 2251 2309 2564 3446 4215 4439 4992 5975 6093 6977 7214 7225 7241 7424 7552 7606 7642 7713 7869 7921 8264 8410 8492 8845 8922 8989 9468 9882 10039 10355 10364 10404 10465 10475 10487 10637 10841 10856 10912 10924 10977 11006 11027 11101 11246 11490 11512 12335 13021 13120 13522 14744 17525 17529 17727 17748 17754-17755 17819 18365 18387 18683 18794 18897 19283 19296 19619 19730 19883 20208 20230 21016 22632 22654 23171 23323 24123 24842 24896 25083 25518 25610 25790 25907 26148 26175 26198 26292 26491 27030 27191 27255 27426 27512 27704 27714 27765 27767 27773 27914 27937 27942 27945 28045 28123 28154 28167 28184 28495 28517 28529 30027 31158 31430 33958 34294 34531 34534 34913 35623 35691 35993 36618 36716 36733 36785 36861 36896 38268 38868 40410 40777 40818 41059 43262 43626 43634 43677 43748 43806 43877 43925 44448 44507 44660 45735 45779 45883 46399 46442 46615 46811 46987 47047 47154 49042https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/504/5726?format=asciiX-rayInfrareddefaultJ/MNRAS/504/5726/table1Seyfert and LINER galaxies compiled for this studySimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
