cds-question@unistra.frseyfert-galaxiesgalaxiesinfrared-sourcesHalf of the Seyfert-2 galaxies escaped detection of broad lines in their polarised spectra observed so far. Some authors have suspected that these non-HBLRs contain real Sy2 nuclei without intrinsic broad line region hidden behind a dust torus. If this were true, then their nuclear structure would fundamentally differ from that of Sy2s with polarised broad lines: in particular, they would not be explained by orientation-based AGN unification. Further arguments for two physically different Sy2 populations have been derived from the warm and cool IRAS F25/F60 ratios. These ratios, however, refer to the entire host galaxies and are unsuitable to conclusively establish the absence of a nuclear dust torus. Instead, a study of the Seyfert-2 dichotomy should be performed on the basis of nuclear properties only. Here we present the first comparison between [OIII] {lambda} 5007{AA} and mid-infrared imaging at matching spatial resolution. The aim is to check whether the nuclear dust emission scales with AGN luminosity as traced by [OIII].2007A&A...473..369Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/473/369CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)VIII/71 : The FIRST Survey Catalog, Version 03Apr11 (Becker+ 2003)II/156 : IRAS Faint Source Catalog |b|>10, Version 2.0 (Moshir+ 1989)J/AJ/126/1607 : IRAS Revised Bright Galaxy Sample (Sanders+, 2003)J/ApJS/98/477 : Optical spectral atlas of Seyfert nuclei (Ho+ 1995)J/ApJS/112/315 : Spectroscopic parameters of Seyfert nuclei (Ho+ 1997)J/ApJS/141/23 : JHK' imaging photometry of Seyfert 1.
