cds-question@unistra.fractive-galactic-nucleiinfrared-astronomyspectroscopySeveral authors have claimed that less luminous active galactic nuclei (AGNs) are not capable of sustaining a dusty torus structure. Thus, a gradual resizing of the torus is expected when the AGN luminosity decreases. Our aim is to examine mid-infrared observations of local AGNs of different luminosities for the gradual resizing and disappearance of the torus. We applied the decomposition method described by Hernan-Caballero+ (2015, J/ApJ/803/109) to a sample of ~100 Spitzer/IRS spectra of low-luminosity AGNs and powerful Seyferts in order to decontaminate the torus component from other contributors. We have also included Starburst objects to ensure secure decomposition of the Spitzer/IRS spectra. We have used the affinity propagation (AP) method to cluster the data into five groups within the sample according to torus contribution to the 5-15{mu}m range (C_torus_) and bolometric luminosity (L_bol_).2017ApJ...841...37Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/841/37CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/258 : Quasars and Active Galactic Nuclei (13th Ed.)
