cds-question@unistra.fractive-galactic-nucleiquasarsseyfert-galaxiesWe study the morphological and structural properties of the host galaxies associated with 57 optically selected luminous type 2 active galactic nuclei (AGNs) at z~0.3-0.4: 16 high-luminosity Seyfert 2 [HLSy2, 8.0=<log(L_[OIII]_/L_{sun}_)<8.3] and 41 obscured [QSO2, log(L_[OIII]_/L_{sun}_)>=8.3] quasars. With this work, the total number of QSO2s at z<1 with parametrized galaxies increases from ~35 to 76. Our analysis is based on Hubble Space Telescope WFPC2 and ACS images that we fit with galfit. HLSy2s and QSO2s show a wide diversity of galaxy hosts. The main difference lies in the higher incidence of highly disturbed systems among QSO2s. This is consistent with a scenario in which galaxy interactions are the dominant mechanism triggering nuclear activity at the highest AGN power. There is a strong dependence of galaxy properties with AGN power (assuming L_[OIII]_ is an adequate proxy). The relative contribution of the spheroidal component to the total galaxy light (B/T) increases with L_[OIII]_. While systems dominated by the spheroidal component spread across the total range of L_[OIII]_, most disc-dominated galaxies concentrate at log(L_[OIII]_/L_{sun}_)<8.6. This is expected if more powerful AGNs are powered by more massive black holes which are hosted by more massive bulges or spheroids. The average galaxy sizes (<r_e_>) are 5.0+/-1.5kpc for HLSy2s and 3.9+/-0.6kpc for HLSy2s and QSO2s, respectively. These are significantly smaller than those found for QSO1s and narrow-line radio galaxies at similar z. We put the results of our work in the context of related studies of AGNs with quasar-like luminosities.2019MNRAS.483.1829Uhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/483/1829CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/483/1829https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/483/1829http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/483/1829https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/483/1829https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/483/1829http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/483/1829GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/483/1829/table1 (List of objects observed for the HST programme 10880)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/483/1829/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/483/1829/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/483/1829/table1?GETtext/xml+votable180.050000true6.3810761-10.67284690.0055555555555555566/553 4102 4711 4716 5016 5806 5877 6009 6096 6403 6430 6470 6542 7284 7434 7467 7479 10075 10087 10202 11344 11456 12556 17229 17497 17725-17726 17770 17773 18009 18019 18390 18792 18860 19052 19994 21855 22009 23060 23189 23194 23196 23205 23216 25953 25973 26018 26058 27304 27313 31295 31338 36792https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/483/1829?format=asciidefaultJ/MNRAS/483/1829/table1List of objects observed for the HST programme 10880SimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
