cds-question@unistra.frseyfert-galaxiesgalaxiesvisible-astronomyspectroscopyWe present optical and near-infrared (NIR) imaging data of the radio-loud, narrow-line Seyfert 1 galaxy 1H 0323+342, which shows intense and variable gamma-ray activity discovered by the Fermi satellite with the Large Area Telescope. Near-infrared and optical images are used to investigate the structural properties of the host galaxy of 1H 0323+342; this together with optical spectroscopy allows us to examine its black hole mass. Based on two-dimensional (2D) multiwavelength surface-brightness modeling, we find that statistically, the best model fit is a combination of a nuclear component and a Sersic profile (n~2.8). However, the presence of a disk component (with a small bulge n~1.2) also remains a possibility and cannot be ruled out with the present data. Although at first glance a spiral-arm-like structure is revealed in our images, a 2D Fourier analysis of the imagery suggests that this structure corresponds to an asymmetric ring, likely associated with a recent violent dynamical interaction. We discuss our results in the context of relativistic jet production and galaxy evolution.2014ApJ...795...58Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/795/58CatalogResearchIsServedByTAP VizieR generic servicerelated-toVII/173 : Catalogue of Seyfert Galaxies (Lipovetsky+, 1988)J/A+A/459/55 : Narrow-band imaging of 5 Seyfert-1 galaxies (Bennert+, 2006)J/AJ/143/83 : Properties of a sample of Seyfert 1 galaxies (Xu+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/795/58https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/795/58http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/795/58https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/795/58https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/795/58http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/795/58GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/795/58/fig2*Rest frame optical spectrum of 1H 0323+342, taken with the GHAO on 17th September 2012recnoRecord number assigned by the VizieR team.
