cds-question@unistra.fractive-galactic-nucleispectroscopyMany active galactic nuclei (AGN) and particularly narrow line Seyfert 1 (NLS1) galaxies, usually exhibit blueshifts and blue wings in several emission lines, which are mainly associated to outflows and strong winds. Although there is no clear evidence of the physical origin of the [OIII] blue wings, it has been suggested that they could be emitted from the inner parts of the narrow line region (NLR). In order to study the radial velocity difference between the narrow component of H{beta} and the core component of [OIII]{lambda}5007 and the asymmetric emission of this forbidden line, we investigate a sample of NLS1 galaxies. One of the aims of this paper is to analyze the blue wings of the [OIII]{lambda}5007 profiles and their relation with the central engine. We have obtained and studied medium-resolution spectra (190km/s FWHM at H{beta}) of a sample of 28 NLS1 galaxies in the optical range 4300-5200{AA}. We performed Gaussian decomposition to the H{beta} and [OIII]{lambda}{lambda}4959,5007 emission profiles in order to study the distinct components of these lines. A new blue outlier galaxy is found, with the center of the core component of [OIII] blueshifted by 405km/s relative to the center of the narrow component of H{beta} line. We confirmed a previously known correlation between the blueshift and the FWHM of the core component of [OIII]{lambda}5007 line. We also corroborated the correlation between the latter and the velocity of the centroid of the blue wing. On the other hand, studying the radial velocity difference between the blue end of the asymmetric emission and the centroid of the core component of [OIII], we found a correlation between it and the central black hole mass and, therefore, with the luminosity of the broad component of H{beta}. Finally, we found a moderate correlation between the luminosity of the [OIII] blue wing and the black hole mass. These results suggest that the asymmetric emission of the [OIII] lines is related to the central engine, not only through the black hole but also in the intensity of the AGN, in agreement with previous results.2018A&A...615A..13Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/615/A13CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/615/A13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/615/A13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/615/A13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/615/A13https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/615/A13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/615/A13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/615/A13/tablea1 (Observed galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/615/A13/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/615/A13/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/615/A13/tablea1?GETtext/xml+votable180.050000true61.1803333-29.889750.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/615/A136/8215 17427 17627 18592 18865 19533 21038 21766 23385 25992 27074 29346 31323 33623 33662 34725 35001 38758 39073 40258 40902 43399 44008 45500 46143 48282 48370 48594https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/615/A13?format=asciidefaultJ/A+A/615/A13/tablea1Observed galaxiesSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
