Beginning of ReadMe : J/A+A/591/A88 [OIII] of radio-emitting narrow-line Seyfert 1 (Berton+, 2016) ================================================================================ [O III] line properties in two samples of radio-emitting narrow-line Seyfert 1 galaxies. Berton M., Foschini L., Ciroi S., Cracco V., La Mura G., Di Mille F., Rafanelli P. <Astron. Astrophys., 591, A88 (2016)> =2016A&A...591A..88B (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Galaxies, Seyfert ; QSOs ; Galaxies, radio Keywords: galaxies: Seyfert - galaxies: jets - quasars: emission lines Abstract: The [OIII] lambdalambda 4959, 5007 lines are a useful proxy to test the kinematic of the narrow-line region (NLR) in active galactic nuclei (AGN). In AGN, and particularly in narrow-line Seyfert 1 galaxies (NLS1s) these lines often show few peculiar features, such as blue wings, often interpreted as outflowing component, and a shift - typically toward lower wavelengths - of the whole spectroscopic feature in some exceptional sources, the so-called blue outliers, which are often associated to strong winds. We investigated the incidence of these peculiarities in two samples of radio-emitting NLS1s, one radio-loud and one radio-quiet. We also studied a few correlations between the observational properties of the [OIII] lines and those of the AGN. Our aim was to understand the difference between radio-quiet and radio-loud NLS1s, which may in turn provide useful information on the jet formation mechanism. We find that the NLR gas is much more perturbed in radio-loud than in radio-quiet NLS1s. In particular the NLR dynamics in gamma-ray emitting NLS1s appears to be highly disturbed, and this might be a consequence of interaction with the relativistic jet. The less frequently perturbed NLR in radio-quiet NLS1s suggests instead that these sources likely do not harbor a fully developed relativistic jet. Nonetheless blue-outliers in radio-quiet NLS1s are observed, and we interpret them as a product of strong winds. Description: We decided to use the sample created by Cracco et al. (2016, MNRAS, submitted) to have a uniformly selected sample of RQNLS1s that is not contaminated by any spurious source. They found 9 RLNLS1s, which we included in our second sample, and 59 RQNLS1s. To further increase the number of sources, we decided to add also the RQNLS1s from Berton et al. (2015A&A...578A..28B), which were not already included in their sample because of the selection criteria and had a suitable spectra to analyze. Our RQNLS1s sample in conclusion is made of 68 RQNLS1s. For the RLNLS1s sample, besides the nine sources we already found with the previous selection, we decided to use all the sources analyzed by Foschini et al. (2015A&A...575A..13F) and Berton et al. (2015A&A...578A..28B) for which an optical spectrum was available in SDSS DR12, in the NED archive, or observable with the Asiago 1.22m telescope (Sect. 3.1). Our sample is comprised of 56 RLNLS1s.
