cds-question@unistra.frseyfert-galaxiesquasarsspectroscopyWe present results from the analysis of the optical spectra of 47 radio-selected narrow-line Seyfert 1 (NLS1) galaxies. These objects are a subset of the First Bright Quasar Survey (Cat. <J/AJ/112/407>) and were initially detected at 20cm (flux density limit 1Jy) in the VLA FIRST Survey.2006AJ....131.1948Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/1948CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/112/407 : The FIRST bright QSO survey (Gregg+, 1996)J/ApJS/126/133 : The FIRST bright quasar survey.
