cds-question@unistra.fractive-galactic-nucleiradio-galaxiesseyfert-galaxiesWe have detected six narrow-line Seyfert 1 (NLS1) galaxies at 37GHz that were previously classified as radio silent and two that were classified as radio quiet. These detections reveal the presumption that NLS1 galaxies labelled radio quiet or radio silent and hosted by spiral galaxies are unable to launch jets to be incorrect. The detections are a plausible indicator of the presence of a powerful, most likely relativistic jet because this intensity of emission at 37GHz cannot be explained by, for example, radiation from supernova remnants. Additionally, one of the detected NLS1 galaxies is a newly discovered source of gamma rays and three others are candidates for future detections.2018A&A...614L...1Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/614/L1CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/573/A76 : Multifrequency study of NL Seyfert 1 galaxies (Jarvela+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/614/L1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/614/L1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/614/L1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/614/L1https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/614/L1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/614/L1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap2.4516457410139638e-23 2.4516457410139638e-23RadiodefaultJ/A+A/614/L1/table1Basic data and statistics of 37GHz and gamma-ray observationsSimbadNameSimbad column added by the CDSmeta.idcharzRedshiftsrc.redshiftfloatrecnoRecord number assigned by the VizieR team.
