Most of the data have been gathered between February 2012 and April 2015 but for some sources even longer light curves exist. The detection rate at 37GHz is around 19%, which is comparable to other populations of active galactic nuclei presumed to be faint at radio frequencies, such as BL Lac objects. Variability and spectral indices are determined for sources with enough detections. Based on the radio data, many NLS1 galaxies show a blazar-like radio spectra exhibiting significant variability. The spectra at a given time are often inverted or convex. The source of the high-frequency radio emission in NLS1 galaxies, detected at 37GHz, is most probably a relativistic jet rather than star formation. Jets in NLS1 galaxies are therefore expected to be a much more common phenomenon than earlier assumed.</description><source format="bibcode">2017A&amp;A...603A.100L</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/603/A100</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/AJ/124/3042">J/AJ/124/3042 : Narrow-line Seyfert 1 galaxies from SDSS EDR (Williams+, 2002)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/459/55">J/A+A/459/55 : Narrow-band imaging of 5 Seyfert-1 galaxies (Bennert+, 2006)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/AJ/131/1948">J/AJ/131/1948 : Narrow line Seyfert 1 galaxies in the FBQS (Whalen+, 2006)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/AJ/132/321">J/AJ/132/321 : Morphology of narrow-line Seyfert 1 galaxies (Deo+, 2006)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/166/128">J/ApJS/166/128 : Narrow line Seyfert 1 galaxies from SDSS-DR3 (Zhou+, 2006)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/AJ/143/83">J/AJ/143/83 : Properties of a sample of Seyfert 1 galaxies (Xu+, 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/573/A76">J/A+A/573/A76 : Multifrequency study of NL Seyfert 1 galaxies (Jarvela+, 2015)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/575/A55">J/A+A/575/A55 : Radio jet emission from GeV-emitting NLSy1 (Angelakis+, 2015)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/588/A146">J/A+A/588/A146 : The gNLS1 galaxy PKS 2004-447.
