Basic properties of Narrow-Line Seyfert 1 Galaxies with Relativistic Jets
Abstract
We present the preliminary results of a survey performed with Swift to observe a sample of radio-loud Narrow-Line Seyfert 1 Galaxies (RLNLS1s). Optical-to-X-ray data from Swift are complemented with gamma-ray observations from Fermi/LAT and radio measurements available in the literature. The comparison with a sample of bright Fermi blazars indicates that RLNLS1s seem to be the low-power tail of the distribution.

The old displayed values were luminosity densities (Lnu) instead of nuLnu. Now, the figures display the corrected values. Nothing changes in the concepts
