TL;DR
This study investigates the properties of radio-loud Narrow-Line Seyfert 1 Galaxies with relativistic jets using multiwavelength data, revealing they are the low-power extension of blazar populations.
Contribution
First comprehensive multiwavelength survey of RLNLS1s with relativistic jets, highlighting their position as low-power counterparts to blazars.
Findings
RLNLS1s are the low-power tail of the blazar distribution.
Optical, X-ray, gamma-ray, and radio data show similarities with blazar properties.
Preliminary results suggest RLNLS1s have relativistic jets akin to those in blazars.
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.
