Abstract:
High-energy γ-rays, which are produced by powerful relativistic
jets, are usually associated with blazars and radio galaxies. In the
current active galactic nuclei (AGN) paradigm, such jets are almost
exclusively launched from massive elliptical galaxies. Recently,
however, Fermi/LAT detected γ-rays from a few narrow-line
Seyfert 1 galaxies and thus confirmed the presence of relativistic
jets in them. Since NLS1 galaxies are assumed to be young evolving
AGN, they offer a unique opportunity to study the production of
relativistic jets in late-type galaxies.
Our aim is to estimate by which processes the emission of various
kinds is produced in NLS1 galaxies and to study how emission
properties are connected to other intrinsic AGN properties.
We have compiled the so far largest multiwavelength database of NLS1
sources. This allowed us to explore correlations between different
wavebands and source properties using, for example, Pearson and
Spearman correlations and principal component analysis. We did this
separately for radio-loud and radio-quiet sources.
