Talk Title: Rogue NLS1 - An AGN story
Abstract: Although more than 30 years have passed since their discovery, narrow-line Seyfert 1 galaxies (NLS1s) still present challenges for unified models of active galactic nuclei (AGN). Sources of electromagnetic emission at all frequencies, their physical properties and role in galaxy evolution remain poorly understood. In this seminar I will outline their most relevant characteristics, and I will present the two current main hypotheses about their physical nature. I will also highlight the results of a recent NLS1s JVLA radio survey, the largest carried out so far, and of recent studies about their host galaxy morphology, showing how they impact on our understanding of this interesting class of AGN.
