"Narrow Line Seyfert Is - AGN that don't fit the model"

ABSTRACT: "Narrow Line Seyfert 1s are unusual in that they show many of the properties of Sy 1 galaxies, except that they have narrow permitted optical lines. They also show large amplitude, rapid variability in their extremely soft X-Ray spectra. It seems difficult to reconcile NLS1 galaxies with current orientation based unification models. The various NLS1 models will be discussed, along with recent results from our multi wavelength observing campaign and my work at the JAC."
