Host Galaxies and Environment of Narrow Line Seyfert 1 Nuclei
We compared the environment and host galaxies of “Narrow Line” Seyfert 1 with those of Sy1, Sy2, and non-active galaxies. We found that NLSyls are hosted in smaller galaxies than Sy1s. This result supports the idea of NLSy1s as Sy1s with higher Eddington ratio. NLSy1 hosts may be more isolated and farther away from bright companions than Sy2s and normal galaxies.
