On the nature of Seyfert galaxies with high [OIII]5007 blueshifts
S. Komossa, D. Xu, H. Zhou +2
We have studied the properties of Seyfert galaxies with high [OIII]5007 blueshifts (`blue outliers'), originally identified because of their strong deviation from the M_BH - sigma…

Narrow-line Seyfert 1 Galaxies and the M_BH - sigma Relation
S. Komossa, D. Xu
We have studied the location of narrow-line Seyfert 1 (NLS1) galaxies and broad-line Seyfert 1 (BLS1) galaxies on the M_BH - sigma relation of non-active galaxies. We find that NLS…

The narrow-line region of narrow-line and broad-line type 1 AGN I. A zone of avoidance in density
Dawei Xu, Stefanie Komossa, Hongyan Zhou +2
The properties of narrow-line Seyfert 1 (NLS1) galaxies, the links and correlations between them, and the physics behind them, are still not well understood. Apart from accretion r…
