摘要：We have studied the physical properties of a sample of narrow-line Seyfert 1 (NLS1) galaxies, and present a summary of our previous results, and new results. In particular, we have previously shown that (1) the locus of NLS1 galaxies on the MBH-s[OIII] plane does follow the relation of non-active galaxies after removing objects obviously dominated by outflows as evidenced by their [OIII] core blueshifts. We have (2) identified a number of so-called ’blue outliers’ with large outflow velocities revealed by their emission-line kinematic shifts. We also (3) present new correlations and trends which link black hole mass, Eddington ratio and physical parameters of the emission-line regions.
