Exploring NLS1 through the physical properties of their hosts

Abstract

In this work we aim at addressing the still open question about the nature of Narrow-Line Seyfert 1 (NLS1) galaxies: are they really active nuclei with lower mass Black-Holes (BHs) than Seyfert 1 (S1) and quasars? Our approach is based on the recently discovered physical connections between nuclear supermassive BHs and their hosting spheroids (spiral bulges or ellipticals). In particular we compare BH masses of NLS1s and S1s analyzing the properties of their hosts by means of spectroscopic and photometric data in the optical wavelength domain. We find that NLS1s fill the low BH mass and bulge luminosity values of the BH mass - bulge magnitude relation, a result strongly suggesting that NLS1s are active nuclei where less massive BHs are hosted by less massive bulges. The correlation is good with a relatively small scatter fitting simultaneously NLS1s, S1s and quasars. On the other hand, NLS1s seem to share the same stellar velocity dispersion range of S1s in the BH mass - stellar velocity dispersion relation, indicating that NLS1s have a smaller BH/bulge mass ratio than S1s. These two conflicting results support in any case the idea that NLS1s could be young S1s. Finally we do not confirm the significantly non linear BH--bulge relation claimed by some authors.
