We present the black hole mass–bulge velocity dispersion relation for a complete sample of 75 soft X-ray selected AGNs. We find that the AGNs with highest accretion rates relative to Eddington lie below the MBH–σ relation of broad line Seyfert 1s, confirming the Mathur et al. (2001) result. The statistical result is robust and not due to any systematic measurement error. This has important consequences towards our understanding of black hole formation and growth: black holes grow by accretion… 
Star Captures by Quasar Accretion Disks: A Possible Explanation of the M-σ Relation
A new theory of quasars is presented in which the matter of thin accretion disks around black holes is supplied by stars that plunge through the disk. Stars in the central part of the host galaxy are
A Complete Sample of Soft X-Ray-selected AGNs. II. Statistical Analysis*
Direct correlations and a principal component analysis (PCA) are presented for a complete sample of 110 soft X-ray–selected AGNs, of which about half are narrow-line Seyfert 1 galaxies (NLS1's). The

A Complete Sample of Soft X-Ray-selected AGNs. I. The Data*
We present the optical spectra and simple statistical analysis for a complete sample of 110 soft X-ray?selected AGNs. About half of the sources are narrow-line Seyfert 1 galaxies (NLS1's), which have
