Implications of Quasar Black Hole Masses at High Redshifts
Matthias Dietrich, Fred Hamann
We investigated a sample of 15 luminous high-redshift quasars (3.3 < z < 5.1) to measure the mass of their super-massive black holes (SMBH) and compare, for the first time, results…

The Black Hole-Bulge Relationship in QSOs
G. A. Shields, K. Gebhardt, S. Salviander +5
We use QSO emission-line widths to examine the black hole mass - sigma relationship as a function of redshift and to extend the relationship to larger masses. Supermassive black ho…
