Quasar Black Hole Mass Estimates from High-Ionization Lines: Breaking a Taboo?

Quasar Black Hole Mass Estimates from High-Ionization Lines: Breaking a Taboo?

Can high ionization lines such as CIV λ 1549 provide useful virial broadening estimators for computing the mass of the supermassive black holes that power the quasar phenomenon? The question has been dismissed by several workers as a rhetorical one because blue-shifted, non-virial emission assoc...
