Line Shifts in the Two-Phase Broad-Line Region with Radial Kinematics1
Published online by Cambridge University Press: 12 April 2016
Abstract
We consider in detail the two-phase BLR model with radial infall kinematics. Numerical calculations show that Lyα and C IVλ1549 profiles are blueshifted from their systemic rest-frame velocity, and their profiles are in qualitative agreement with the observations. It seems that the observed velocity differences between the high and low-ionization lines in the spectra of quasars can be understood in such a simple, physical, self-consistent model.
