| What controls the FeII strength in active galactic nuclei? (2009) | |||||||||
Abstract | |||||||||
| We have investigated the correlations of the equivalent widths (EWs) of narrow and broad FeII emission lines and the FeII/MgII intensity ratio with fundamental physical parameters of active galactic nuclei (AGNs), luminosity (L), black hole mass (M_{BH}) and Eddington ratio (L/Ledd), using a homogenous sample of z | |||||||||
