On the nature of type 1 AGN: emission properties and correlations
[摘要] We present a study of emission properties and correlations of 3191 type 1 AGN at z Edd). Objects with higher L/LEddtend to have narrower broad Hβ component, strong Ee II emission, systematic blueshift of C IV λ1549, soft X-ray excess, and lower ionization parameter compared to those of the lower L/LEdd.
