Detecting the intrinsic Baldwin Effect of the optical Fell complex in Luminous Seyfert 1 Galaxy Fairall 9

摘要：

We analyze the optical spectra of Fairall 9, a luminous Seyfert 1 galaxy. They are obtained from the AGN Watch program that has monitored this object for 9 months. The flux and variation of the optical Fell complex is measured using multi-component profile modeling with Fell templates. A convincing intrinsic Baldwin Effect (BEff) of optical Fell emission blends in Fairall 9 is discovered for the first time. The variation of FeII/Hβ (RFe) in Fairall 9 is obtained. We also detect a marginal anti-correlation between RFe and the continuum flux in its spectra. This anti-correlation and the relatively broad profile of Hβ in this galaxy support the dichotomy reported by Wang et al. (2005).
