摘要：
We study the Fell properties of double-peaked broad low-ionization emission line AGN (dbp emitters) using a sample of 27 dbp emitters from SDSS (DR4). Our first result is that the line spectra in the wavelength range from 4100 angstrom to 5800 angstrom can be best fitted by an elliptical accretion disk model. The best fitted results indicate that the optical Fell emission lines of dbp emitters originate from the same region in the accretion disk where the double-peaked Balmer emission lines originate. Some correlations between Fell emission lines and the other broad emission lines for normal AGN can be confirmed for dbp emitters. However,. these results should be taken with caution due to the small number of objects and the bias in selecting strong Fell emitters. We show that for dbp emitters, BH masses seems to have more influence on Fell properties than dimensionless accretion rate.
