摘要：

The broad emission lines (BELs) in spectra of type 1 Active Galactic Nuclei (AGN) can be very complex, indicating a complex broad line region (BLR) geometry According to the standard unification model one can expect an accretion disk around a supermassive black hole in all AGN. Therefore, a disk geometry is expected in the BLR. However, a small friction of BELs show double-peaked profiles which indicate the disk geometry. Here, we discuss a two-component model. assuming an emission from the accretion disk and one additional emission from surrounding region. We compared the modeled BELs with observed ones (mostly broad H alpha and H beta profiles) finding that the model can well describe single-peaked and double-peaked observed broad line profiles.
