Super-massive binary black hole and polarization in the broad lines
A number of active galactic nuclei (AGNs) show complex broad lines (with double peaks, highly shifted to the blue or red, and with a strong asymmetry). Some of these AGNs are established as super-massive binary black hole (SMBBH) candidates. Here we explore the characteristics of polarization in broad emission lines in the case that in the center of an AGN is located a SMBBH system. We used the 3D Monte Carlo radiative transfer code STOKES (Goosmann et al. 2013) for investigating polarized broad line emission, and we perform models for different parameters of SMBH system.
