The shifts are measured as a difference between the centroids at 5% and 95% of the Hβ and Mg II broad line intensities. Obtained masses have been compared with ones estimated from wide accepted virial method (using widths of Hβ and Mg II broad lines). We discuss the possibility to use the gravitational redshift for black hole mass estimations in AGN and validity of virialization assumption in the AGN broad lines. |
