Abstract
The detection of gravitationally redshifted optical emission lines has been reported just for a few active galaxies In this paper we give a short overview of studies that analyzed or exploited the detection of the gravitational redshift in optical AGN spectra In addition we tested the consistency of gravitational redshift as the physical origin of the redward shifts observed in their spectra using a sample of approx50 HamburgESO intermediate to high redshift quasars that are among the most luminous quasars known 1047 lesssim L lesssim 1048~mboxerg/s and are expected to host very massive black holes To this aim we modeled the line profile with accretion disk models around a black hole
