Abstract

We investigate the cosmic evolution of the black hole (BH) mass -- bulge luminosity relation using a sample of 52 active galaxies at and in the BH mass range of . By consistently applying multi-component spectral and structural decomposition to high-quality Keck spectra and high-resolution HST images, BH masses () are estimated using the H broad emission line combined with the 5100 Å nuclear luminosity, and bulge luminosities () are derived from surface photometry. Comparing the resulting relation to local active galaxies and taking into account selection effects, we find evolution of the form with , consistent with BH growth preceding that of the host galaxies. Including an additional sample of 27 active galaxies with taken from the literature and measured in a consistent way, we obtain for the relation and for the --total host galaxy luminosity () relation. The results strengthen the findings from our previous studies and provide additional evidence for host-galaxy bulge growth being dominated by disk-to-bulge transformation via minor mergers and/or disk instabilities.
