N2  - The research presented in this thesis aims at improving the characterization of the scaling relations of
the masses of central Supermassive Black Holes with bulge and total luminosities of their host galaxies.
These scaling relations are significant for our understanding of the evolution of galaxies and the origins
of Supermassive Black Holes. As part of this investigation, 35 galaxies with known central Black Hole
mass were observed at near-infrared wavelengths. The obtained images were subjected to a thorough
photometric analysis, which led to reliable bulge and total luminosities. As a result, it could be shown
that the slope of the correlation between central Black Hole masses and bulge luminosities was previously
overestimated. Further, it was found that the correlation with total luminosity is equally tight as the
correlation with bulge luminosity. A linear regression method was devolped that enables extraction of
more detailed information about the cosmic scatter in the scaling relations. In the last part of this thesis,
a Black Hole mass was determined by means of dynamical modeling. The measured mass far exceeds
the prediction from current scaling relations, thereby putting the universality of the scaling relations in
question and principally opening up opportunities to better understand the physics of galaxy and Black
Hole formation.
