The Arkansas Galaxy Evolution Survey is conducting a census of supermassive black hole (SMBH) masses over cosmological epochs, as a contribution to understanding the role played by these objects in the evolution of galactic structure. Presently there are three main projects within the collaboration. The first aims to make use of a relation, newly discovered by the collaboration, between SMBH mass and spiral arm pitch angle in disc galaxies, as a tool to estimate the masses of SMBHs in quiescent galaxies out to redshifts of z=1. The second aims to search for binary SMBHs in ultra luminous infrared galaxies by looking for evidence of binarity in X-ray images of their galactic nuclei. The third will look for evidence of SMBH mass evolution over the peak of quasar luminosity evolution from z=2 to z=4. We briefly describe the three projects, and discuss how they will contribute to a deeper understanding of the role of SMBHs in the evolution of galactic structure.
