Scientific paper

We present the relation between spiral arm pitch angle (a measure of how tightly wound spiral arms are in disk galaxies) and supermassive black hole (SMBH) mass, and use this relation to estimate SMBH masses in galaxies out to z 1.3. We show that the average SMBH mass in disk galaxies has grown significantly since z 0.3, but there seems to be little evolution at earlier times. We present plausible explanations as to why such evolution might be expected for SMBHs in disk galaxies.
