Searches for supermassive black holes in galaxy centers, conducted with HST and other telescopes, have led to the discoveries that {1} most or all hot galaxies contain massive dark objects at their centers, presumably black holes; {2} there is a remarkably tight correlation between the black-hole mass and the luminosity-weighted velocity dispersion of the hot component of the galaxy. This mbh-Sigma relation has a scatter which is <0.3 dex in mbh and consistent with zero. This relationship suggests a strong link between black-hole formation, AGN activity, and galaxy formation, and once it is understood this link should advance our understanding of all three processes. The goal of this proposal is to investigate the scatter in the mbh-Sigma relation and the role of possible second parameters, by examining a sample of galaxies at fixed velocity dispersion Sigma=200+/- 20 kms. This approach decouples the effects of a second parameter from uncertainties in the shape of the mbh-Sigma relation, and minimizes spurious correlations because all of the galaxies will be studied using the same well-tested observational and modeling techniques. The sample is chosen to explore second parameters such as environment, X-ray properties, Hubble type, luminosity profile, etc. This work thus treads a path similar to the one that took us from simple bivariate relationships among galaxy properties to the deeper concept of a fundamental plane of galaxies.
