Moreover, it is revealed that barred galaxies (with their relatively small, faint, and low stellar concentration bulges) can deviate from the M-sigma relation by delta(log M) = -0.5 to -1.0 dex (in the sense that their sigma values are too large) and generate much of the aforementioned correlations. Removal of the seven barred galaxies from the Tremaine et al.
