This is known as the M-sigma relation, which has been observed in multiple studies. It suggests that there is a correlation between the mass of the supermassive black hole at the center of a galaxy and the velocity dispersion of stars in the bulge of the galaxy, which is related to the size of the bulge. Therefore, galaxies with larger central bulges tend to have larger black hole masses at their centers.
