The m-sigma relation is a correlation between the mass of a supermassive black hole and the velocity dispersion of stars in the bulge of its host galaxy. This relationship indicates that as the mass of the black hole increases, the velocity dispersion of stars also increases, suggesting a co-evolution between supermassive black holes and their host galaxies. It is significant for understanding how black holes influence galaxy formation and dynamics.
congrats on reading the definition of m-sigma relation. now let's actually learn it.
