<John Kormendy> investigates the structure of <galaxies> and their central <supermassive black holes>. His 2013 review with <Luis C. Ho> examines <black hole> <mass> measurements inferred from spatially resolved <motion> and their correlations with different components of the host <galaxy>.
An important distinction is between a <galactic bulge>, a <galactic disk> and a <pseudobulge>: the authors find that the same simple coevolution story does not describe all three. A correlation such as the <M-sigma relation> is therefore evidence to interpret in its structural context, rather than a universal description of every <galaxy>.<Coevolution (Or Not) of Supermassive Black Holes and Host Galaxies by John Kormendy and Luis C.
