Query: Relation Between Globular Clusters and Supermassive Black Holes in
  Ellipticals as a Manifestation of the Black Hole Fundamental Plane   We analyze the relation between the mass of the central supermassive black
hole (Mbh) and the number of globular clusters (Ngc) in elliptical galaxies and
bulges as a ramification of the black hole fundamental plane, the theoretically
predicted and observed multi-variable correlation between Mbh and bulge binding
energy. Although the tightness of the Mbh-Ngc correlation suggests an unlikely
causal link between supermassive black holes and globular clusters, such a
correspondence can exhibit small scatter even if the physical relationship is
indirect. We show that the relatively small scatter of the Mbh-Ngc relation
owes to the mutual residual correlation of Mbh and Ngc with stellar mass when
the velocity dispersion is held fixed. Thus, present observations lend evidence
for feedback-regulated models in which the bulge binding energy is most
important; they do not necessarily imply any `special' connection between
globular clusters and Mbh. This raises the question of why Ngc traces the
formation of ellipticals and bulges sufficiently well to be correlated with
binding energy.
