摘要：
Momentum feedback from super-Eddington accretion offers a simple explanation for the observed M-sigma and M-M-spher relations between supermassive black holes and the spheroids of their host galaxies. Recently Ferrarese et al. and Wehner & Harris observed analogous relations between the masses of central star clusters and their hosts. We show that stellar winds and supernovae from such nuclear clusters give similar feedback explanations for this case also, and we discuss the connection to the Faber-Jackson relation for the spheroids themselves.
