From Supermassive Black Holes to Dwarf Elliptical Nuclei: A Mass Continuum

Considerable evidence suggests that supermassive black holes reside at the centers of massive galactic bulges. At a lower galactic mass range, many dwarf galaxies contain extremely compact nuclei that structurally resemble massive globular clusters. We show that both these types of central massive objects (CMOs) define a single unbroken relation between CMO mass and the luminosity of their host galaxy spheroid. Equivalently, MCMO is directly …
