  The central regions of galaxies show the presence of super massive black
holes and/or very dense stellar clusters. Both objects seem to follow similar
host-galaxy correlations, suggesting that they are members of the same family
of Compact Massive Objects. We investigate here a huge data collection of
Compact Massive Objects properties to correlate them with absolute magnitude,
velocity dispersion and mass of their host galaxies.
