| dc.description | Models of superdense star clusters at the center of galaxies are investigated to see whether such objects can be stable and long-lived based on evaporation and collision time-scales and stability criteria. We find that physically reasonable models of massive clusters of stellar remnants can exist with masses $\geq 10^6 M_{\odot}$, which could simulate black holes at the center of galaxies with large $M/L$ ratios and gas motions of order $\geq 10^3$ km $s^{-1}$. It follows that the evidence is not conclusive for massive dark objects at the center of galaxies being black holes. | |
