Scientific paper

Globular clusters seem to be the best place to search for Intermediate Mass Black Holes (IMBHs) in the local universe, but so far no definitive observational evidence for their existence has been found. Here we evaluate the uniqueness of classical signatures from stellar dynamics that are typically associated to the presence of a central IMBH (shallow cusp in the surface brightness profile and central rise in the velocity dispersion). We also present a novel technique to identify likely IMBH hosts, based on the measurement of mass segregation in collisionally relaxed globular clusters.
