{{cite book}}: ISBN / Date incompatibility (help)A possible explanation is that both large black-hole masses and large globular cluster populations are associated with recent major mergers.
Verification of the picture above came from extremely precise HST/ACS imaging observations of NGC 2808 by Piotto et al. (2007), who resolve three main sequences in the cluster for a single turnoff (see figure 3). This remarkable observation is consistent with multiple stellar populations of approximately the same age with varying helium abundances
