Intra-cluster Globular Clusters in a Simulated Galaxy Cluster [link]Paper  abstract   bibtex   
Using a cosmological dark matter simulation of a galaxy-cluster halo, we follow the temporal evolution of its globular cluster population. To mimic the red and blue globular cluster populations, we select at high redshift \$(z{\textbackslash}sim 1)\$ two sets of particles from individual galactic halos constrained by the fact that, at redshift \$z=0\$, they have density profiles similar to observed ones. At redshift \$z=0\$, approximately 60\textbackslash% of our selected globular clusters were removed from their original halos building up the intra-cluster globular cluster population, while the remaining 40\textbackslash% are still gravitationally bound to their original galactic halos. Since the blue population is more extended than the red one, the intra-cluster globular cluster population is dominated by blue globular clusters, with a relative fraction that grows from 60\textbackslash% at redshift \$z=0\$ up to 83\textbackslash% for redshift \$z{\textbackslash}sim 2\$. In agreement with observational results for the Virgo galaxy cluster, the blue intra-cluster globular cluster population is more spatially extended than the red one, pointing to a tidally disrupted origin.
