Top: total host halo mass, , distribution of host halos in which at least one DMC DG (green) is embedded is shown in green and in which at least one TDGC of sample A is embedded is shown in red for redshift z = 0. Bottom: distribution of the number of TDGCs (sample A) per host halo at redshift z = 0. The histogram is fitted with an exponential function (solid green line) given by Eq. (7). The fitting parameters are listed in the text. The histograms have a bin width of .
