Halo and stellar mass measurements for a subsample of our UDGs with N_GC > 3. Top: distribution of the halo mass for the 27 out of the 74 UDGs with N_GC > 3 (grey) and 6 out of the 27 UDGs with N_GC > 3 and S_N > 30 (orange). The UDGs with high S_N are found to have a range of halo masses, with some at the high end of the distribution. Bottom: same as above but showing the distributions of halo-to-stellar mass ratios. The stellar masses are from Habas et al. (2020). The UDGs with the largest S_N values are all found to have a halo-to-stellar mass ratios above ∼500.
