Conducted simulations in r_h, τ_dyn parameter space. Contours indicate the number of simulation particles in the 10λ_cr × 5λ_cr runs when identical particles are used (see Eq. (16)). Thick red lines indicate surveys illustrated in Figs. 5 and 7 in Mondino-Llermanos & Salo (2023), while black lines indicate range of other surveys made. Shaded region (from Fig. 10 in Mondino-Llermanos & Salo 2023) indicates the regime where overstability is obtained in simulations with identical particles with ϵ_n = 0.1. Circles stand for size distribution runs with W = R_max/R_min = 20, q = 3, with filled circles indicating overstable cases. In experiments with W = 20, the number of particles is ~7 times larger than indicated by the contours (see Appendix A).
