Survival fractions f_sv = N_sv/N_initial of streams and remnant star clusters from cosmological simulations as a function of initial cluster mass. A system is considered to have survived if it satisfies L > 1000 kpc km s⁻¹ and meets specific criteria: survived streams must be visible at the present day, while survived clusters must maintain a remnant mass M_cluster > 500 M_⊙. The gray vertical band marks regions with no simulated clusters. The error bars show the Poisson error of a fraction.
