Evolution of the satellites’ number count across cosmic time for all CosmoRun models analyzed in this paper. We count all satellite galaxies located within the host virial radius and the ‘splashback’ galaxies. Markers and lines represent the average number of satellites for each time bin. Top panel: Evolution of the total number of satellite galaxies for all models. Central and bottom panels: Evolution of the number of satellite galaxies with M_peak<10¹⁰ M_⊙ and M_peak>10¹⁰ M_⊙, respectively.
