Median comoving matter density profile of haloes with bound masses, 9 · 10¹² h⁻¹ M_⊙ and 3 · 10¹³ h⁻¹ M_⊙. For each redshift, we separate the total profile, in grey, into three components: the bound population, in magenta, the unbound population, in green, and particles outside the potential well, in blue. For each line colour, higher redshifts are marked by darker colours. The dotted pink lines represent the best fit Diemer (2023) model B profiles to the bound population.
