Top panels: Stacked radial density profiles for a sample of 40 halos identified as the same in both the ΛCDM simulation (black-blue lines) and the covariantised dark Thomson-like interacting model simulation (red-orange lines). We show the total (solid lines), dark matter (dashed lines), and baryonic (dotted lines) density profiles. Bottom panels: Ratio between the dark matter and baryon density profiles for the ΛCDM (black lines) and the covariantised dark Thomson-like interacting model (red lines) simulations versus the reference ratio Ω_dm/Ω_b (dashed green line). We show the results for two different halo masses with reference to the non-interacting case: M_halo ∼ 10¹⁵ M_⊙/h (left panel) and M_halo ∼ 10¹⁴ M_⊙/h (right panel). Since we started from the same initial conditions, we identify each halo by its formation at the same spatial position and similar mass range, taking into account that the covariantised dark Thomson-like scattering produces less massive halos.
