Comparison of hydrogen number density profiles nH(r) within DM halos of different masses (Mh = 104 M⊙, 106 M⊙, and 108 M⊙) at redshifts z = 6 (solid lines), z = 10 (dashed-dotted lines), and z = 40 (dotted lines). The three density profiles examined include a simple isothermal profile (magenta), the profile derived by Makino et al. (1998) (blue), and the rescaled profile from Liu et al. (2022) (green). The vertical grey lines denote the virial radii of the corresponding halos at each redshift.
