Radial profiles of three different microhalos of models A (black) and B (blue) at z = 31. Four panels show the density, velocity dispersion, phase-space density, and accumulated mass. Circles show profiles of a low-resolution simulation (A512: 512 ³ particles, 1.0 × 10 ⁻⁴ pc softening length). Two out of three profiles (middle and bottom) are vertically shifted downward by 1 and 2 dex. In the panel of phase-space density profiles, the two profiles (middle and bottom) are shifted by 2 and 4 dex.
