Key gas properties around dark matter particles in projected spatial coordinates. The upper panels illustrate the spatially projected distribution of dark matter particles in the (x, y) coordinates, and the lower panels depict the distribution in the (x, z) coordinates. The colors indicate the mean values of the weighted (from left to right) relative velocity between the DM particle and the neighboring gas particles, the sound speed in the medium, and the mean molecular weight. The particle distribution is centered on a halo with M_vir = 4.6 × 10⁶ M_⊙, T_vir = 8768 K, and r_vir = 0.2 kpc, highlighted by cyan circles in each panel.
