Simulated X-ray surface brightness (0.5 − 8 keV), X-ray-weighted temperature, LOS velocity dispersion, and bulk velocity for simulations with (ξ₀,  P₀) = (10,  2.5 Mpc) and (5,  2.5 Mpc) at t = 5.0 and 3.2 Gyr, viewed at inclination angles i ≃ 40°, respectively. Black contours in the left panels mark the total mass distribution. The models in the top and bottom panels resemble the subcluster perturbers associated with IC310 and NGC1264, which drive the inner sloshing spiral in Perseus, respectively. Both simulations reproduce the asymmetric dipole-like structure in the bulk velocity (see Sect. 5).
