Global simulation of a full accretion disk impacted by an EMRI. The color scale shows the absolute velocity perturbation ∣Δv∣/c relative to the unperturbed disk. Regions outside of the Hill sphere remain essentially unaffected by the intruder. The white box outlines the simulation domain we adopted in our production runs. This sector has a radial width of ∼0.2 au, and spans an azimuthal angle corresponding to ∼1/16 of the local disk circumference, centered on the impact point. The upper-right panel displays a magnified view of the stellar EMRI resolved by ∼10⁵ MFM particles in our simulations.
