🌀 Galaxy Collision (Toomre Restricted Three-Body): 2D Top View

Interactive 2D top and side view of two colliding disk galaxies in the Toomre and Toomre restricted three-body model: thousands of massless stars orbit two softened cores that follow a Keplerian encounter with halo dynamical friction, producing tidal tails, bridges and mergers you can aim by dragging the start position and velocity.
