🌀 Galaxy Merger Lab: Mass Ratio, Orbit and Tidal Tails

A Toomre-style restricted N-body lab for galaxy encounters: choose mass ratio (1:1 to 1:10), pericentre, eccentricity and disc spin direction, and watch tidal tails, bridges, shells and the merger remnant form. Live graphs track separation, remnant ellipticity and a gas-compression star-formation proxy, plus a toy black-hole pair merger timeline.
