Identikit

Joshua E. Barnes & John E. Hibbard

Identikit is a numerical method, combining test-particle and self-consistent techniques, which allows a rapid exploration of the parameter space of galactic encounters. It can be used to find the parameters required to reproduce the observed morphology and kinematics of interacting disk galaxies.

Identikit model (points) matching a self-consistent N-body simulation of a galactic collision (grey scale). Each panel shows a different projection: top left shows sky-plane (X,Y), top right shows velocity-position (V, Y); bottom left shows position-velocity (X, V), bottom right shows (X, Z).
