"Matching models to merging galaxies: lost and found in parameter space"


Galactic collisions provide an elegant explanation for peculiar
galaxies, but very few collisions have been dynamically modeled.
I describe a new approach to navigating the parameter space of
galactic collisions and finding initial conditions which repro-
duce the observed morphology and kinematics of peculiar galaxies.
The method is tested on a randomly-generated sample of galactic
collisions; in many cases it accurately recovers the initial
conditions of these encounters.
