Reconstructing Galaxy Collisions: an Ensemble Approach.

Collisions are major chapters, and often defining events, in a
galaxy’s history. By reconstructing the ongoing collisions we
observe among nearby galaxies, we gain insight into galaxy
evolution. But observations don’t provide enough information for
unique reconstructions: We can only observe three of the six
phase-space coordinates of the luminous material, and use that to
constrain the distribution of dark matter. Our best option is to
identify an /ensemble/ of models, all matching the observations of a
particular system. I will describe an algorithm which is capable of
generating such ensembles. Refining, testing, and evaluating model
ensembles may be a suitable project for large-scale computing.
