NMAGIC made-to-measure particle models of galaxies
  The parallel code NMAGIC is an implementation of a particle-based method to
create made-to-measure models in agreement with observations of galaxies. It
works by slowly correcting the particle weights of an evolving N-body system,
until a satisfactory compromise is achieved between the goodness of the fit to
a given set of observational data, and some degree of smoothness
(regularization) of the underlying particle model. We briefly describe the
method together with a new regularization scheme in phase-space, which improves
recovering the correct orbit structure in the models. We also mention some
practical applications showing the power of the technique in investigating the
dynamics of galaxies.
