| Abstract: |
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. |
