Query: Scalable N-body code for the modelling of early-type galaxies   Early-type galaxies exhibit a wealth of photometric and dynamical structures.
These signatures are fossil records of their formation and evolution processes.
In order to examine these structures in detail, we build models aimed at
reproducing the observed photometry and kinematics. The developed method is a
generalization of the one introduced by Syer and Tremaine (1996), consisting in
an N-body representation, in which the weights of the particles are changing
with time. Our code is adapted for integral-field spectroscopic data, and is
able to reproduce the photometric as well as stellar kinematic data of observed
galaxies. We apply this technique on SAURON data of early-type galaxies, and
present preliminary results on NGC 3377.
