| Abstract: |
IDENTIKIT was originally developed as a fast approximate scheme for
modeling the tidal morphology and kinematics of disk galaxy encounters
and mergers. In this form, it was first used to implement an
interactive modeling tool for galaxy collisions; tests with artificial
data showed that the morphology and kinematics of merging
galaxies strongly constrain their initial conditions. This tool is
now being applied to real galaxies. More recently, IDENTIKIT has been
used to develop a mapping from the present state of a tidal encounter
back to the initial conditions; this offers a way to partly automate
the search for dynamical models of galaxy encounters. Finally,
IDENTIKIT's theoretical applications include a comprehensive way to
evaluate the mass and extent of tidal features as functions of halo
structure. |
