[70.10] A 3D Treatment of Radiative Transfer: Including Multi-wavelength Scattering; Absorption and Far Infrared Emission; and Arbitrary Geometry

M. Trewhella, B.F. Madore, L.E. Kuchinski (IPAC, Caltech/JPL)

We have developed a new model that uses a cellular approach to calculate radiative transfer of starlight through dusty media. The model is designed to be user friendly enough to be distributed as a tool for use by the general astronomical community. Its features include treatment of scattering, absorption and far infrared emission; propagating many wavelengths simultaneously; giving 26 views of the output from different directions; and the ability to cope with arbitrary geometry.

As an example of the model's use, we have simulated the propagation of starlight through the edge-on galaxy NGC~891. As well as recovering the familiar edge-on view, we have a prediction for what the galaxy may look like if seen at other viewing angles.
