Dust absorption
For modelings in the Infrared, dust properties need to be incorporated.
So far there is only limited work on this subject (Guiderdoni et al. 1998).
Difficult problems include chemical evolution of the dust and the geometrical
distribution of dust in a galaxy. Following some simple assumptions of
these properties, one can start by calculating the optical thickness of
the disk and therefore the extinction. The extinction gives the amount
of bolometric luminosities absorbed by dust and then re-radiated in the
infrared. It is yet to be clarified how galaxy-galaxy interactions, such as
merging, would modify these assumptions.
