Far-Infrared emission from dust in gas-rich galaxies — •Cristina C. Popescu and Richard J. Tuffs — Max Planck Institut fuer Kernphysik, Astrophysics Department, Saupfercheckweg 1, 69117 Heidelberg

Following on from IRAS, the ISOPHOT instrument on board the Infrared Space Observatory (ISO) and now the MIPS instrument on board the Spitzer Space Observatory are providing a huge advancement in our knowledge of the phenomenology of the far-infrared (FIR) emission of gas-rich galaxies and the underlying physical processes. Here we review the main observational characteristics of dust emission in galaxies and how these can be understood and quantitatively explained through modelling.
