We present KAO 60-micron, CSO SHARC II 350-micron and JCMT 450 and 850-micron data of the colliding galaxies NGC 4038/39 ("The Antennae"). These far-infrared and submillimeter data are the most complete set to date which fully sample the spectral energy distribution of the large grain dust component in this object. With a resolution of 17 arcseconds or better, they also represent the highest resolution data available at these wavelengths.

Using these data, we construct maps which compare the distribution of large grains to the distributions of PAHs and very small grains imaged by ISOCAM. We also map the variation in temperature of the large grains, and investigate how this correlates with the burst of star formation which has been inferred in this colliding system.
