Figure 4. Fits to rest-frame photometry for individual GDDS galaxies. A hot greybody + PAH model (the dashed blue line) is seen to do an excellent job of boosting the flux from starlight at rest wavelengths around 3 μm in order to fit the data. Mentuch et al. (2009) shows how such a model is consistent with emission from a hot circumstellar torus around massive young stars. 11 GeminiFocus June2012
