Herschel FIR & submm photometry of KINGFISH sample

The spatially integrated fluxes are largely consistent with expectations based on Spitzer far-infrared photometry and extrapolations to longer wavelengths using popular dust emission models. Dwarf irregular galaxies are notable exceptions, as already noted by other authors, as their 500{mu}m emission shows evidence for a submillimeter excess.

In addition, the fraction of dust heating attributed to intense radiation fields associated with photodissociation regions is found to be (21+/-4)% larger when Herschel data are included in the analysis. Dust masses obtained from the dust emission models of Draine & Li (2007ApJ...657..810D) are found to be on average nearly a factor of two higher than those based on single-temperature modified blackbodies, as single blackbody curves do not capture the full range of dust temperatures inherent to any galaxy.
