Abstract:
Dust grains absorb the interstellar far ultra-violet and visible
photons and re-emit them in far-infrared (FIR) wavebands. The dust FIR
continuum can be predicted by a grid of models using various values of
the interstellar radiation field.
We analyze the dust continuum emission in two Hi-GAL
science-demonstration phase (SDP) fields using both the radiative
transfer code, Cloudy, and the DustEM dust model, to explore the
effect of radiative transfer on dust temperature. The 500um
sub-millimeter excess emission and the very small grain (VSG)
contribution to the 70um intensity are investigated by spectral energy
distribution (SED) fitting using the Cloudy model.
