10. Cool dust heating and temperature mixing in nearby star-forming galaxies
Physical conditions of the interstellar medium in galaxies are closely linked to the ambient radiation field and the heating of dust grains. ... The KINGFISH profiles are well suited to examining trends of dust temperature Tdust and нІ because they span a factor of ~200 in the ISRF intensity heating the bulk of the dust mass, Umin. Results from fitting the profile SEDs suggest that, on average, Tdust, dust optical depth о„dust, and Umin decrease with radius. ...

We present spectral line images of [CI] 809 GHz, CO J=1-0 110 115 GHz and HI 1.4 GHz line emission along a ~1ТА region in the l=328ТА direction of the Galactic plane. The [CI] data comes from the High Elevation Antarctic Terahertz (HEAT) telescope, a new facility on the summit of the Antarctic plateau where the precipitable water vapour falls to the lowest values found on the surface of the Earth. ... The [C/CO] abundance ratio averaged through the filament is found to be approximately unity. ...
