The ionization of PAH, by ultraviolet UV photons from massive stars is expected to account for a large fraction of the heating of neutral gas in galaxies.
Emission maps of gas cooling Emission maps of gas cooling. Maps on the upper row show the [C ii] line at 158 µm, as well as the [O i] lines at 145 µm and 63 µm, which were observed with Herschel-PA… [+2604 chars]
