Dection of [CII] emission not associated with star-forming material in giant molecular clouds
Abstract
Large scale maps of [C II] emission obtained with the Stratospheric Observatory For Infrared Astronomy (SOFIA) and the German REceiver for Astronomy at Terahertz Frequencies (GREAT) have revealed that a large fraction (>50%) of the spatial distribution of the [C II] emission is not associated (in velocity channel maps) with the emission observed in other atomic and molecular tracers. I will present the results found in M17SW and NGC3603, and compare the [C II] maps with data obtained with the IRAM 30m and APEX telescopes. I will also discuss the implications these results have for PDR modelling.
