[CII] and [NII] in the Nucleus of IC342

University of Cologne
We present SOFIA/GREAT observations of [CII] 158 µm and [NII] 205µm emission from the nuclear region of the spiral IC 342. The [CII] and [NII] data will be used to characterize how much the different phases of the circum-nuclear ISM contributes relatively to the overall observed emission. Particularly the correlation between [NII], emitted from [HII] regions exclusively, and the [CII] emission line, coming both from PDRs and from the ionized gas, is studied taking advantage of the high spectral resolution of the [NII] and [CII] emission.
