Galaxies: Spiral Arms, Cooling Lines

Scientific paper

We present a detailed study of photon dominated regions at several spiral arm positions and the centers of the nearby spiral galaxies M51 and M83. For this, we combine all important cooling lines: [CI] 609μm taken at the JCMT with 12CO and 13CO 1-0 and 2-1 lines taken at the IRAM 30m MRT. These transitions are combined with data taken from the literature: ISO/LWS [CII] 158μm, [OI] 63μm, 146μm, and [NII] (122μm) data (Brauher, J., et al. 2004) and mid-J CO lines from (Bayet, E., et al., Dumke, M., et al. 2003, Israel, F., Baas, F., 2002).
