REGIONAL VARIATIONS IN THE DENSE GAS HEATING AND COOLING IN M51 FROM<i>HERSCHEL</i>FAR-INFRARED SPECTROSCOPY
We present Herschel PACS and SPIRE spectroscopy of the most important far-infrared cooling lines in M51, [C ii](158 μm), [N ii](122 and 205 μm), [O i](63 and 145 μm), and [O iii](88 μm). We compare the observed flux of these lines with the predicted flux from a photon-dominated region model …
