Herschel/PACS spectroscopy of NGC 4418 and Arp 220: H2O, (H2O)-O-18, OH, (OH)-O-18, OI, HCN, and NH3

Full range Herschel/PACS spectroscopy of the (ultra)luminous infrared galaxies NGC 4418 and Arp 220, observed as part of the SHINING key programme, reveals high excitation in H 2O, OH, HCN, and NH 3. In NGC 4418, absorption lines were detected with E lower > 800 K (H 2O), 600 K (OH), 1075 K (...
