| Description | An exciting result of the first year of Herschel was the detection ofmassive molecular outflows (traced mainly by the OH molecule) in luminous dusty AGN, possibly providing the smoking gun of AGNfeedback that is key to many models of galaxy evolution. All Herschelmolecular outflow detections up to now are in luminous and distantsystems (ULIRGs) or in nearby starbursts (NGC 253), while none ofthe nearbyt Seyferts observed so far showed clear outflow signatures, neither in Herschel spectra nor in ground based mmobservations. Very recently, using IRAM PdBI, we have detected a massive molecular outflow in the nearby AGN NGC3079, via P-Cygniprofiles of the HCN and HCO+ lines. By its proximity, this systemcould be a unique testbed for a spatially resolved Herschel studyof such outflows, providing essential help in the interpretation ofalready ongoing GT and OT1 observations of more distant sourcesas well as stimulating and influencing further OT2 studies. Therefore,we suggest a DDT programme here, to observe several OH transitionsof different energy level with PACS. The observations are tuned to deliver simultaneously, i.e. at no additional costs, lines of HCN, CO,and CII/ |

| Mission Description | Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
