Description An exciting result of the first year of Herschel was the detection of massive molecular outflows (traced mainly by the OH molecule) in luminous dusty AGN, possibly providing the smoking gun of AGN feedback that is key to many models of galaxy evolution. All Herschel molecular outflow detections up to now are in luminous and distant systems (ULIRGs) or in nearby starbursts (NGC 253), while none of the nearbyt Seyferts observed so far showed clear outflow signatures, neither in Herschel spectra nor in ground based mm observations. Very recently, using IRAM PdBI, we have detected a massive molecular outflow in the nearby AGN NGC3079, via P-Cygni profiles of the HCN and HCO+ lines. By its proximity, this system could be a unique testbed for a spatially resolved Herschel study of such outflows, providing essential help in the interpretation of already ongoing GT and OT1 observations of more distant sources as well as stimulating and influencing further OT2 studies. Therefore, we suggest a DDT programme here, to observe several OH transitions of 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.
