| Description | Simulations of structure formation and evolution suggest that feedback is critically important to the evolutionary paths of galaxies and their supermassive black holes. However, while high velocity outflows have been routinely detected in the ionized winds of many powerful AGN, it remained unclear whether this momentum was being effectively transferred to the neutral and molecular gas that actually form stars. Several recent observations over the past year have finally provided some breakthroughs in this regard: in particular the neutral NaD and molecular OH and CO components in the warm quasar-dominated merger Mrk 231 have all been shown to have >1000 km/s outflows from the nucleus, indicating momentum transfer well in excess of what could be produced by the ongoing star formation alone. Several more ULIRGs are under similar investigation to broaden these important results and understand how this feedback might scale with relative AGN strength, merger stage, availability of fuel, etc. Somewhat surprisingly, these samples include none of the most powerful (i.e., ..hyper.) luminous infrared galaxies (HLIRGs). ..Local. HLIRGs are 3-10x more powerful than Mrk 231 and their bolometric output is almost always AGN-dominated. As such, HLIRGs can extend studies of how AGN power affects feedback by an order of magnitude. Here we propose to look for trends between the basic measured properties of OH (incidence of absorption, kinematics, column densities) and host/evolutionary indicators in a sample of 5 powerful HLIRGs. |

| 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. |
