Scientific paper

The first Herschel observations of OH absorption in ULIRGs are revealing P-Cygni profiles indicative of massive molecular outflows suggestive of AGN feedback. We present the early observations of these outflows and the estimated ranges of gas mass, dynamical timescale, mechanical power, mass loss rate, and kinematic energy as well as arguments that radiation pressure may drive them. Our estimates of the outflow parameters will improve when observations of excited rotational levels are obtained.
