Scientific paper

XMM-Newton and Chandra observations of quasars suggest the presence of high-velocity outfiows of ionized absorbing material with mass-outflow rates of up to a few Msolar yr-1 that are considerably higher than those based on the wind properties derived from UV BALs. Quasar winds might be more powerful than what we previously thought. X-ray absorption lines produced by outfiowing material detected in several quasars are possibly probing a highly ionized and high velocity component of the accretion disk wind that appears to be distinct from the absorbers detected in the optical and UV wavebands. We present X-ray absorption line diagnostics that allow us to constraint the properties of the outfiowing wind in quasars.
