We report two new XMM–Newton observations of PG1211+143 in 2007 December, again finding evidence for the fast outflow of highly ionized gas first detected in 2001. Stacking the new spectra with those from two earlier XMM–Newton observations reveals strong and broad emission lines of Fe xxv and O viii, indicating the fast outflow to be persistent and to have a large covering factor. This finding confirms a high mass rate for the ionized outflow in PG1211+143 and provides the first direct measurement of a wide angle, subrelativistic outflow from an active galactic nuclei (AGN) transporting mechanical energy with the potential to disrupt the growth of the host galaxy. We suggest PG1211+143 may be typical of an AGN in a rapid super-Eddington growth phase.
