Abstract: (arXiv)
We report two new XMM-Newton observations of PG1211+143 in December 2007, finding further evidence of the fast outflow of highly ionised gas, first detected in 2001. Stacking the new spectra with those from two earlier XMM-Newton observations reveals a broad PCygni profile in the Fe K band, showing the fast outflow to have a large covering factor, and confirming its significance as a powerful feed of mechanical energy into the host galaxy.
