Probing the matter flow in distant QSO with the aid of gravitational lensing

The M_SMBHsigma relation proved that the central blackhole and the hostinggalaxies coevolved across cosmic time. The Xray ultrafast outflows in nearbyAGN, are probably one of the ingredients that builtup the needed feedbackmechanism. At highz, however, they were measured only in few objects, mainlythanks to gravitational lenses. We thus propose to continue a program started inXMMNewton AO13, to point for 150 and 80 ks a couple of distant and lensed QSO:Q2237+030 and MG0414+0534. Our goal is to characterize their Xray spectrum andto detect blushifted absorption lines at E sim 79 keV and, possibly, blurredreflection component. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
