Exploring the Powerful Ionised Wind in the Seyfert Galaxy PG1211+143

Highlyionised highspeed winds in AGN (UFOs) were first detected withXMMNewton a decade ago, and are now established as a key factor in the study ofSMBH accretion, and in the growth and metal enrichment of their host galaxies.However, information on the ionisation and dynamical structure, and the ultimatefate of UFOs remains very limited. We request a 600ks extended XMMNewton studyof the prototype UFO PG1211+143 in AO13, to obtain high quality EPIC and RGSspectra, to map the flow structure and variability, while seeking evidence forthe anticipated interaction with the ISM and possible conversion of theenergetic wind to a momentumdriven flow. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
