We propose to observe with XMM (120 ks) and HST (2 orbits) the luminous quasar HE 0238-1904 (z=0.63) hosting one of the best studied UV outflows to date. The inferred mass outflow rate and kinetic luminosity are typical of AGN where intense feedback is at work. HE 0238-1904 was detected in the XMM Slew Survey but no X-ray spectrum of this exceptional object has ever been acquired with any major X-ray observatory. Our aim is to obtain for the first time high-quality X-ray data of HE 0238-1904 in order to understand the physical properties of its innermost regions in terms of obscuration intrinsic spectral shape and possible presence of an X-ray counterpart to the UV wind. This observation will shed new light on the link between efficient accretion powerful winds and AGN feedback. [truncated! Please see actual data for full text]
