The first X-ray view of the extreme UV outflow quasar HE0238-1904

We propose to observe with XMM (120 ks) and HST (2 orbits) the luminous quasarHE 02381904 (z0.63), hosting one of the best studied UV outflows to date. Theinferred mass outflow rate and kinetic luminosity are typical of AGN whereintense feedback is at work. HE 02381904 was detected in the XMM Slew Survey,but no Xray spectrum of this exceptional object has ever been acquired with anymajor Xray observatory. Our aim is to obtain for the first time highqualityXray data of HE 02381904, in order to understand the physical properties ofits innermost regions, in terms of obscuration, intrinsic spectral shape, andpossible presence of an Xray counterpart to the UV wind. This observation willshed new light on the link between efficient accretion, powerful winds, and AGN feedback. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
