| Description | 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. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
