Description The discovery in X-rays of almost ubiquitous ultra-fast outflows in Seyfert and radio galaxies suggests that nuclear winds are common and that they may activate feedback processes between AGN and the bulges of their host galaxies. X-ray absorption features have been observed also in four distant QSO, three of which gravitationally lensed. We propose to point for 75 ks each a couple of bright, lensed and distant QSO: B1422+231 and MG0414+0534. Our goal is to characterize their X-ray spectrum and to detect blueshifted absorption lines so as to probe the existence of fast outflows at high redshift. We also expect that deep pointings will allow to put strong constraints on the parameters describing geometry of the accretion flow at cosmological distances.

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.
