| Description | We propose an XMM exposure of the SXWQ PG1700+518. SXWQs usually show a soft X-ray flux fainter by more than an order of magnitude with respect to normal optically selected QSOs, because of X-ray absorbing winds/nuclear outflows, or peculiar physical states. The SXWQ classification may exhibit a transient behaviour; therefore, monitoring these peculiar objects can provide a unique opportunity to shed light on the accretion flow and nuclear outflows mechanisms in AGN. We aim at investigating the nature of PG1700+518 with sensible pointed observations,checking for any spectral and/or flux variability. With the proposed observation, all the SXWQs in the well-studied PG Bright Quasar survey will be observed at least once by XMM, gathering high quality homogeneous X-ray data for all these sources. |

| 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. |
