| Description | We propose a 1.6 Ms XMM-Newton ..Very Large Program. to settle unambiguously one of the most controversial and open problems of modern astrophysics: the existence of the missing baryons in a WHIM. We will do so by complementing the first successful exploratory LETG observation of the z>0.4 blazar 1ESvirgul1553+113, with additional 1.6 Ms of XMM-Newton RGS time, so more than doubling the S/N and thus the absorption line equivalent width sensitivity of the currently available LETG spectrum in the fundamental spectral region of the intervening oxygen. The proposed observation will enable:(1) the solution to the missing-baryon problem; (2) a robust estimate of the WHIM metallicity; (3) pioneering studiesof thermo- and chemo-dynamics of the IGM with cosmic time and so of the diffuse-gas/galaxies interplay. |

| 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. |
