|Title||Counting the Baryons in the Local Universe with XMM-Newton|

|Description||We propose to observe the bright (F(0.5-2 keV) = 1.1 mCrab) and relatively high redshift (z=0.361) blazar 1ES 1028+511 with XMM-Newton for 500 ks, to quadruple the number of known OVII Warm Hot Intergalactic Medium (WHIM) filaments and reduce threefold the statistical error on Omega_b(WHIM). This long XMM-Newton observation will probe a 14.2 times longer path-length than our Mkn 421 discovery spectrum ( H_0 = 70 km-s-Mpc), and in a sight line already probed by our pilot Chandra observation. The long pathlength and the large area of the XMM-Newton RGS assures the > 3 sigma detection of 5-6 new OVII WHIM systems down to N_OVII >= 2.2e15 cm-2, in the proposed 500 ks.|

|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.
