Abstract X-ray absorption lines in QSO spectra provide us a method to findcosmologically distributed hot gas. Recently both numerical simulations andobservations show a large fraction of baryons could be in a highly ionizedstate. These baryons could either co-locate with quasar heavy metalabsorption systems or hot, diffused intracluster medium. Here wepropose three targets PG 1407+256, PKS 2135-14, HS 0624+6907. Thesuperior energy resolving power of XMM RGS provide a very good chance to detectabsorption lines between 0.3 and 2 keV. We propose RGS observations of threebright QSO at moderate redshift in order to detect X-ray absorption lines fromthe hot component of the intergalactic medium.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
