Studying the Intergalactic Medium Through X-ray Absorption Lines
收藏资源简介：
Xray 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 colocate with quasar heavy metalabsorption systems or hot, diffused intracluster medium. Here wepropose three targets PG 1407+256, PKS 213514, 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 Xray absorption lines fromthe hot component of the intergalactic medium. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
