EVIDENCE FOR WHIM IN THE ANGULAR CORRELATION OF THE DIFFUSE X-RAY BACKGROUND

We propose a study of the angular correlation in the diffuse Xray backgroundpointing toward a low hydrogen column density, high latitude line of sight nearthe Eridanus xray enhancement. The observation will allow an accuratedetermination of the angular autocorrelation function on the scale 0..530.which is almost unexplored so far, and which is expected to contain informationon the Xray emission due to the WarmHot Intergalactic Medium. The contributionof the foreground will be removed using a pointing toward MBM20, a nearby highdensity cloud. The shadow of the cloud will also be used to study the energydistribution of the Xray foreground in the energy range 0.22 keV, to separateOVII, OVIII and FeXVII lines and study the composition and evolution of the local bubble. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
