Description
With the use of the EAGLE simulation, I will present the spatial and thermal distribution of the baryons within the filaments of the Cosmic Web. In particular, I will characterise the properties of the hottest (log T(K) > 5.5) Warm-Hot Intergalactic Medium (WHIM), which remains largely undetected and is a candidate to solve the cosmological missing baryons problem. Due to its high temperature, the hot WHIM can be traced by OVII absorption in the X-ray range. For this end, I will introduce observation predictions for future X-ray instruments.
