Missing baryons and the large-scale structure of the Universe
A significant fraction of the predicted baryons remains undetected in the local Universe. These missing baryons are expected to reside within cosmic filaments in the Warm-Hot Intergalactic Medium (WHIM). With the use of the EAGLE simulation and the Bisous filament finding method, I will present the spatial and thermal distribution of the hottest WHIM in the Cosmic Web. At temperatures above log T(K) > 5.5, this hot WHIM can be traced by OVII absorption in the X-ray range, but detections have so far remained elusive. Taking advantage of the simulation, I will describe the distribution and spread of both Oxygen and OVII beyond virialised structures into the Bisous filaments. Finally, I will introduce observation predictions for future X-ray instruments to aid in solving the cosmological missing baryons problem.
