Povzetek predavanja (v angleščini):

About half of the ordinary matter is still missing from the census of the baryons in the local universe. Cosmological simulations show that they should be hidden in the large-scale filamentary distribution of the cosmic web as warm-hot (logT=5-7 K) tenuous (10-6 - 10-5 cm-3) intergalactic gas (WHIM) weakly emitting in the Far UV/X-rays and therefore very difficult to detect with current instruments. Focusing on the X-rays, where the majority of the missing baryons can be identified, I will show and discuss the most promising WHIM detections.
