摘要: Detecting the thermal and non-thermal emission from shocked cosmic gas surrounding large-scale structures represents a challenge for observations, as well unique window into physics of warm-hot intergalactic medium. In this work, we present synthetic radio X-ray surveys large cosmological simulations in order to assess chances jointly detecting web both frequency ranges. We then propose best observing strategies tailored existing (LOFAR, MWA XMM) or future instruments (SKA-LOW SKA-MID, ATHENA eROSITA). find that most promising targets are extreme peripheries galaxy clusters an early merging stage, where merger causes fast compression onto virial region. By taking advantage detection band, deep observations will probe emission, help us study plasma conditions dynamic medium with unprecedented detail.
