EA: Gas shocks around galaxy clusters – Rost
April 21, 2022 @ 12:00 pm - 12:15 pm
Gas shocks occur naturally around galaxy clusters, among several processes, the high-speed infalling gas deaccelerates and heats up near the centre of the cluster. The material infalling towards these objects is not completely isotropic, in general, we observe a filamentary structure that connects the surroundings. In this work we study how the shock and accretion occur around the cosmological filaments attached to these galaxy clusters, taking into account the dynamic state and the mass of the clusters. We observe that hot, impacted gas engulfs both the filaments and the cluster, while cold gas is injected into the cluster through the filaments.
