SP2: The astrophysics of galaxy groups and clusters
S. Ettori, G.W. Pratt, et al.
The impact of Athena on the study of galaxy group and cluster astrophysics, focussing on observations of nearby (z < 0.5) systems, where Athena will revolutionize our understanding of the basic process of energy transfer into the ICM, transform our view of the outer regions of galaxy clusters where material continues to accrete, and allow us to track the generation and diffusion of metals in the intracluster gas.
