The X-IFU that will be on board of Athena will allow a major breakthrough in our understanding of the physics of galaxy clusters. Besides thermodynamics quantities, such as density and temperature, that are already measurable by current X-ray instruments, the X-IFU will unveil the kinematics of the intracluster medium, mapping gas velocity and velocity dispersion by studying the emission lines of heavy elements.
