Description
I will discuss the role of non-thermal pressure support as a major source of the difference between the hydrostatic and the total ``true'' halo mass in galaxy clusters. I will present new models and methods to constrain the non-thermal pressure, highlighting the role of the next generation of X-ray observatories, like XRISM and Athena, in constructing a consistent picture of the formation and composition in mass and energy of galaxy clusters.
