Robert Schmidt:

"X-ray observations and mass analysis of galaxy clusters"

Zusammenfassung. In this talk I use X-ray observations of galaxy clusters to study the properties of their dark matter halos. In particular, I will show how the most X-ray luminous, dynamically relaxed clusters can be used to test predictions from cold dark matter simulations regarding the mass profile and the mass-concentration relation. I conclude with some examples of the application of cluster mass determinations to the kinematics of galaxy clusters, the baryon fraction, and cosmology.
