Clusters of Galaxies: Structure and Dynamics in the Last 8 Gyr
  Clusters of galaxies, being dark matter dominated, have long been and still
are the ideal cosmological targets to study the nature of dark matter.
Constraints on the nature of dark matter comes in particular from the
observational determination of the distribution of total and baryonic mass in
clusters, by comparison with results from cosmological numerical simulations. I
present here past and recent results on this research topic.
