Welcome to the Homepage of the

Clusters of Galaxies & Cosmology Group at MPE

The research group, led by Hans Böhringer, is conducting observational and theoretical studies on the astronomy and astrophysics of galaxy clusters, and on the assessment of the large-scale structure of the Universe. These studies are undertaken mainly on the basis of the observed galaxy cluster population, and also form the basis for testing cosmological models. The research group is part of the theory division of MPE but also includes members of the X-ray astronomy and optical/interpretative astronomy divisions.

The main research topics of the group are

  • The structure of galaxy clusters
  • The physics and chemical composition of the X-ray luminous intra-cluster medium
  • The galaxy population of galaxy clusters
  • Galaxy cluster surveys
  • Study of the cosmic large-scale structure
  • Tests of cosmological models
The main activities are detailed X-ray studies of galaxy clusters with the satellite observatories XMM-Newton and Chandra, and optical studies, based mainly at the Chilean observatories of ESO and the German-Spanish observatory at Calar Alto. Through detailed data analysis, modeling, and simulations of the physics of galaxy clusters, we can gain insights into their evolution and their role in the large scale structure of the Universe. Our major goal is to contribute to the understanding of the formation of the visible large-scale structure of the Universe, and to develop more and more stringent tests of cosmological models. The upcoming eROSITA project will proviude us with data for a major breakthrough in this cluster cosmology research.
