| 摘 要： | The Partner Group does research in cosmology, focussing on the quantitative modeling of the structure and evolution of galaxies and galaxy clusters, the pattern of galaxies and of larger structures. The usual approach in this field is the dark matter paradigm, i.e. the assumption that the basic structures are laid out in a matter component of particles which interact only gravitationally. Numerical simulations of large scale and high resolution are used to follow the evolution of condensations of dark matter particles during cosmological evolution. Analytic models and detailed statistical investigations of astronomical data sets supplement the numerical work.
