Dynamical evolution of small galaxy systems

Lines connect the coordinator with its partners. CORDIS does not always give exact coordinates for projects before 2014. These points are placed at city or country level.

Project objective

Detailed available data on compact groups of galaxies still have to be fitted in a consistent cosmological context. Specifically, no comparison exists between the observed space density of compact groups and the predictions of cosmological models. I propose to use numerical simulations to estimate the formation rate and the current space density of compact groups based on my recent demonstration that these systems form in short-lived structures within rich looser groups. These properties are expected to be sensitive to the cosmological model chosen and so may discriminate between otherwise possible models. This proposal fits within a major project currently under way at the MPA which involves cosmological simulations on parallel computers including gas dynamics effects. I will use simulations run on a Cray T3E to be installed in Garching in early 1996. These simulations will allow me to understand the evolution of compact groups in a cosmological context and their relation to the origin and transformation of galaxy morphology.
