Self Gravitating Systems, Galactic Structures and Galactic Dynamics

The investigation of the gravitational equilibrium of self-gravitating masses as initiated by Newton, during several centuries has been impressively extended both from the classical and the relativistic point of view.

Within this conceptual framework, the topics studied by the research group scientists are:
• General theory of relativistic and non relativistic self gravitating fluids
• Self gravitating systems: analytic solutions
• Self gravitating systems: numerical Solutions
• Self gravitating systems: acoustic induced geometries
• Relativistic MHD
