ISM / Radio Material Interaction Modeling

With the outcoming of high angular resolution imaging and 3D spectrographic facilities (HST, TIGER-OASIS at the CFH Telescope…), the need of spatially resolved theoretical models of the kinematic interaction of radio material with the ISM (or the IGM for radio-galaxies) is increasing dramatically. In order to fill the gap between pure hydro dynamical models (3D approach, but very poor atomic physic) and photoionisation/shocks ones (planar description, full account for atomic physic processes), we have started to develop 2D or 3D hydro dynamical models including a good description of atomic physic processes (using photoionisation routines from the code MAPPINGS).

ATOMIC COLLISIONS WITH HEAVY IONS—RECENT DEVELOPMENTS AT GSI

The interaction of very heavy ions with matter at high velocities is considered emphasizing bio-physical aspects. A status report on the new accelerator facility SIS-ESR including the raster scan system is given. First atomic physic experiments are reviewed. X-ray emission experiments, ion-electron recombination, and an experiment to the bound beta-decay are treated in more detail.
