The space between the stars is not empty, but filled with interstellar matter. Interstellar matter displays many very different physical properties. On one hand, stars have their birthplaces in the densest parts of interstellar clouds, where we find molecules intermixed with dust. On the other hand, we observe interstellar medium full of fissures, caused by the explosion of a dying star at the of its life. The star returns mass and energy back to the interstellar medium. As a result, we see shock waves penetrating the interstellar medium and heating up the gas to millions of degrees Kelvin.
The
Radioastronomische Institut der Universität Bonn
studies in particular the cold and the hot phase
of the interstellar Medium of the Milky Way.
In the framework of a "Sonderforschungsbereich" (SFB),
in collaboration with the
1. Physikalischen Institut der Universität zu Köln
and the
Max-Planck-Institut für Radioastronomie
we study the interaction between star formation and the dynamics
of galactic halos and galaxies with low mass content.

ISM Homepage,
and the corresponding internet pages of the
KOSMA,
X-ray and HI group .
At the Sternwarte
investigations concentrate on the very local gas, gas in the Milky Way halo,
and gas in the Magellanic Clouds,
using visual and ultraviolet (IUE, ORFEUS, FUSE) data.
Further information on the research topics of the Sternwarte can be
found on the
interstellar matter and
Magellanic Clouds homepage.
