SFB 956 - Conditions and Impact of Star Formation

Funding for our work on galaxy formation, the IGM and reionization is provided by a grant from the SFB. The SFB 956 combines the unique expertise of the participating astrophysics groups in Cologne and Bonn towards three main goals: On the science side, the unique upcoming opportunities with the opening of the complete submm/far-infrared range of the electromagnetic spectrum and the interferometric access to highest angular resolution from radio to infrared wavelengths will be used to investigate and understand the basic processes and their dependence on the physical and chemical environment in interstellar space, by which interstellar clouds aggregate and finally collapse to form new stars. These conditions for star formation are on one hand significantly influenced by the energetic feedback from recently formed stars and by the chemical composition of the interstellar medium as a result of the elements synthesized in previous stellar generations. On the other hand, the conditions are a result of external dynamical impact such as the merging of galaxies, leading to star bursts, or the interaction of interstellar matter with jets and central winds in Active Galactic Nuclei.

The SFB 956 brings together expertise from the Argelander-Institut für Astronomie, Universität Bonn, the Max-Planck-Institut für Radioastronomie, Bonn, and the Physikalisches Institut, Universität zu Köln.
