How structures in the interstellar medium are generated

GENeration and Evolution of  Structures in the ISm
GENeration et Evolution des Structures du milieu InterStellaire

is a German/French collaboration project started 1.5. 2017 by the Deutsche Forschungsgemeinde (DFG) and the French Agence national de recherche (ANR).

The objective of this research project is to better understand the structure and evolution of molecular clouds in the interstellar medium (ISM) and to link cloud structure with star-formation.  For that, far-infrared observations of dust (Herschel) and cooling lines (SOFIA) are combined with ground-based submillimetre observations of molecular lines. Dedicated analysis tools will be used and developed to analyse the maps and compared to simulations in order to disentangle the underlying physical processes such as gravity, turbulence, magnetic fields, and radiation.

A new and innovative approach is to combine the competence of the members of the Cologne KOSMA group in structure identification methods and SOFIA with the expertise of the Bordeaux LAB star formation group in Herschel and spectro-imaging maps, and the Bordeaux GeoStat team of the INRIA institute who are experts in nonlinear methods for the analysis of complex systems.
