Two of the most fundamental questions in astrophysics are the conversion of molecular gas into stars and how this physical process is a function of environments on all scales, ranging from planetary systems, stellar clusters, galaxies to galaxy clusters. The main goal of this internal project is to get insight into the formation and evolution of galaxies from the cold interstellar medium. This is achieved by probing the cold molecular gas, the fuel of star formation, and dust, the by-product of this formation process, in galaxies across cosmic time. The studies are mainly based on observations in the far-infrared and radio wavelength regime with a special focus on radio interferometric observations with state-of-the art telescopes such as NOEMA, ALMA, ATCA, VLA and SMA. There will be close interrelation with other internal research projects e.g., providing our expertise on radio (interferometric) observations of galaxies. The research group will characterize the star-formation properties of massive galaxies in the distant universe at different epochs enabling us to study the formation sequence of star-forming galaxies. Furthermore, to probe the environmental-dependent evolution, the investigated sources are selected from galaxy clusters and the field. In addition, complementary studies of nearby galaxies (selected from CALIFA and WEAVE-APERTIF) serve as a local reference sample for future studies of high-redshift galaxies.
