Molecular astrophysics is now in a golden age, as new-generation telescopes such as ALMA and NOEMA remind us every day the importance of laboratory data on molecular transitions and reaction rates. High sensitivity observations in the direction of Galactic and extragalactic sources have revealed a chemically rich universe, where simple radicals as well as complex organic molecules thrive. This is extremely important for astrophyics, as molecular spectra are unique tools to study the dynamical evolution of interstellar clouds, where stars and planets are forming. For this, accurate transitions frequencies measured in the laboratories are required. Molecular line observations also give us the opportunity to study the chemical composition during the various steps toward star and planet formation. Thus, interstellar molecules allow us to gain understanding on the evolution of chemical complexity from the cold and quiescent pre-stellar clouds where stars form, to the hot protostellar envelopes, to protoplanetary disks where planets are assembled, to exoplanet atmospheres, to comets and carbonaceous chondrites in our Solar System. To achieve this, observations have to be coupled to chemical models, which need reaction rates measured in the laboratory. In general, laboratory work is sorely needed to fully exploit the multitude of astrophysical data which have been and are being collected at an ever increasing rate. In this workshop, the German laboratory astrophysical community will meet together with international experts on molecular spectroscopy, interstellar dust, ice experiments and theoretical chemistry. The interplay of gas-phase and solid material in space and in the laboratories, as well as the dust evolution in interstellar clouds will also be discussed, focussing on the comparison between astronomical observations, experimental results and theoretical predictions.



The workshop is supported by the DFG priority program 1573  "Physics of the Interstellar Medium".
