New Ion Detection in Space
Our experimental measurements confirm the presence of a new hydrocarbon ion, H2C3H+, in the cold molecular cloud TMC-1.
Laboratory Astrophysics & Spectroscopy
In the Laboratory Astrophysics Group we investigate the quantum physics of interstellar molecules. We develop special spectroscopic techniques to hunt for new molecules in the laboratory and in space.
