Radio astronomical measurements allow the study of a variety of questions in fundamental physics. Those questions range from the equation-of-state of super-dense matter to the investigation of fundamental forces such as gravity and magnetism.

The research team uses the millimetre- and sub-millimetre range of the electromagnetic spectrum to observe various phenomena in the universe. The cosmic background radiation is also being investigated, as well as molecular clouds in the Milky Way and other galaxies.

By employing radio-interferometry, extragalactic objects and their centres are investigated in great detail. The Very Long Base Line Interferometry (VLBI) method is applied by correlating data from telescopes distributed worldwide and using them as a “giant“ combined telescope within the framework of coordinated arrays as the the European VLBI network (EVN). In addition, global VLBI experiments are conducted in cooperation with telescopes in the USA.
