PhD Theses

The department is engaged in the training of prospective astronomers at the undergraduate, postgraduate, and doctoral levels. This is done in collaboration with neighbouring universities, namely Bonn and Cologne. International partnerships have also been formed with institutions such as Würzburg and Valencia.

Bachelor & Master

Research projects at the undergraduate level (bachelor and master) in the above mentioned topics are possible at the group. Please contact Prof. Eduardo Ros about this possibility for potential topics.

PhD Projects

Doctoral studies are possible in the framework of the International Max Planck Research School (IMPRS). A list of available PhD projects and supervisors is shown below. For more details, please check projects with code AZ at our IMPRS webpage.
