Our research focus is broad and covers theoretical and observational questions in gravity and astrophysics
First, we explore the quantum nature of gravity and how it interacts with elementary particle. We focus on several distinct approaches to quantum gravity, most importantly asymptotically safe gravity, where we have discovered new ways to confront the theoretical approach with observations.
Second, we explore gravity in extreme astrophysical environments, namely around black holes and neutron stars. We simulate gravitational waves that are generated by mergers of these extreme objects. Moreover, we are part of the Event Horizon Telescope Collaboration that has taken humanity’s first ever image of a black hole.
Third, we bring theoretical models of gravity together with astrophysics research, and explore, how images of black holes can allow us to test the theory of general relativity and its alternatives.

At SDU, you can specialise in astronomy as a bachelor student. The courses include fundamental astronomy, astrophysics and fundamental cosmology and provide both theoretical lectures and observation nights. You can learn about fundamental aspects of gravity, including quantum gravity, both on bachelor and master’s level, for instance in the courses on general relativity and Introduction to quantum gravity. You can also participate in research on astrophysics and gravity as part of a project during your studies, or even write your BA and/or MA thesis in this area. You can also take an astronomy education for upper secondary school teachers (only in Danish).
