I am an astronomer working with exploding stars and black holes. These are some of the most extreme phenomena in the universe. I am particularly interested in how the explosions are triggered and how ultrafast jets form in the vicinity of black holes. In practice, this means that I spend my days analysing data from different telescopes. To be able to study different kinds of phenomena I use observations that span most of the electromagnetic spectrum. For example, I use telescopes that can observe energetic X- and gamma-ray radiation in order to study jets, while optical observations with the Hubble Space Telescope are an excellent way of studying Supernova 1987A, the most nearby stellar explosion in our lifetimes.
