Jacco Vink works in the field of high-energy astrophysics, mostly studying supernova remnants, but he has also published on neutron stars, AGN, and clusters of galaxies. Although interested in all aspects of supernova remnants, from the freshly synthesized atoms they contain to their dynamics, he currently focuses on their cosmic-ray acceleration properties, both from theoretical and observational perspectives. His studies include almost the entire range of the spectrum: radio, optical, X-rays and gamma-rays. He is a member of the H.E.S.S. Collaboration, which operates the H.E.S.S. gamma-ray observatory. He has taught courses on cosmology, high-energy astrophysics, compact stars, and astroparticle physics.
